Development of Practical Software for Micro Traffic Flow Petri Net Simulator

[Abstract] Recently demand for microscopic traffic flow simulators is increasing both from changes of problem situations we encounter in transportation planning and intensity of public involvement (PI) movement in public planning. We have been developing a new type simulator based on Coloured Timed Petri Net. This type simulator has potential to be put into practical use as PI support system. In this paper we present a more practically strengthened prototype system on Windows-OS platform and show its active supportability for development of individual simulations and accountability of their usage to a wide range of people involved. We demonstrate especially how newly developed menus such as drawing traffic-flow-net, tracing token behaviors on the net, making the individual places/transitions/arcs visible or invisible by selection, work and improve readability of Petri net description for microscopic traffic flows and contribute to putting the simulator into practical usage.
