[Go Back]

Here is a history list of what's changed recently in Tru-Traffic (formerly TS/PP-Draft) 10.0:

10.0.45.0 (2016.10.13)

Fix an error that could occur in calculating the Cumulative Average Speed (CAS) for the TT&D Report with certain preferences in units of measure for distance.

Fix an annoyance where the Offset Reference Point labels could omit the referenced phase number.

10.0.44.0 (2015.12.22)

Fix a quirk in optimizing phase sequences: if the yellow trap warning is displayed, the bands for all speed categories are temporarily displayed on the diagram.

10.0.43.0 (2015.11.16)

Fix an error in the Speed that could occur upon importing a Trip Log: the software could needlessly replace the instantaneous speed from the file with calculated, differential speed.

Fix an error that could occur in editing the splits when the adjusted cycle length is declared Uncoordinated — Implied.

10.0.42.0 (2015.10.28)

Fix an error that could occur in the phase sequence exported to the older, 5-file, UTDF 2.1 format when using Split-Lead/Split-Lag phasing.

Fix a quirk in the layout of the Network View that could artificially separate non-intersecting arteries beyond what's known from the geographic coordinates of the intersections.

10.0.41.0 (2015.6.22)

Fix an access violation that could occur in working with a trip log imported with no arterial timings diagram created.

Fix an error that could occur in managing an empty trip log – imported from a file with no valid GPS points.

10.0.40. (2015.5.18)

Fix an error that can occur in analyzing a trip log through an artery with a one-way subsection.

Avert an error that could occur closing Tru-Traffic while plots from trip logs are still in view.

At intersections with an uncoordinated, user-specified cycle length, rescale the splits whenever you change that user-specified cycle length.

10.0.39.0 (2015.4.15)

Fix an error that could occur in the offset reference point when exporting to UTDF 2.1 (the older, 5-file format) a file with multiple timing plans.

Fix an error that could occur synchronizing the clocks using the Synchronize Now button at a one-way intersection.

Fix an annoyance that can occur when viewing the Cycle Timer when the date on which you synchronized the clocks and today span a daylight savings time transition.

10.0.38.0 (2015.3.20)

Fix a labeling error that could occur at one-way intersections. The phase number that appears (in parentheses) in the offset reference point labels could be for a phase serving the side-street, in contradiction to the rest of the label.

10.0.37.0 (2015.2.5)

Fix an error in flipping the orientation of a diagram for a one-way artery. After flipping the diagram, the one-way designation applied to the opposite direction.

Avert a problem that could occur if you delete a trip log while it's still logging — that is, if you don't stop the logging before deleting the trip log.

10.0.34.0 (2014.11.10)

Fix an error that could occur in TT&D report's values for time spent above or below user-specified speeds. An interpolation error added, on average, 0.5 seconds for each downstream node along the artery.

Fix an error that could occur importing a trip log from a .csv file using the factory presets for a QStarz GPS receiver.

10.0.33.0 (2014.10.17)

Fix a divide by zero error that could occur when working with uncoordinated intersections.

In the comparative TT&D report, change the policy for computing the % difference: For the baseline, use the absolute value of the before values, instead of the actual before values, to avoid confusion where the before values are negative (e.g., a negative average Delay).

10.0.32.0 (2014.8.29)

When connected to NMEA GPS devices, tolerate a possible formatting error in the longitude.

When displaying labeled arrows along the approaches in the Network View for large networks, ensure the font size is big enough so that text is legible at least at the maximum zoom level.

Fix an error that could occur in analyzing a trip log (e.g., for the TT&D report) that has points recorded intermittently.

For composing formulas for user-defined columns in the TT&D report, make the node ID number accessible as a reference value. This can be useful for creating conditional rules that treat nodes differently depending their ID numbers.

10.0.29.0 (2014.5.14)

Fix an access violation that could occur in the (unlikely) case of an empty arterial diagram.

Fix a couple of errors that could occur when modifying the cross-street split, resulting in excessive arterial split.

10.0.28.0 (2014.4.17)

Fix an error that could occur in the green band along an artery with mixed cycle lengths.

Fix a problem in optimizing a limited group of intersections: In some cases intersections outside of the group could also be affected.

Fix an error that could occur in exporting T intersections to UTDF (in either format): the software could create the 4th leg for no good reason.

Avert an oddity where trip logs recorded by Tru-Traffic could get labeled as "imported."

Fix an KML format error that could occur in copying to the clipboard the geographic positions assigned to a specific intersection.

10.0.26.0 (2014.2.5)

Fix a bug that could allow "everything"-linked intersections to disagree on whether the offset references arterial phases or cross-street phases.

Fix a quirk that could effectively hide sections of the trip log trajectory on the arterial timings diagram.

When importing actuated splits from UTDF, if a phase is skipped because it's not actuated, automatically set the options to allow overrides of clearance time and minimum split without warnings for that phase.

10.0.22.0 (2013.10.21)

Fix a quirk in optimizing cycle lengths: when the performance of the various cycle lengths is displayed, the bands for all speed categories are temporarily displayed on the diagram.

Fix an error that could leave part of the Network View Properties dialog uninitialized: What to show along the approaches.

Fix, I hope, an error that could cause the software to freeze upon startup while displaying the splash screen.

Fix an annoyance in the Outline View where the option to break a selected link could remain disabled for no good reason.

Fix a quirk in the GPS View that could give an error if you entered a signal cycle start time of 12:00:00 AM.

Improve the reliability of creating a network by importing or pasting geographic positions -- ensure that geographic positions that are far apart don't get mistakenly assigned to a single intersection.

Fix an error where, in merging UTDF 2.1 files, the layout of the Network View could get mangled.

Fix a quirk in merging UTDF 2.1 files into a file with multiple timing plans. In some cases, the imported volumes could get assigned to all timing plans.

In importing trip logs from .csv files, extend the GPS Utility and USGlobalSat factory presets to more accurately identify the heading column, if any.

When creating a network by importing or pasting geographic positions, if there are only two nodes, then just connect them automatically and create the arterial diagrams.

10.0.18.0 (2013.4.23)

Fix an indexing error that could in highlighting or (en)disabling trip log points in the Details Table. If you sort the table on a column so the list is not chronological, then the item that you (un)check or select is not necessarily the point that gets altered.

Fix a quirk that could occur after pasting geographic positions into an empty Tru-Traffic window: When clicking the button automatically trace routes, be a bit more leneient in matching cross street names t numbers.

10.0.17.0 (2013.4.10)

Fix an error that could arise in the times when importing trip logs from table files (e.g., *.csv, *.tsv, etc.). If the times are given in the local time zone, and if a daylight savings time switch occurred after the dates recorded in the file and before you do the importing, then the imported times could be off by an hour.

Fix an error that could cause a divide by zero when you make a change to a diagram in the foreground while another diagram sits hidden, and not yet viewed, in the background.

When importing trip logs or geographic locations, show a warning when it appears that the wrong units or format is specified for the geographic coordinates.

If the signal cycle start time hasn't been set, assume a default master reference time of midnight.

Clarify in the help file and user's manual how the specified Band Width affects the width of the displayed band.

10.0.15.0 (2013.2.23)

Fix a problem that could occur importing long trip logs from GPS Utility files.

Let the file format preset for importing trip logs from GPS Utility files assume the time is UTC, not the local time zone.

Fix a quirk that could occur after pasting geographic positions into an empty Tru-Traffic window: When manually connecting dots to draw routes, in some cases, the next dot could be connected to the wrong end of the route.

Fix an annoyance when manually tracing routes (by clicking dots to connect them) after pasting geographic positions into an empty Tru-Traffic: If the balloon hint popped up for the dot, it would insulate part of the dot from accepting the mouse click.

10.0.14.0 (2013.2.15)

Fix a couple of errors that could creep in when using Flip Diagram Orientation. It seems that a few directional parameters, including the link curvature control points, could end up applying to the wrong direction of travel.

Fix an error that could occur parsing dates & times when importing trip logs from text tables.

Fix a couple of annoyances when pasting geographic positions into Tru-Traffic. If you've checked the box to "Set Names of Unnamed Intersections from Waypoints," then in some cases the Outline View or the Intersection Parameters dialog wouldn't show the new names until you refreshed.

10.0.13.0 (2013.2.5)

Fix an access violation that could occur when importing a UTDF file that's corrupted in certain ways.

Reduce potential crowding in the Network View. When showing labeled arrows along the approaches, use a smaller font if zoomed out such that there would be considerable overlap.

For importing trip logs from QStarz .csv files, include in the preset settings a column assignment for the time fraction (milliseconds) and improve the detection of the other columns.

Add preset settings for importing trip logs from GPS Utility files.

Add option to copy to the clipboard selected rows from the Trip Log Details Table.

10.0.12.0 (2013.1.10)

Fix a bug, new in ver. 10.0, that disabled the options to move or resize the background map in the Network View.

When clicking nodes to manually trace routes (after pasting geographic coordinates for the network into an empty Tru-Traffic), connect each newly added node to the nearest endpoint of the selected route, rather than to just the last endpoint or to the dragged-from endpoint.

10.0.11.0 (2012.12.13)

Fix an error that usually disabled the option to Split Artery into two Diagrams.

Fix an error importing geographic positions (and trip logs) from text table files (e.g., *.csv, *.tsv, etc.) with angles expressed in d:m:s format.

Fix an error, introduced in ver. 10.0.2.0, that could cause the directional summary pages of the TT & D report to show the wrong values in some of the columns.

In importing geographic positions or trip logs from tables, support yet a few more data types that I've recently encountered:

Add a section to the help file and the user's manual on Creating a Tru-Traffic Network starting from Locations in Google Earth.

10.0.10.0 (2012.12.10)

Fix an error that could occur in calculating the travel distance of a run from a multi-run Trip Log that has coarse resolution (i.e., has more than about 4 seconds between points).

Fix an error that could occur in displaying trip log times when the local time zone has no daylight savings time schedule.

In creating a network from a set of geographic locations (using the connect-the-dots window), assume locations with the same name apply to same intersection when node ID numbers aren't available.

Fix an error that could occur deleting an intersection while plots from trip logs along that artery are displayed.

Fix an error that could occur in printing an essentially empty arterial diagram.

Add option to quietly accept phasing for a specified movement that would normally trigger a warning about a yellow trap hazard.

10.0.7.0 (2012.9.19)

Fix an error that could occur in parsing trip logs from text tables -- some of the points could get skipped because the software thinks, incorrectly, that they're invalid.

When pasting, instead of importing, trip logs or geographic coordinates from text files, let the factory presets set the column delimiter to tab instead of comma.

Fix an oddity where, in some cases, changing the highlighting of trip log points in the Trip Log Details Table wouldn't affect the highlighting in the arterial diagram.

Include user-selected percentiles in the cumulative summaries of the TT&D report.

10.0.6.0 (2012.9.6)

Fix an error that prevented you from breaking a link in the Arterial Outline View.

10.0.4.0 (2012.8.6)

Fix a problem that could omit the band widths from the timings report or show instead band widths from the wrong band-speed category (Design Speed, Posted Speed Limit, Bus, Light Rail, or Bicycle).

In the various trip log selection dialogs (for setting, e.g., the speed, offset, or distance), let the user specify which statistic summarizes the selected trip logs: average, minimum, maximum, or various percentiles.

In calculating the directional weighting factors (based on per lane volumes) for optimization, add option to specify which statistic summarizes the selected intersections: average, minimum, maximum, or various percentiles.

10.0.3.0 (2012.7.13)

Fix a floating point error that could occur in merging a *.Dgm file as separate timing plans.

Fix a bug in the platoon-progression diagram where the queue discharge flow could extend outside the cycles assigned to that direction of travel.

Add options to view the Trip Log Properties, Details Table, or Playback by right-clicking the Trip Log in the Arterial Diagram, Network View, or Plot from Trip Log (e.g., Speed vs. Distance Plot).

10.0.0.0 (2012.6.27)

Initial release.
