SetupTru-Traffic10.msi 12.6 Installs the current version of Tru-Traffic (formerly TS/PP-Draft) (10.0.45.0)
This includes the updated User's Manual, which is also available as a separate download.
By default, this installs per user. On Windows 7 and Vista, if group policies permit, this default permits a user with limited privileges to install the software for just the user, without affecting the whole system or any other users, and that same user can apply any future updates. If you prefer to install per machine (for all users), use the following command at a command prompt:
msiexec.exe /i SetupTru-Traffic10.msi ALLUSERS=1
If you downloaded and installed, prior to 2011/12/23, the "Emissions using CMEM for Vehicle Category 4 rev2.URC" set of user-defined columns for the TT&D Report, then you'll want to download again and reinstall (removing the previous set of columns), as a recent revision fixes an error in the NOx emissions.

CumulativeAvgSpeedLOS_mph.URC

CumulativeAvgSpeedLOS_kph.URC
0.002 A set of user-defined columns for the Travel Time & Delay report. Created and donated by Mark Taylor of Utah DOT (and edited somewhat by me), these give the
  • Level-of-service (LOS) based on the average per-intersection delay (Exhibit 16-2 in the 2000 Highway Capacity Manual (HCM)) for the corridor being evaluated, and
  • Cumulative Urban Street LOS by Class based on the average speed for the entire artery (Exhibit 15-2 2000 HCM).

In both cases, "1" indicates LOS A, "2" indicates LOS B, "3" indicates LOS C, "4" indicates LOS D, "5" indicates LOS E, and "6" indicates LOS F.

Use the "_mph" file if you measure distances in feet and speed in miles per hour.
Use the "_kph" file if you measure distances in meters and speed in kilometers per hour.

These have been updated with the release of version 8.0 to take advantage of the new option to show the LOS as a letter (A, B, C, ...) instead of a number (and to implement a minor correction to the formula). The updated files are backward compatible with version 7.0, but that version will continue to report the LOS as a number. The formulas for SpeedLOS and CSpeedLOS were further tweaked 2009/4/5 to

  1. better conform to the intent of Exhibit 15-2 in the HCM2000 for Urban Street Class IV, and
  2. to avert a numerical roundoff quirk that can cause the average LOS of two trip logs with LOS A to not be LOS A.

You'll need to download and reinstall these to get the new feature and the formula tweak. Before reinstalling, you can remove the existing five columns DperInt, LOSDelay, CDS, SpeedLOS, and CSpeedLOS by selecting them all (using Ctrl or Shift clicks) and clicking the Delete button.

To install these new columns, use View: Preferences: Layout: T T & D Report: Report Columns, then right-click on the list of columns and choose "Merge user-defined columns...."

Emissions using CMEM for Vehicle Category 4 rev2.URC 0.027 (Updated 2011/12/23 to fix an error in the NOx emissions. See note below on reinstalling.).
A set of user-defined columns for the version 9.0 and above (only) Travel Time & Delay Report to give the
  • Emissions (g/hr) of CO, HC, NOx, and (in kg/hr) CO2, and
  • Fuel Consumption (L/hr)

based on the instantaneous speed and acceleration of the Trip Logs, using the formulas from the Comprehensive Modal Emissions Model (CMEM) NCHRP Project 25-11, and the coefficients from Table 4.4 for Vehicle Technology Category #4: "3-way Catalyst, FI, >50K miles, low power/weight".
You may want to use this set of formulas as merely a template, substituting the coefficients for a Vehicle Technology Category more applicable to your area. Better yet, you may want to replicate these formulas with coefficients for multiple Vehicle Technology Categories and perform a weighted average of the results based on the percentage of vehicles of different categories.

The formulas giving emissions in g/hr or kg/hr depend on the through volume, so your .Dgm file must have the arterial volumes entered. If you prefer the emissions reported in g/run or g/veh, or if you don't have the through volumes entered, then please see the forum topic here.

Note that the results of these formulas give the consumption & emissions only for the through movement — the movement in the trip logs — and they are accurate only to the extent that your trip logs are a representative sample of that movement's hourly volume. For example, if your trip logs tend to sample only the first vehicle in the queue, then these formulas will give biased results accordingly, and you'll want to take that into consideration when interpreting the results.

To install these new columns, use one (and only one!) of the following methods:

  • File: Open and change the file type to "User-defined TT&D Report Columns (*.URC)",
  • Drag the *.URC file into the Tru-Traffic main window (its desktop),
  • Double click on the *.URC file in Windows Explorer, or
  • View: Preferences: Layout: T T & D Report: Report Columns, then right-click on the list of columns and choose "Merge user-defined columns...."

Note on Reinstalling: If you're downloading and installing again to fix the error in the NOx emissions error prior to 2011/12/23, then be sure to first remove the previously installed set of user-defined columns related to the CMEM emissions. The set starts with the (probably hidden) column "AIMS" and ends with the (possibly hidden) column "CMEM_VC4_FC".

  • Navigate to View: Preferences: Layout: T T & D Report: Report Columns.
  • Scroll the list of columns as needed to click and highlight the column "AIMS".
  • Hold down the <Shift> key, and scroll the list of columns as needed to Shift-click the column "CMEM_VC4_FC" to highlight the entire set.
  • Click the Delete icon along the right edge of the window.
  • Now you can install the revised set of columns as described above.
FuelConsumption&Emissions_mph.URC

FuelConsumption&Emissions_kph.URC
0.002 A set of user-defined columns for the Travel Time & Delay report to give the
  • Fuel Consumption based on the number of stops, delay, travel distance, free-flow speed (or design speed), and through volume, using University of Florida model with TRANSYT7F-10 default coefficients,
  • Fuel Consumption based on the number of stops, delay, travel distance, free-flow speed (or design speed), and through volume, using Penic & Upchurch model with TRANSYT7F-10 default coefficients, and
  • Carbon Monoxide, Nitrogen Oxides, and Volatile Oxygen Compounds Emissions (g/hr) using the Synchro 7 formula (from unpublished Oak Ridge National Labs letter to Federal Highway Administration) and each of the above two Fuel Consumption models.

Use the "_mph" file if you measure distances in feet and speed in miles per hour. The Fuel Consumption is given in gal/hr.
Use the "_kph" file if you measure distances in meters and speed in kilometers per hour. The Fuel Consumption is given in L/hr.

These formulas depend on the through volume, so your .Dgm file must have the arterial volumes entered.

Note that the results of these formulas give the consumption & emissions only for the through movement — the movement in the trip logs — and they are accurate only to the extent that your trip logs are a representative sample of that movement's hourly volume. For example, if your trip logs tend to sample only the first vehicle in the queue, then these formulas will give biased results accordingly, and you'll want to take that into consideration when interpreting the results.

OCTA CSPI v2.URC 0.005 (Updated 2013/11/20) A set of user-defined columns for the Travel Time & Delay Report to give the Corridor Synchronization Performance Index (CSPI) from the Orange County Transportation Authority (OCTA), created and donated by Jonathan Yee, DKS Associates (now with Iteris, Inc.), Santa Ana, CA (and now of , with assistance and editing from me, based on a specification provided by Ron Keith of OCTA in the user's forum here and here.

These formulas were updated 2013/11/20 based on a phone conversation with Ron Keith, Jonathan Yee, Rock Miller, and Greg Bullock. The speed score uses a "linearized" scale in the sense that the lowest score is 7.5, instead of 8, so that the entire set of (speed,score) pairs are co-linear (i.e., they all fall on a single, straight line). Also, the averaging policy now reflects Rock Miller's preference to calculate the CSPI score for each run, then average the scores together. Previously, the policy computed the average stops, speeds, etc. of all runs, then calculated the CSPI score based on those averages. A topic in user's forum discusses some of the implications.

You'll need at least ver. 8.0.0.71 or ver. 9.0.0.9 or above to get correct results for the CSPI in the details tables, as those versions fix a bug that could corrupt the results for an individual trip log depending on what type of averaging option is specified for a user-defined column.

To install these new columns in ver. 8.0, use View: Preferences: Layout: T T & D Report: Report Columns, then right-click on the list of columns and choose "Merge user-defined columns...." To install these new columns in ver. 9.0 or above, use one (and only one!) of the following methods:

  • File: Open and change the file type to "User-defined TT&D Report Columns (*.URC)",
  • Drag the *.URC file into the Tru-Traffic main window (its desktop),
  • Double click on the *.URC file in Windows Explorer, or
  • View: Preferences: Layout: T T & D Report: Report Columns, then right-click on the list of columns and choose "Merge user-defined columns...."

Band Action.odp 0.03

A slideshow to help explain the Band Action in Tru-Traffic. Some simple animation during the slide transitions helps illustrate what's going on. There are some momentary pauses within the slide transitions, and there are some indefinite pauses once the transitions have finished. To proceed after the indefinite pauses, you'll need to click the space bar or the right-arrow key, but first you'll want to wait a few seconds to make sure it's not just sitting at a momentary pause — otherwise, you'll jump to the next slide before the current one has finished playing.

To view the slideshow, you may need to install OpenOffice.org. As I understand, versions of Powerpoint as of 2010 are able to read ODF documents — the Open Document Format. But if you don't have a new enough version of Powerpoint, you can view this by installing and using OpenOffice.org.
