Linking activity-based travel demand models and traffic assignment: A Flemish case study

Abstract

A custom agent-based simulation framework is developed that combines the fields of traffic demand modeling and traffic assignment, applied to the region of Flanders (Belgium). The framework uses an activity-based approach to model traffic demand and an assignment module that is linked to the traffic demand module. Activity data for the framework is provided by a large scale survey, conducted on 2500 households in the study area. The agent-based simulation model consists of over six million agents, one for each inhabitant, to represent the Flemish population. The simulation of the linked traffic demand and assignment models results in traffic intensities for the links in the Flemish transportation network.
