The Traffic Management Laboratory: system design

The Federal Highway Administration (FHWA) is developing the Traffic Management Laboratory (TML) as an environment in which traffic researchers and engineers can perform advanced research in advanced traffic management systems, from concept analyses to practical real-time control of traffic networks. The TML testbed enables the FHWA to evaluate new products, simulate monitoring and control of traffic networks using intelligent transportation systems (ITS) applications, and introduce traffic professionals to the emerging ITS technologies. The development of the Traffic Management Laboratory testbed has broken new ground in the area of systems design for distributed real-time simulation. By following an object-oriented approach and using the ObjecTime CASE tool, traffic engineers now have direct, automated traceability between the system design and the system implementation.
