A microscopic traffic simulation model for the evaluation of toll station systems

The work focuses on the analysis of mixed toll stations with different toll collection systems. A new microscopic simulation model for the analysis of vehicular flow at a toll plaza system is presented. It is able to represent the traffic demand/supply interaction and the effects on traffic induced by the geometric and functional characteristics of the infrastructure. It allows one to observe situations in which, because of the limited capacity of manual toll gates, queues spill back interfering and reducing electronic toll collection gates capacities. The model can be a useful operational tool for support planning activities of toll plaza systems, in order to reach optimal operational efficiency levels.
