Regional Travel Demand Model

The travel demand model is an analytical tool used for regional transportation planning.  WCOG deploys the conventional four-step trips-based travel demand model process comprised of trip generation, trip distribution, mode choice and route assignment.

The model is used to develop “scenarios” that incorporates a proposed change to the transportation network and/or land use and analyzes the impact of that change in vehicle miles traveled, vehicle hours of travel, origin-destination analyses, traffic volumes and travel times.  Additionally, model data are typically applied to further analytical tools such as microsimulation, activities-based modelling, environmental and air quality simulations.

The current travel demand model analyses for WCOG’s current long-range transportation plan can be viewed in Way to Go, Whatcom.
