This chapter deals with the simulation of traffic flow through toll plazas (hereinafter referred to as TPs) on an intraurban toll road. Toll plazas (TPs) and their functioning parameters are the sources of traffic congestion risk on toll roads. Three types of TPs are considered: at the exit from the toll road; on the main course of the road; at the exit from the road before the regulated intersection. As a transport micro-simulation methodology, discrete-event simulation of TPs using AnyLogic software is used. Each TP simulation model takes into account the specifics of traffic and user behavior. At the end of the chapter, conclusions are offered on the main factors influencing traffic congestion for each of the TPs. Based on the data obtained from the simulations, recommendations were made to improve the performance of the TP and the traffic light facility, reducing the risks of congestion on the research objects.
