With the emergence of Intelligent Transportation Systems (ITS), new efficient systems are needed for the real-time operation of Traffic Management Centers. Their role is to develop strategies to improve traffic conditions, decrease congestion, maximize safety, minimize pollution, etc.
For these systems to be effective, the generated strategies should be proactive (i.e. based on predicted traffic conditions) as opposed to reactive, in order to avoid many undesirable effects such as overreaction.
DynaMIT (Dynamic Network Assignment for the Management of Information to Travelers) is a distributed system of models that provides traffic predictions and travel guidance. DynaMIT is designed to operate in real time, accept real-time surveillance data, and estimate and predict travel demand. The system also incorporates different driver classes and their behavior, estimates current network conditions, predicts future traffic conditions, interfaces with the traffic control system, and generates route guidance consistent with the predicted traffic conditions. It is designed to make departure time, mode and route recommendations for a variety of information systems and information dissemination strategies. DynaMIT is implemented in a distributed environment, under the CORBA protocol.
The overall design of DynaMIT will be presented. The main models and algorithms will be described, and their interactions will be commented. Real-Time issues and system evaluation will also be discussed.
