A ROUTE BASED VARIANT OF THE AIMSUN2 MICROSIMULATION MODEL

AIMSUN2 is a combined discrete-continuous simulator of road traffic. It can represent elements of the road system that change continuously during the simulation period as well as elements that change at discrete time intervals. AIMSUN2 is a microscopic road traffic simulator that models individual vehicles and their driver behavior. It distinguishes between different types of vehicles and drivers. AIMSUN2 also handles a variety of network geometries and can represent incidents, conflicting maneuvers, and so on. The purpose of this paper is to present a variant of AIMSUN2 that considers explicitly origin-destination matrices and the routes selected, and possibly modified, due to information that becomes available while the simulated trip is taking place. This new feature of the microsimulation model makes it suitable for application for a variety of intelligent transportation systems (ITS) applications that are related to temporal, time dependent route choice behavior by several classes of drivers. The results obtained with this variant of AIMSUN2 are illustrated in several pilot applications that demonstrate its suitability for temporal route choice simulation. The ouputs provided by AIMSUN2 include a continuous animated graphical representation of the traffic network performance, the reporting of various statistics, and enhanced data gathered by simulated detectors with the route information followed by each simulated vehicle with "within day" and day to day" modifications.
