Generating Driver Population for the Microscopic Simulation Model (CORSIM)

Abstract

CORSIM (CORridor SIMulator), an interval- based simulation model, was developed by the Federal Highway Administration (FHWA) to analyze traffic operations. In CORSIM, each ve hicle is a distinct object that moves every second, whose kinematic properties (speed, acceleration, and jerk) as well as its status (queued, moving, lane changing) are updated every second. Thus, driving behavior on roadways reflecting real- world traffic operations can be simulated. This paper suggests that the driving behavior repre sented by speed distributions over different driver types should be built in CORSIM to reflect more realistic patterns of driving behavior. The impact of the driver distribution to freeway capacity is demonstrated through simulation analysis.
