A Simulation Laboratory for Evaluating Dynamic TraÆc Management Systems

Advanced TraÆc Management Systems (ATMS) and Advanced Traveler Information Systems (ATIS) are promising technologies for achieving eÆciency in the operation of transportation systems. This paper presents a simulation based laboratory environ-ment, MITSIMLab, designed for testing and evaluation of dynamic traÆc management systems. The core of MITSIMLab is a microscopic traÆc simulator (MITSIM) and a traÆc management simulator (TMS). MITSIM represents traÆc ows in the network, while TMS represents the traÆc management system under evaluation. An impor-tant feature of MITSIMLab is its ability to model ATMS/ATIS which generate traÆc controls and route guidance based on predicted traÆc conditions. A graphical user interface allows visualization of the simulation, including animation of vehicle move-ments. An ATIS case study with a realistic network is also presented to demonstrate the functionality of MITSIMLab
