Simulation based traffic information system.

There is a growing need for improvement in the efficiency of urban traffic in order to ensure the sustainability of modern cities. It is now recognized that this can be achieved through the coordinated improvement of traffic monitoring and management schemes in traffic control centers and the provision of information services for ordinary road users. The real-time (on-line) simulation can have an important role in these schemes. In this paper the concept of microscopic on-line traffic simulation is presented together with potential applications. As an application real-time traffic information service through Internet is presented. Also the use of on-line simulation for traffic control purposes is discussed. A prototype system is demonstrated based on HUTSIM urban traffic simulator, DIME distributed memory server and SCOOT- urban traffic control system. The presented methodology can be applied to other UTC-systems if proper real-time data is available. For the covering abstract see ITRD E114174.
