Street-crossing Simulation in Real Environments- A Case Study

Abstract:- The paper describes a discrete-event simulation model designed to study and optimize a very busy and problematic crossing located at Coimbra, a Portuguese town. The model takes into account a lot of details, namely arriving and crossing times, possible delays and traffic light control. Some common-sense simplifications were made. BestFit and Extend software were used. The model proved to fit reality constraints in every aspect. Some what-if situations have then been tested. However, the conclusion is, perhaps, surprising. Key-Words:- Discrete-event simulation; optimization; traffic light.
