Field applications of CORSIM: I-40 freeway design evaluation, Oklahoma City, OK

Simulation of traffic flow is an effective tool for evaluating alternative roadway designs, particularly in congested urban areas. CORSIM, a traffic simulation model with detailed representation of vehicles and their interactions, was used to study the performance of two alternatives for a freeway reconstruction project in Oklahoma City. The simulation identified problem areas in the two freeway design alternatives and assisted transportation professionals in selecting a preferred alternative.
