Travel Demand Model & Data

The region's Travel Demand Model (TDM) is used to predict how travel patterns can change in the future and what mode (transit or automobile) may be used to complete these trips in Hampton Roads.  The TDM is used in a variety of ways:  forecast traffic volumes and patterns, project prioritization, analysis of candidates for the regional Long-Range Transportation Plan, support for the Congestion Management System, individual project studies, air quality conformity, and as-needed data requests.

The Virginia Department of Transportation (VDOT) and their consultants updated the regional TDM in 2020.  This updated model has the ability to forecast travel demand, including truck trips, by time of day; additionally, the updated model has an expanded model area to include the City of Franklin and Southampton County, updated Transportation Analysis Zone (TAZ) boundaries, network improvements, updated Non-Home-Based trip methodology, updated transit, mode choice, and toll components, and the ability to apply exploratory planning to investigate potential impacts of connected and automated vehicles on the transportation network.  These improvements can better replicate existing travel conditions and the level of detail and accuracy for forecasting.
