Title:

Sensitivity Testing and Assessment of an Integrated Regional Travel Demand and Traffic Microsimulation Model

Abstract:

Most current travel demand forecasting models are not sufficiently sensitive to the dynamic interplay between travel behavior and network conditions by detailed time-of-day, and as a result are unable to reasonably represent the effects of transportation policies such as variable road pricing and travel demand management strategies. The SHRP 2 C10A project was initiated in order to make operational a dynamic integrated model system that realistically captures the complex interplay between demand and supply in order to provide more reasonable representations of the effects of transportation policies. This paper documents the preliminary results and qualitative interpretation of a set of systematic sensitivity tests of the model’s enhanced temporal and spatial structure and policy capabilities. The sensitivity tests described in this paper cover a broad range of policy options including pricing, travel demand management, and operational strategies that were evaluated using the Burlington implementation of the model system. The model system demonstrated sensitivities to the pricing and travel demand management strategies that appeared reasonable in terms of the direction and magnitude of change at both aggregate and disaggregate temporal and spatial resolutions. However, the model system sensitivities to the operational improvements, specifically signal progression along three key regional corridors, were not as robust or conclusive.
