The development of a paramics Web external interface - PWeb

This paper describes the development of a Web external interface (PWeb) to link the dynamic traffic control simulator: Paramics with real traffic controllers. The Web-based interface is used to administrate the access of multiple controllers to paramics SNMP external interface during the simulation process, to prevent conflicts among the controllers and to improve the efficiency of the usage of paramics data input/output. A rule-based system and the connection to the database were developed to arrange the priority of the data to access paramics. The proposed Web interface has a potential to be applied in online simulations to calibrate paramics microscopic traffic simulation models.
