Abstract

CORSIM, which stands for CORridor SIMulation, is a microscopic simulation program created by the Federal Highway Administration for simulation of traffic operations on freeways and surface streets on a network basis. This paper presents 2 projects that were conducted in Florida using CORSIM. The first involved modifications to an existing interchange; this project used Highway Capacity Software (HCS) and CORSIM simultaneously to evaluate the interchange configuration. A comparison of the HCS and CORSIM results is presented. The second project involved a light-rail system that ran in the median of an existing surface street; this project used CORSIM to develop a model that can assess the traffic impact of light rail on the surface-street traffic. The method of how the light rail is modeled in CORSIM is also presented here. Due to space constraints, the detailed analysis of the light-rail CORSIM model is not included.
