TrafficViewer Pro Version History

All TrafficViewer Pro released versions and the changes in those versions are listed below.

Changes in TrafficViewer Pro
NewAdded a new Weekly Volume Report.
NewSignificantly improved multi-directional classification processing in most cases.
NewNew firmware is available for 4-channel counters. Firmware version 2.33. It is a recommended update. If the firmware gets installed on your computer you should be prompted up update your counters when they are plugged in. If not, you can download our firmware installer from our website.
NewNew firmware is available for 2-channel counters. Firmware version 2.30. It is a recommended update, especially if your counters are below 2.25. If the firmware gets installed on your computer you should be prompted up update your counters when they are plugged in. If not, you can download our firmware installer from our website.
NewAdded directional volume processing of count-only data. So with two tubes stretched across a multi-lane road (or parking lot entrance, etc.) if the tubes are close together (recommended under 1 foot) volume only counts can be determined based on the order in which the tubes are hit. A new checkbox "Directional Volume" is now on the "Data Settings"/hose layout screen, it is only enabled when "Unknown Hose Spacing" is checked and two hoses are across one or more lanes.
NewAdded command-line parameters to allow downloading data from a counter, choosing a hose setup, and saving and exporting the data, etc. all without using the user-interface. So data can be retrieved froma counter from within a batch file for automated processing. Using command-line arguments requires units with firmware version 2.25 or higher to work.
NewAdded some options to run an external program after exporting data. The options for this are in "Preferences" on the "Reports & Exports" tab.
NewAdded an option to set the default road layout for 2-channel and 4-channel counters in Preferences. So if you frequently use the same tube layout you can now go into Preferences, and on the "Proccessing Defaults" tab under "Layout Defaults" there are two buttons "2-Channel Layout" and "4-Channel Layout" where you can choose your default layouts.
NewAdded options for calculating the ADT and some help text on the report range selection screen for Weekly Volume reports. The default when not specifying an exact date/time range is not to show an ADT, and when specifying a start/stop range the default is to calculate it based on "Total Volume / # of Hours x 24".
NewAdded multi-lane classification with 4-channel counter as a short-short/long-long hose setup.
NewAdded "Graphical Timestamp View" back into the software. This can be helpful for troubleshooting classes and processing. It is accessed by selecting "View|Advanced|Graphical Timestamp View" from the menu at the top of the window while having a file open. The list of all timestamps is also available under "View|Advanced|Show Timestamp List".
NewThe day of week is now shown on reports along with the date.
NewAdded a report option to show the "comments" field on reports.
NewAdded a report option to hide file path information on reports.
NewAdded a new export type, "Geocounts" export. Currently only the axle count export is enabled, future support for vehicle or class exports may be added.
NewThere have been some moderate improvements in overall classification processing, probably more noticable in heavier traffic and at slower speeds.
NewAdded help text to several of the options at the bottom of the "Data Settings" screen, help is shown when the mouse is over the field.
NewAdded CountBuddy II firmware upgrade support.
FixThe built-in updater should now show as the publisher instead of showing as unknown publisher when prompting for access to perform the update.
FixFixed a bug that could cause data to be skewed in reports or exports in very specific circumstances -- it was more apt to occur, and be noticeable, in very light traffic. (If the selected report/export start time was on the same minute as a hose hit, the following data would be off by the number of minutes that there were no hose hits at all).
FixFixed a bug when the unit time's out or is otherwise disconnected after a download while sitting at the data settings (hose layout) screen. If the unit is disconnected before using the "Layout Selection" screen, then there were no layouts to choose from, it was blank. Now a unit can be disconnected and there will still be the normal layout options when clicking on "Select Layout".
FixFixed a display problem when a system was set to use a higher DPI for it's monitor (higher than 96DPI). Some controls would have their text cut-off and most notably the speed and classification grids ont he data overview screen would show only partial lines (i.e. the top half of the text) for each row in the grid. DPI scaling is no longer attempted so no text will be cut off due to a higher DPI setting.
FixFixed a bug with the hose setup description displayed on the data overview screen. Single hose setups would show a hose spacing, they no longer do.
FixFixed a bug that would occasionally allow a cluster to have 1 axle. While this typically wouldn't affect much, it could cause problems with "Always classify as..." and "Divide unclassified axles by" settings if used in a scheme's "Unclassified Handling" rules.
FixMoved buttons on "Data Overview" panel to the righthand side instead of at the bottom. This way, devices with low resolution screens can still click on the buttons. (On top of that there always has been the option to use the "File" menu in the upper-left of the screen for all of these tasks.)
FixFixed a problem when trying to "Export Scheme to CSV" in the scheme editor for a scheme that was created or modified. Now schemes can be exported (the only purpose of this is just to look at a table of spacings). Please note that some scheme types that don't test number of axles and axle spacings will not export (schemes that only use total spacing for example).
FixOther minor appearance-related changes.
Changes in TrafficViewer Pro
NewAdded a new "Allow limited-release firmware updates for units" checkbox in Preferences, on the "General" tab. When this is checked if we have a new firmware update available which is not yet a full public release then your units will be upgraded to that limited release. (We usually slowly issue firmware updates to groups of units for quite some time before making it a public release in case there is a problem with a new firmware version -- but if you are having problems you may want to try the latest firmware).
FixSome users are having problems with version 2.20 unit firmware (it appears most with the problems were downgrades from 2.23 or 2.24). We have issued a limited firmware release of version 2.25 which fixes several bugs. If you are having unit problems you may want to try the new 2.25 release before it is issued to everybody.
Changes in TrafficViewer Pro
FixIt has been determined that our new 2.23 and 2.24 firmware, which is only in a small group of units, has a bug and needs to be downgraded to 2.20. This update will allow downgrading units with 2.23 and 2.24 firmware.
Changes in TrafficViewer Pro
FixIncluded new firmware version 2.24. This unit firmware update will only occur if you have units with 2.23 firmware as that firmware has a bug. This is currently a limited release; versions before 2.23 will not yet be updated.
FixMinor cosmetic changes (typo, suite #, and copyright year changes).
Changes in TrafficViewer Pro
NewChanged the default Data Settings screen to use the new hose layout screen if no software was previously installed. The new layout screen also supports 4-channel counters. On upgrades from 1.3.x.x this is not the default but can be enabled by unchecking "Use old-style hose setup screen for 2-channel counters" on the "Processing Defaults" tab in "Preferences".
NewThe software now fully supports our new PicoCount 4500 4-channel counter with all setups except 4-channel (short/long) classification which will be added later.
NewMade major internal enhancements to how dates and times are stored and processed, this should have a slight speed improvement along with other benefits.
NewAdded a "Calculate Dwell" button to help come up with good dwells based on the "Posted Speed" entered. By default the dwell is calculated to not filter out hits within 48 inches (122cm) of each other at the posted speed. Which should allow heavy trucks multi-axles. This value can be adjusted in the Preferences screens under the "Processing Defaults" tab.
NewModified counts only setups to use a new redundant display method if hoses are across the same lanes. Instead of just using hose A for the lane, now if hoses are across the all the same lanes (in counts only setups), the software will use the hose with the most hits each minute (so if a hose breaks or has a crack it will switch to using the other hose for that period). This should result in the best possible data.
NewLanes with the same name (or direction) will now automatically get the channel(s) added to the name so they can be identified easily. But, as always, you can give the lanes any name you want so the ability to identify them yourself is still there. NOTE: This only occurs when using the new hose setup screen, the old setup screen will behave the same if you choose to use that.
NewThe print and export range selection screen and multiple-file export screen was changed slightly to more easily accomodate additional report types and more then 2 lanes.
NewAdded the ability to change the hardware dwell in PicoCount 2500 units made after March, 2012. Changing the hardware dwell inside the unit is NOT recommended (you will more than likely get worse results with your collected data). It should normally be left at 30ms unless you have good reason to change it (i.e. it's required by a contract). This new hardware dwell can be changed by clicking on the "Configure Unit" button (where the Unit ID is located).
NewWhen exporting multiple files at once the multiple file save dialog now has several options for a "base filename" that can be used, instead of just the default date/time.
NewAdded the ability to change the percentages, text, and colors on the quality meters that are displayed for classification data. This will allow users to set more appropriate percentages that they find acceptable. Meters can even be turned off individually.
NewAdded a few additional tests to the unit connection screen. If the memory usages, or the unit's date/time or start date/time are invalid the field will be highlighted and help text will show if the mouse is over these fields. While this will help catch a rare instance where the unit has a problem, it is mainly to get the user's attention after a unit's firmware has been updated -- in that case it is common for these values to be out of normal ranges and this is easily corrected by clicking on "Clear Unit Data" after the firmware update.
NewAdded the ability to save data files in the format used in version 1.3.x.x of the software since the data file format has changed slightly since then and version 1.3.x.x has been in use for quite some time. This feature is available under the "File" menu at the top of TrafficViewer Pro by clicking on "File", then "Advanced" and finally "Save data in v1.3.x.x format".
FixAdded All-In-One CSV exports back into the beta software. They were removed when the exports were cleaned up/rewritten with the first release of 1.4.x.x (beta). The "Export Version" field in the header of the CSV will now be "All V2.03". The main change to the CSV layout is that the data columns will no longer be in a strange order as they may have been in 1.3.x.x.
FixFixed a 1-minute skew when specifying specific times for a range of data to print or export. (This did not affect data when using the "# of days" range selection.)
FixFixed the axle spacings in the "Vehicle List" (vehicle timestamps) Export. The spacings were always exported in Metric (centimeters) even if measurements were selected to be in English units. Now it will export centimeters or inches appropriately. The Export Version field in the CSV header for vehicle timestamp exports was increased, it now reads: "VehicleTS V2.12".
FixFixed the CSV exports so that multiple directions can be exported to multiple files at once.
FixOn the speed reports the Median and Modal speeds were incorrect, this has been fixed. Previously the modal speed shown on the reports was actually the calculation for median speed, and the median speed shown on the reports was a wrong calculation and could have been far off of the other types of averages.
FixMade a very slight change in how short/long hose setups are calculated. If throughout the course of a minute there were only vehicles in the short hose lane, then there is a chance that the long hose could have one less hit than the short hose (if the short hose is leading the long) if the minute changes after a tire cross the short but before it crosses the long hose. This had a very minor affect of causing an overcount of one hit (if there was another set of odd axles to pair with it would be 1 vehicle count off in a divide by 2 scenario). Partial undercounts are now carried over so they are properly accounted for.
FixChanged the wording in the window that pops up to confirm clearing unit data. All references to "reset unit" were removed for clarification.
FixRemoved all file types that we don't actually open from the Open and Save File listings. These will be added back in if we add support for these file types.
FixFixed a bug when trying to print a report when there was less than one minute of data in the unit, it would cause an "access violation".
FixA message is now displayed in the data setup screen if a two lane classificaiton setup is selected and the lanes are both set in the same direction. Those setups will be saved as a single lane -- there is no way to tell the lanes apart when both hoses are across both lanes of the data in the same travel direction.
FixClassification Scheme/Rules Editor now defaults to inches or centimeters based on the measurement set in your preferences (English/Metric) when opened for the first time, instead defaulting to centimeters.
FixNOTE: All CSV exports have changed slightly (to allow for the new possible lanes with 4-channel counters and because there's only one dwell time in the header now). So all CSV versions in their headers have had their version increased. Be sure to test this if you automate the importing into other software.
FixChanged the text on the "Reset Unit" button to read "Clear Unit Data" to make it easier for first time users to understand it's intended use.
FixGreatly improved the processing speed and memory usage for portions of time with no data. This will improve processing times greatly for any counters that sat on the shelf for long periods of time and were not reset before using. It will improve the memory use and processing speed of all studies to some extent (light traffic will have the most improvement on processing speed). This should also fix the "EEFACE" error which was displayed when processing some data when memory ran out.
FixWhen specifying a specific date/time range the start time will be rounded up if it's not on a whole interval, and the stop time will be rounded down instead of always rounding to the nearest interval.
FixRemoved pop-up error message if communications log file cannot be written to. So now those systems with permissions that don't allow the log file to be created will no longer pop up an error message every time the software is opened.
FixThe graphical timestamp display is currently being revised and is temporarily disabled.
FixFixed a bug with a missing quote in the header of timestamp exports.
FixFixed a bug with timestamp exports that were exported as "Seconds since start date/time". The timestamps were not out of skew with each other but they may have been several seconds off from the start time shown in the file (timestampts were being calculated from the start time shown but were also using the seconds from when the unit was reset which were not displayed in the file). Now all timestamp exports in this format are in seconds from the time shown with :00 seconds (if the start time in the file is 16:26, the timestamps in seconds are from 16:26:00 as one would expect). Timestamp exports in the more common formats of "Readable date/time" or "Days since Dec 30, 1899" were already exported properly.
FixFixed a bug that could occur when there was a failure to download data from a unit (which is a very rare condition -- such as unplugging a unit during download). It could have caused TrafficViewer Pro to crash or otherwise behave strangely.
FixFixed a bug with multi-lane processing when the software attempted to recluster (which happens in heavy traffic). This could have caused an "Access Violation" or other strange behavior while processing.
FixFixed installer to install under all users instead of the currently logged in user. Which caused problems when logged in as Administrator. This should work just fine for Windows XP through Windows 8.
FixCleaned up the text descriptions for median and "unknown spacing" setups.
FixRemoved the "Total" from the overview screen display if there is only one lane in the setup.
FixExporting of mulitple files no matter the type of export should now be handled better.
FixSeveral other minor enhancements and fixes.
Changes in TrafficViewer Pro
FixThe software will now recognize special CountBuddy timestamps that units with the new 2.20 firmware store when a CountBuddy is plugged in. So now if you use a CountBuddy on a unit with the 2.20 firmware you won't see the "corrupt bytes" message when downloading. (The data is/was not affected, the message was just shown incorrectly.)
FixChanged the names of two buttons so they match the new names used in the beta software. The "Reset Unit" button is now labeled "Clear Unit Data", and the "Edit Header" button is now the "Data Settings" button. The buttons do the same thing, renaming them is just an attempt to make the software slightly more user-friendly for new users. The title of the "Data Setup" screen was also changed to "Data Settings" to match the button.
Changes in TrafficViewer Pro
NewNew PicoCount 2500 firmware is available, the new firmware version is V2.20. It is recommended that you upgrade your units. This new firmware fixes a rare (but major) bug and now performs error correcting on the flash data storage.
NewAdded new security features for the PicoCount 2500 (unit passwords) for units with firmware version 2.15 or higher. For these units the "Configure Unit" screen will have the ability to enable unit passwords on each unit.
NewAdded WSDOT exports (GK Export).
NewSoftware now supports time-limited PicoCount rentals/demo units.
FixFixed a bug in the communications routines that may have caused some strange behavior at times.
FixFixed a potential bug with PDF exporting not working on some Windows 7 installs where the USP10.DLL file may have been an incompatible version.
FixRemoved file type associations from the Preferences panel, as it stands that was not functional in Windows Vista or 7. File type association will be introduced in the installer and perhaps added back to the Preferences panel at a later time.
NewAdded a completely customizable automated filename for PRN exports. At the bottom of the PRN filename formats there is now the option "- CUSTOM FILENAME FORMAT -", which will give you a button "Edit Custom Format" to create your own filename format. This can also be setup in preferences to use as a default.
NewAdded new V1.11 RetroCount firmware to upgrade RK-1 units to work better with some serial cables/ports that they were having some trouble with before.
NewAdded Road Tube Simulator 8 to known devices to allow for firmware updates.
NewAdded a "Configure Unit" screen for the Road Tube Simulator to allow a very basic way to modify the patterns and vehicle tables that the simulator uses for it's output.
NewAdded FDOT PRN export.
NewAdded INDOT PRN export.
NewMultiple export selections (multiple directions and/or data types) can now be exported at one time with PRN exports (they were previously limited to exporting one direction or type of data at a time).
FixFixed a bug in processing data, specifically during the building of "clusters" of axles, some of the newer speed testing code was inadvertantly not being used. This fix may help improve some data that has excess noise on the hoses, or may improve processing speeds slightly.
FixFixed the help text on the "Speed Bins" tab in "Preferences" which was previously cut off and added some additional notes to the help text.
Changes in TrafficViewer Pro
NewAdded "All-In-One" export for PRN formats. You can now choose "All-In-One" from the selection list for any of the PRN exports and all class and speed data will be exported into the same PRN file.
NewImproved processing of data in some cases with extra noise on the hose. The software is now less likely to insert a false missing hit in some areas of data where there is noise on the hose or where hose echo is further out than the dwells.
NewAdded some ability to support the PicoCount 4500 (unit should connect, firmware updates should work, and A/B channels should function as a 2500). Next update should add full support.
Changes in TrafficViewer Pro
NewAdded several new interval selections for both reports and exports; any interval that divides evenly into 60 minutes can now be used.
NewReport and export settings that can be set before exporting or printing will now stay at what they were last set at while the same file is open. This will make it easier to export the same range of data that was just printed, or to print/export multiple reports/exports without having to re-select the date/time range or change other settings again.
NewAdded "Interval" to header of CSV files. The "Export Version" for each of the exports has been increased to reflect the change in the header. The format of the new "Interval" field is "n Min" where n is the interval in minutes.
NewThe "Bin Interval" option located in Preferences will now be the default interval used for both reports and exports, previously it was only used for exports.
NewAdded a warning message when printing large reports (in case the wrong settings were selected, such as a small interval or a large date range).
FixFixed several bugs with speed statistics shown at the bottom of the speed reports. Speed statistics on multiple page reports were being calculated incorrectly on all but the first page of data. Also, several speed stats were being calculated incorrectly since version when the new speed bins were added.
FixFixed a bug with the All-In-One export, if the start date/time was set past the end of data the export could have caused an access violation message to pop up.
FixFixed a bug in the export selection. When only selecting "All-In-One" for exporting, the "Continue" button would stay disabled until another type of export was selected.
FixRemoved "Volume (axles)" selection from the report list which was accidentally added to it in version It was non-functional (it only generated a blank page) since it is for exporting only and was not intended to be displayed for reports.
Changes in TrafficViewer Pro
FixAdded Baud rate adjusting code to the download. A quick test at the start of the download will determine if the download should be attempted at 115.2k Baud if there is difficulty communicating at 921.6k Baud.
NewA new firmware update is available for PicoCount 2500 units (V2.12), this update specifically addresses a problem with some units being unable to download at 921.6k Baud.
Changes in TrafficViewer Pro
NewImproved processing in a few circumstances (most areas affected will be areas of data with missing hits, and in heavier traffic). The biggest change was to make sure axles are matched up properly, there is a speed check with nearby axle hits to make sure we have a speed that is even possible.
NewImproved algorithm that detects and inserts missing hose hits (only done with hoses set up for classifications). It should do a better job and not falsely inserting hits in areas of very noisy data.
NewThe auto-update feature was disabled by default in previous installations. It is highly recommended to have this enabled. Starting with this version new installations will ask if the user wants to turn auto-updating on. Also, updating to this version from an older version will also prompt the user and ask if they would like to enable it if it's disabled. Users will only be asked one time.
NewModified speed report to split column titles into two rows when a hyphen or space is encountered. This makes the column titles less cluttered and easier to read with larger speeds (commonly the case when displaying speeds in KPH).
NewAdded a recent files list to the "File" pulldown menu at the top of the main TrafficViewer Pro window. The 10 most recently opened or saved files will be listed there, most recent at the top of the list.
NewAdded new "MH Class" scheme (an FHWA variation).
NewAdded "Nevada DOT Lengths" scheme (a pure length-based scheme).
NewSample data files are now included with installater and are an optional part of the install.
FixChanged the dwell handling in the TrafficViewer Pro so that it works as it was intended to work. This is rather subtle, and likely won't have a dramatic positive or negative effect on data -- it just needed to work how it was being described. It was coded like this: "After a hit occurs, all hits on that channel will be filtered out until no hits occur for the entire length of the dwell time. If a hit does occurs within the dwell time the dwell time starts over, this repeats until the entire length of the dwell occurs with no hits." How it works now, which is how it was intended, is: "The amount of time after a hit occurs that other hits will be ignored on that channel."
FixFixed/improved "Data Quality" meter slightly. Some hits that were not clustered were not impacting the data quality, now all hits are accounted for. It's likely this meter will read slightly lower than before with most data. The description of this meter has also been updated in the "What is this?" help screen.
FixFixed a bug in the display of the speed grid on the overview screen. With bi-directional data, a "List index out of bounds (-1)" may have been displayed. (This bug was introduced in with the speed bin changes.)
FixFixed a processing bug that could cause an "External Exception" and processing to not complete. This was extremely unlikely to ever happen in any real data. This could occur only when a cluster had exactly 256 axles in it and it somehow passed the classification scheme tests for a successful vehicle classification.
FixFixed a couple of bugs in the connection log. Serial numbers are now stored to the log in an easily readable format and battery voltages are stored in the log for units that can read it.
FixFixed a "divide by zero" error when using the unclassified cluster handling "divide unclassified axles by..." option.
FixFixed a memory leak (a very small one) that could occur on installations that have multiple firmware versions available for the same product (due to other circumstances this was unlikely to even occur on any normal installations).
FixFixed a bug in the classification editor. Moving a rule from the top of the list down would cause an access violation and the scheme would no longer work.
FixFixed a problem in the "Report Selection" window. When selecting only "Class Totals" or "Speed Totals" and nothing else, the "Continue" button would remain disabled. The "Continue" button now works with all checkboxes.
FixFixed a few minor user interface issues in the "Data Setup" panel. Tabs will now cycle through controls on this panel in a normal order and the controls and text in the "Axle Correction Factors" view were moved around slightly so no text is up against the right side of the panel.
FixFixed some bugs in the PRN exporting due to the ranges chosen. Mainly, PRN exports would only export 1 day of data if "split days into separate files" was not checked. Now the range selection should work as intended, even when "split days into separate files" is not checked.
FixFixed the stop date that was exported in PRN exports when "split days into separate files" was not checked. Previously the stop date in the PRN file would always show the same date as the start date, it is now the proper stop date (the last date/time of data in that file) no matter what range of data is exported to the PRN file.
Changes in TrafficViewer Pro
NewAdded additional unit testing to detect potential upcoming problems before they are severe (by reading the unit's battery voltage). A message will be notify the user to contact us for a replacement unit.
FixFixed display of ampersands in location/comments fields of the data overview panel (they previously displayed as an underscore).
FixFixed a missing quote in the timestamp exports. It was a missing quote on the new ""Time Stamp Format:" header line added last release.
Changes in TrafficViewer Pro
NewAdded custom speed bins. You can change the speed bins that are used in "Preferences" under the "Speed Bins" tab.
NewThe timestamp exports now have 3 formats for the timestamp field. Previously it was only "seconds since start date/time", so remains the default. The new options are "days since Dec 30, 1899" (which spreadsheets know how to convert to a date/time just by indicating the field is a date/time), or "Readable date/time", which will export the date and time of each timestamp as text (in a readable format). NOTE: If your exports require millisecond or better resolutions, your most accurate timestamps will be exported using the original "seconds since start date/time" format.
NewAdded "Time Stamp Format:" as a field in the header of the timestamp CSV exports, the three values are the three types of formats: "Seconds", "Days", and "DateTime".
NewBoth vehicle and axle timestamp exports now have a new version due to the above changes, the new version for the "Export Version:" field is "V2.00". If you have software importing these, with any "V2.00" timestamp exports you should test the new "Time Stamp Format" field to determine the format of the timestamps.
NewAdded default settings for some of the export options that can be changed in "Preferences".
NewAdded "Number of Axle Spacings" to "Exports" tab of "Preferences". For those that use vehicle timestamp exports, this value is the number of spacings to export. Previously it was always 9 spacings that were exported, now it can be any number (or none at all). If you don't use the spacing data in your vehicle timestamp exports, you can set this to 0 so those fields will not show at all.
NewTo avoid confusion, the "Continue" button is now greyed out for report and export selection if no export/report type has been selected.
NewSpeed and volume reports should get generated more quickly now.
NewSpeed and All-In-One exports versions are now "V2.00" since the speed bins are now customizable there will not necessarily be 15 bins now, and the ranges may be different if they are changed from the defaults.
FixFixed a minor bug when closing TrafficViewer Pro that was attempting to access and free already freed memory.
FixFixed the page numbers of reports. Now all reports start at page 1 (volume, speed, and class), and the total pages indicator was removed (to speed up report generation).
FixFixed range selection for timestamp exports, previously the range selection was ignored for timestamp exports (even though the start date/time in the export showed the start time selected). Now timestamp exports will export only the range selected.
Changes in TrafficViewer Pro
NewAdded unit firmware checksumming, just in case a firmware update partially fails (or something else happens to the unit) then the unit firmware can easily be updated again.
FixNew PicoCount 2500 firmware (V2.11) to fix several potential issues that could have caused unit failure.
FixFixed a bug in processing that could sometimes "cluster" vehicles that were a long distance apart therefore at times causing missed vehicles in classification setups. The frequency of this occuring would have varied depending on the scheme used and data density; due to it's nature any data affected would likely have only a slight improvement. The quality meters would have still properly reflected any missed vehicles.
FixFixed a "Range Error" message that would pop up when TrafficViewer Pro was opened on some installations of beta versions between and
Changes in TrafficViewer Pro
NewChanged processing for hose setups that the software detects as possibly incorrect, the user was prompted more than once to change setups (each time printing or exporting) if they didn't change it the first time. Now, the prompt should only occur after changing the header or opening a file, and not before a report/export.
NewBehind the scenes, a lot of processing/reporting code was cleaned up and variables were made more consistent for easier future updates.
FixThe speed report/export had speed data shifted over one bin to the right (so it showed higher speeds). Now, reports/exports of speed data should be correct. Any old files can now be opened and new speed reports generated with the correct data. (Note: The all-in-one export did not have this problem)
FixFixed a bug with volume reports. When using a hose setup with a median, if the A/B hoses needed to be flipped, the report would show the wrong column titles (they were opposite what they should have been).
FixFixed a "floating point error" bug with the classification report/export when there were no trucks in the data.
FixFixed a problem when a scheme was created or modified to use different unclassified handling. It could cause an "Access Violation" to occur when processing, so reports or other data were not accessible. Custom schemes with all types of "unclassified handling" should now work.
FixFixed a couple of problems with "All-In-One" export (one misplaced column, and a missing comma).
FixFixed a problem with the "Total" column on AXLE volume exports, it was showing the total vehicles instead of total axles.
FixFixed "Start Date" and "Start Time" fields in all CSV exports. They only had a value of "0" or a "1" instead of the actual date and time as they should have.
FixMade all CSV exports consistent on how they export data (date/time should be in the same format, no dashes should be before or after the actual data begins/ends, and no blank line between days).
Changes in TrafficViewer Pro
PRN update
NewAll 3 PRN format variations should now be to the newest specifications. These are "daily" formats, not "monthly".
NewThe "PRN, Standard" format should allow importing into TRADAS software. (This needs to be tested and verified)
NewPRN exports can now export volume, class, or speed.
NewFor PRN options that will export multiple files, there is now a combobox that allows you to select the filename format. There are currently 16 formats. And any that have "" as part of it, will use the text you type in the "Custom Text" field as part of the filename.
NewFor the Hawaii PRN format, there is now the ability to select which direction is the primary direction (direction code E).
FixSome fixes and modifications to the PRN format exports.
Changes in TrafficViewer Pro
NewAdded "Export Directory" to the "Preferences" panel. Now you can have a default export directory that differs from your data directory if you choose.
NewThere is a new release of RetroCount (RK-1) firmware to correct a couple of bugs. Upgrading to the latest firmware (1.08) for RK-1 units is highly recommended.
FixDirectories are now remembered (so the open and save dialogs should come up in the same directory), also the default data directory should now be the one that is shown when opening or saving data for the first time.
FixDwells were not used in volume-only configurations, so when hoses had lots of echo on them the volume counts could be significantly higher than they should be. Dwells will now affect all types of setups, as they should.
FixFixed a bug with the report "Range Selection" window for volume-only configurations. The "Continue" and "Cancel" buttons were not positioned where they should have been.
Changes in TrafficViewer Pro
FixImproved processing on slower vehicles (under 30mph) that are slowing down as they are crossing road tubes. The algorithm was made slightly smarter to allow for more difference in speed between axles at lower speeds.
FixFixed a couple of typos in the hint text on the graphical timestamp display panel.
FixModified default FHWA scheme to make sure there is a dual axle for class 12 and class 13 in the second group of axles. This is to help prevent false class 12 and 13's in heavy traffic.
Changes in TrafficViewer Pro
NewAdded an operator timeout of 3 minutes to the software. If a unit is left connected, but no commands are sent to it within 3 minutes, then it will automatically disconnect.
FixFixed a problem with RoadRunner and RetroCount (RK-1) units not downloading data when connected to the computer with a USB-to-serial cable.
FixFixed a bug which, with some data or some hose spacings, may have caused an "access violation" message when processing the data after download.
FixFixed a small resource leak when closing TrafficViewer Pro while the "Data Setup" panel was open.
Changes in TrafficViewer Pro
NewA new RoadRunner firmware version is available (version 2.10). Added variable hardware dwells to the RoadRunner units in this version, these hardware dwells can be changed by clicking on "Configure Unit" and changing their values. The valid range is 1ms to 254ms. The default remains at 30ms. Note: Changing these lower will result in more data being stored in the RoadRunner unit causing it to run out of memory more quickly.
NewAdded PDF exporting.
NewAdded daily volume PRN exports. Currently the peak interval data is all zeros, and only volume PRN can be exported, more will be added in next release.
Changes in TrafficViewer Pro
FixFixed problems printing reports and problems exporting with Access Violations occuring. This was caused by some changes in how strings are used (strings are now mostly unicode to allow for multiple languages).
FixMade the font on the graphical display a little bigger.
Changes in TrafficViewer Pro
NewAdded internet-updating ability to easily keep TrafficViewer Pro up-to-date. You may now choose to turn on auto-updating of the software in "Preferences". You may also check manually by clicking on the "Check For Updates" button in "Preferences" or from the "Online" pulldown menu at the top of the window.
FixFixed a minor display issue in Log File viewer panel, the "Clear Log" button would not remain at the bottom of the panel if the panel was resized.
FixA couple of minor memory-leak bugs were fixed.
Changes in TrafficViewer Pro
NewBi-directional data will process properly. Some of the enhanced processing cannot be done on multiple directions, so data accuracy will be less, especially in high volume traffic (traffic where cars are passing over the hoses at the same time, or nearly the same time). We still recommend using one counter per lane/per direction for the best accuracy and as few problems as possible.
NewImproved/sped up processing in higher traffic areas of data for single-lane, single-direction data. Re-clustering now doesn't attempt to "split" a cluster in between certain axles, based on speed and distance, where axles are too close together to be two different vehicles. This will slightly speed up processing in heavy traffic. And, in theory, it could avoid some possible mis-classifications in cases where a truck doesn't fall into a classification -- it could help to avoid that truck being falsely classified as multiple vehicles.
NewEnhanced processing to handle missing hits better. Hits will be "added" where the software determines they are missing. In tests, this improved processing where missing hits were involved quite a bit. In real-world data this didn't amount to much of the data, but in some cases it improved classifications by about 1%.
NewInserted hits are visible on the graphical display window when looking through data.
FixThe display of cluster information in the graphical display panel is now shown in the appropriate measurement (English or Metric, based on what is set in the header). Previously all cluster info in that panel was shown in metric, no matter what was selected.
FixThe Vehicles list in the graphical display panel will now show all axle spacings separated by commas. Previously only the last axle spacing was shown.
FixGraphical display panel layout has changed slightly.
FixGraphical display panel's "Mouse Position" is now correct and accurate.
FixOn the graphical display panel, when scrolling through data the right edge of the graphical display got "dirty" (didn't stay white), it now will no longer collect "artficats" from scrolling through data.
FixFixed an issue with reports printed from some data files. Some files would start a report at a time other than 00:00 when "# of days" is used for the report range. This is fixed and now all reports that have a range entered in number of days will start at 00:00.
Changes in TrafficViewer Pro
FixImproved clustering algorithm when data has multiple directions. Clustering should do a much better job at paying attention to the direction that the cluster should be, and not falsely clustering in the wrong direction with the wrong mix of hits.
FixImproved processing to do more analysis on clusters in higher traffic situations. There should be fewer vehicles left unclassified in higher traffic, if "reclustering" is enabled (which is is by default).
FixFixed another fairly infrequent occurance while processing data: When a vehicle was tailgating another vehicle and the trailing vehicle was decelerating and traveling at a distance very close to the "max axle spacing", it was not clustering that tailgating vehicle. Those vehicles should now be clustered and used in the data.
FixFixed a bug in the clustering algorithm that, in rare cases of mixed-direction data or noisy data, could have caused the processing to skip up to an entire day of data.
FixPossible memory leak fixed in the "reclustering" section of processing the data.
Changes in TrafficViewer Pro
weekly update
NewRoadRunner units can now be connected and data downloaded in TrafficViewer Pro. (non-timestamp RoadRunner units are not supported, all version 2 units are supported)
NewRK-1 units can now be connected and data downloaded in TrafficViewer Pro.
NewAdded an "Abort" button to the download panel.
Changes in TrafficViewer Pro
weekly update
NewThe position and size of the main TrafficViewer Pro window is now remembered.
NewThe layout of "Preferences" changed around a bit, there are now tabs in it to allow for more options.
NewAdded default axle correction factors in "Preferences", instead of having to enter them each time.
FixChanged the "Online Documentation" menu option (in the "Help" pulldown menu at the top), to open up the latest work-in-progress version of the manual when opened in a beta version of the software.
FixWith a fresh new installation, the software was not creating a custom "schemes" diretory that was needed to create/save custom schemes. This directory is now created if it doesn't already exist, so custom schemes will now work.
FixFixed a "divide by zero" bug when using "unknown axle spacing" with axle correction factors of 0.
FixMade a minor tweak to how axles are grouped when there is a missing hit in the data. There is still a little more work to be done with missing hits.
Changes in TrafficViewer Pro
weekly update
NewTrafficViewer (.tvd) files can now be opened and processed. There are a few things to note: Multi-study .tvd files will not show multiple studies yet in TrafficViewer Pro, opening a tvd file with multi-directional data will not be handled well and should probably not be considered at this time, data will process classification data differently than it did in TrafficViewer data with little noise will have GREATLY improved accuracy and processing in TrafficViewer Pro.
FixFixed a bug in multi-day studies that would cause the quality meters to read higher than the should, also in "Additional Details" the "Total Axles" was a high value (the more days the more this number was wrong).
FixOn the Data Overview panel, the Class Summary and Speed Summary tables got a minor visual adjustment. The 3rd columns now have the same look as the 1st columns, since they are all "title" columns.
FixAs intended, panel positions should now remain in the same places they were last when the software was closed.
FixThe "Data Setup" panel that you see when downloading data or clicking on "Edit Header", did not have a label for the units used for "Hose Spacing". It will now show "inches" or "centimeters" depending on the measurement type chosen.
Changes in TrafficViewer Pro
NewFor volume-only, no classification, hose set-ups (set-ups with unknown spacing or with a median, or a short hose/long hose, etc.) now allow you to enter "axles per vehicle" or commonly referred to as "Axle Correction Factors". Previously it would just assume 2 axles per vehicle for those types of setups. When selecting a volume only setup, a button will be displayed on the data setup screen titled "Edit Axles/Vehicle" where you can edit this. And, as the FHWA recommends in section 4, chapter 4 of the "Traffic Monitoring Guide" you will be able to enter axle correction factors for each day of the week (as they may very greatly, especially on weekends).
NewProcessing has been completely reworked. It now "clusters" axles and handles those clusters. Now, ALMOST ALL aspects of the processing can be user-defined or modified. There are classification rules and rules for handling unclassified clusters. This will allow for COMPLETE customization by the user that wants to create their own classificaiton rules. These are very advanced features. These features can be accessed from "Advanced|Edit Classification Rules/Schemes" on the pulldown menu at the top of the application.
NewAdded the ability to drag and drop .tvp files onto TrafficViewer Pro and it will open the file.
NewClicking on .tvp files will now open them up in TrafficViewer Pro.
NewPanel positions are now remember from the last time the software was used. There are also two menu items "Cascade/Minimize Panels" and "Move Off-Screen Panels" on the "View" pulldown menu.
NewThe installer used for TrafficViewer Pro has been changed. This doesn't affect much, except a slightly smaller install and downloading upgrades manually and installing will no longer require uninstalling first.
NewAdded an identifier to the beginning of each file for TrafficViewerPro (so it can QUICKLY and EASILY tell if this file is really the desired type of file). For example the first few bytes of a data file could be: "TrafficViewerPro.Data", the first bytes of a scheme file could be: "TrafficViewerPro.Scheme", etc. This would allow us to even search a harddrive for data/scheme files and even if the extension matched, we would know if it was realy a trafficviewer pro file.
NewAdded change log to easily view changes since specified software versions and the ability to print it.
NewOverview window now show's the "Scheme" being used.
NewReports now show the Scheme used and it's scheme ID in case somebody needs to verify it's the exact scheme it should be.
NewClassification report was competely re-done to allow any number of classes, which will be determined by the scheme chosen. And the legend shows classification descriptions from the custom (or default) scheme selected.
NewAdded new quality meters for classification and channel hit differences.
NewAdded scheme list scanning to resolve scheme id conflicts. Old schemes should always keep the same id if somehow a new scheme file is copied into the same diretory with the same id.
NewUser is now prompted to save their data when attempting to download new data, open a file, or close the data overview with data that is unsaved or has been changed since opening it.
NewAll exports now have their own version tag, so when importing into an automated system this can always be checked to know if the export format has changed. The CSV field containing the export type and version is called "Export Version".
FixIn the counter setup screen after download, by default multiple directions will now come up opposite directions instead of the same directions.
FixFixed a bug causing the very last hit in the data (no matter how much data there was) to not get processed.
FixMade one more fix to the way non-US and/or non-standard date/time formats are handled and displayed.
FixAll processing is now done using metric numbers. Previously the tests used whatever measurement was selected, but that cause some rounding issues and other issues related to conversion that may show slight differences when flipping between Metric and English. The conversion now happens just before displaying the data, instead of at processing time. Now those should remain identical (so classes on the "edge" will remain the same class no matter what measurement setting you have when you view the data).
FixFixed a memory leak when closing the data overview window before closing the application.
FixWhen creating a new scheme in the Classification Rules panel, the new scheme is now set as the selected scheme instead of just showing up on the list somewhere.
FixFixed a bug in the scheme editor (Classification Rules panel) with the "Duplicate Rule" function when the rule had several sub-rules.
FixPanels will now move to the front when they are clicked on, instead of mousing over the title of the panel.
FixSeveral other fixes and enhancements were made.
Changes in TrafficViewer Pro
NewAdded a "debug" screen, which can be accessed via "View|Advanced|Debug Mode". Once it has been checked, any time you process data an additional window will show up with access to extra information and graphical/list views of timestamps and processing.
NewCleaned up pulldown menus: Added links to online manual, TrafficViewer Pro web page, and added several more menu items for various buttons in the software.
NewFilename now shows in the bottom left of reports.
FixFixed a problem with handling non-US standard Windows date/time formats. Previously it would display "not a valid date/time" when trying to open a file with a system setup with a different date/time format.
FixFixed the "Export" button that is located on the print preview screen; it now functions like the main export button (in the data overview panel).
Changes in TrafficViewer Pro
NewGreatly improved memory usage/processing speed with data over 1MB. Data is now processed in 1 day chunks.
NewUnit firmware can now be updated through TrafficViewerPro. It will auto-detect if an older version is being run.
NewAdded code for volume-only hose setups (i.e. short hose/long hose, median, etc.)
NewAdded *BETA* flag which the application can test for to store/load registry and other settings from/to a different location than an actual release (when one occurs).
NewAdded logging of some of the communications. This can be viewed by selecting "View" from the top menu and then choosing "Log File". It is mainly for troubleshooting purposes.
NewThe currently open or saved filename is now shown. It is displayed in the "Data Overview" window's title bar.
FixFixed a bug with "Auto Detect". If no device was connected "Auto Detect" would hang the application (it wouldn't allow it to be closed).
FixFixed a few bugs in data processing when there is only 1 axle or 1 hit in the data for a channel.
FixFixed a problem with data overview screen going blank if you click "Cancel" out of the "Edit Header" window.
FixFixed a bug that caused the firmware version to not show on reports or exports. It would just show "V" with nothing following it.
FixFixed a bug in exporting volume, class, and speed data that caused the last interval not to be exported.
FixFixed a minor bug in the volume export that had one extra quotation mark in "Total" columns label.
FixWhen exporting axle timestamps, the axles were being filtered before exporting. The list should now be the raw hose hits without filtering.
