Improving Our Understanding of How Highway Congestion and Pricing Affect Travel Demand

TRB SHRP2 Program

Overview

This project was carried out to review and advance the state of the practice in modeling the effects of highway congestion and highway pricing on travelers decisions, including the choice of facility, choice of route, choice of mode and choice of departure. Important findings are related on how demographic characteristics, auto occupancy, carpooling, value of travel time, value of reliability and travel distance affect the willingness to pay, VOT, and VOR. The report includes mathematical descriptions of the full range of highway user behavioral responses to congestion, travel time reliability, and pricing. The descriptions included in the report were achieved by mining existing data sets. The report estimates a series of nine utility equations, progressively adding variables of interest. The report presents useful information related to the future of modeling and how reliability can be efficiently incorporated to existing and new models.
