A large number of toll road projects with a barrier toll collection system are currently being implemented in Russia. Therefore, it seems relevant to study the toll plaza as an element of the transport infrastructure. Insuffi cient attention to the issues of assessing current and predicted intensity on TPscan cause regular traffi c congestions on toll roads. The goal of this study is to build a simulation model that allows to evaluate the capacity of the toll collection point during the operation of the toll road at different traffi c fl ow rates, taking into account the ratio of different types of vehicles and user behavior errors. Visual observation materials are used, the research method is discrete-event simulation of PVP using AnyLogic software, processing of the results is performed in the statistical package R. The toll point (TP) the Western High-Speed Diameter toll road in St. Petersburg, Russia was considered as a case for the study.As a result was build simulation model of TP was developed, taking into account the traffi c specifi cs and user behavior errors. Conducted experiments established the peak traffi c intensities, when traffi c congestion begins to form at the TP, with different ratios of electronic toll collection usage. During the analysis, few cases of service time distribution were considered — from low to high traffi c intensities. Main conclusions of the study: -for the low intensity case, the results of the analysis showed the splitting of the total distribution of the service time into two distributions for different operating modes of toll lanes, — for high intensity, the infl uence of user behavior on service time distribution was revealed, — for each case, the parameters of the gamma laws of service time distribution were determined, — in case of insuffi cient throughput capacity, the TP stops working effi ciently, and service time distribution increases, regardless of the type of payment. Estimated peak hours of TP operation, when there is a potential for congestion at the TP were defi ned. Possible ways of further increase thetoll collection system throughput capacity for the TP were indicated. |
