Towards an online simulation of the city of delft

To cope with current and future demand for mobility the use of existing infrastructure has to be more efficient. To deal with the actual traffic situation, adaptive network control is required. The ¿Region Laboratory Delft¿ (a combined research institute of the Technical University Delft, the Ministry of Transport, road authorities and industry) collects on line data about the use of the infrastructure in the region of Delft. In addition, it also receives information about the actual status of the traffic control systems (ramp metering, speed control, lane use), weather conditions, and so on. The collected data are processed into meaningful information for traffic management (on-line), research and education (off-line). Traffic managers of different road authorities are informed about the actual traffic operations influenced by traffic control measures in an extensive common road network of all road authorities. The data are used to feed a microscopic online simulation model (MiOS) that predicts short term road use. This model is described in this contribution.
