• 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...."

• 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• Carbon Monoxide, Nitrogen Oxides, and Volatile Oxygen Compounds Emissions (g/hr) using the Synchro 7 formula (from unpublished Oak Ridge National Labs letter to Federal Highway Administration) and each of the above two Fuel Consumption models.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.

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...."

A slideshow to help explain the Band Action in Tru-Traffic TS/PP. 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'll probably need to install OpenOffice.org. A few years ago (in 2008), I tried to export it as a Powerpoint slideshow, but the slide transitions got goofed up. I believe the current version (as of 2010) of Powerpoint (and the current version of MS Office generally) is supposed to be able to read ODF documents — the Open Document Format — but I haven't tried it to know whether it works well enough. So for now, the only proven way to view this is by actually installing and using OpenOffice.org. If you try it with a current version of Powerpoint, I'd be interested to hear whether it works or not.
