Measuring Congestion Relief Benefits

This project seeks a nationally-consistent method for predicting congestion-relief benefits of proposed transit capacity expansion projects. The performance of best-practice forecasting procedures will be tested in selected case study areas to determine (a) the accuracy with which existing procedures predict current traffic volumes and (b) the reasonableness of forecasts of traffic volumes and highway speeds for a major transit alternative that reduces the number of vehicle trips assigned to the current highway network. In evaluating and rating proposed New Starts projects, the Federal Transit Administration (FTA) is required to consider mobility improvements, including reduction in highway travel times resulting from a transit improvement. The U.S. Department of Transportation (USDOT) has not yet been able to develop methodologies capable of making reliable, nationally-consistent estimates of project-specific benefits related to congestion relief. This research will examine and test existing forecasting methods and identify those suitable for national application. It will identify a nationally-consistent approach to measure the highway travel time savings from transit improvements and produce a final report.
