THE PARAMICS-CM (PARALLEL MICROSCOPIC TRAFFIC SIMULATOR FOR CONGESTION MANAGEMENT) BEHAVIOURAL MODEL

The PARAMICS project has successfully demonstrated the application of discrete event simulation at a microscopic level to large road networks using parallel computers. The movement of some 200,000 vehicles on a 6000 link network can be simulated in multiple real time using a CRAY T3D with 256 processors. The PARAMICS-CM project now attempts to model advanced driver information systems installed over a wide area and the plausible behavioural response of drivers to certain Advanced Transport Telematics (ATT) devices. The paper introduces a number of simple data types which may be used to represent the information flowing between drivers and ATT devices. Behavioural response of drivers to such information is modelled using a formal rule language. Such rules may be invoked during the simulation to determine new routes for individual vehicles. Examples of rules used with the PARAMICS-CM simulator are presented and the parallel routeing algorithm developed for the project is described. For the covering abstract see IRRD 877041.
