Performance Enhancement Module

The Performance Enhancement Module identifies transit capacity investment to improve operating performance beyond the asset expansion module. The module identifies investments based on the national average vehicle operating speed. In the NTD, average rail operating speed exceeds the average bus operating speed, and this principle is employed along with the MPO forecasts to identify rail investments required to increase system speed and reduce vehicle utilization. The module makes investments required to improve transit operating speed in urban areas with the lowest speeds and to reduce vehicle utilization rates for the most crowded transit operators. The module estimates the investment levels required to allow systems falling below the minimum operating speed threshold or above the maximum vehicle utilization threshold to add new transit capacity until these threshold values are attained.

Earlier versions of TERM also contained a New Starts Pipeline submodule within the Performance Enhancements module. However, this feature is no longer utilized.
