The document discusses various traffic simulation software that can be used for managing traffic at signalized intersections. It provides an overview of software tools like Aimsun, SIDRA, SUMO, and CORSIM that allow modeling traffic networks, signal timings, and evaluating performance measures. The document emphasizes that simulation software provide an understanding of traffic flow and interactions at intersections and are useful for testing design changes, signal optimization, and assessing different scenarios for improving traffic management.
