• Abstract:
  The metropolitan transportation organizations in the eight largest metro regions of Texas and the Texas Department of Transportation jointly developed a process to investigate the congestion resulting from a range of investment levels. Part of this process, the Texas Metropolitan Mobility Plan, was the development of a set of performance measures. The measures are based on calculations from the long-range planning model output data. The same procedures used in air quality analyses are applied to congestion estimates. The measures are based on travel time information and comparisons with free-flow travel speeds. The Texas Congestion Index is a comparison of the travel condition during the peak period to the travel time in free flow. The procedures provide a method to estimated benefits from a range of operational treatments to provide a more robust set of performance measures. A set of spreadsheets and training materials are also available.
