Traffic Modeling — Various Projects

GBA’s traffic engineers use state-of-the-art technology to create sophisticated computer models that predict future traffic conditions and help our clients determine the best possible solution to potentially serious traffic problems. The CORSIM traffic model simulates anticipated traffic operations and allows the user to consider numerous improvement alternatives for a wide range of traffic conditions. CORSIM software is used to analyze individual intersections to determine delays, optimum speeds, fuel consumption, and vehicle emission rates under various geometric and traffic control conditions. It is also used to analyze complex interchanges and entire corridors to determine geometric improvements to best accommodate anticipated traffic volumes. GBA has used this program to assist many of our clients.

GBA also assists clients using computerized traffic demand models such as TModel2, MinuTP and QRS. Using these models, GBA traffic engineers have worked with clients to determine future growth in area-wide traffic volumes as part of comprehensive land development impact studies. GBA is currently developing community-wide traffic demand models to assist local governments in determining future traffic volumes and improvement needs.
