METHODOLOGY FOR DETERMINING THE OPTIMAL PARAMETERS OF A PUBLIC TRANSPORT STOP POINT

Abstract

The article describes a study to determine the optimal parameters of a public transport stop. One of the directions of state policy in the field of transport services for the population in cities is the development and priority of public transport. Reducing the time delays of public transport can increase its attractiveness and increase the number of users. On a section of the road network with a stopping point for public transport, the length of the stopping area and the distance from the stopping point to the stop line of the regulated intersection have a significant impact on the delay time of individual and public transport. The aim of the study is to reduce the loss of time for road users by optimizing the parameters of a public transport stopping point based on the established dependencies of vehicle delay time on the length of the stopping area and the distance from the stop point to the stop line of the regulated intersection. The work uses the methods of simulation and mathematical modeling, the theory of traffic flows, methods of field observation and statistical analysis. In the theoretical part of the study, the processes of movement of traffic flows of individual and public transport are described, the hypothesis of the study on the type of mathematical models of the delay time of individual and public transport from the parameters of the stopping point (the length of the stopping area and the distance to the stop line of the regulated intersection) and the objective function are defined. To conduct experimental studies, simulation modeling of the movement of traffic flows is used. Mathematical models have been developed for the influence of the length of the stopping area and the distance of the stopping point from the stop line of the regulated intersection on the average delay time of individual and public transport at different traffic intensity of individual and public transport, which are described by a power function. On the basis of the results obtained, a method for determining the optimal parameters of the stopping point has been developed. Using the methodology on one section of the road network with a public transport stop, it is possible to reduce time delays by 10%. The scientific novelty of the study lies in establishing the dependence of the delay time of individual and public transport on the parameters of the stopping point (the length of the stopping area and the distance of the stopping point from the stop line of the regulated intersection). Further research will be aimed at studying the influence of the stopping point parameters on the choice of the optimal priority method for buses when passing regulated intersections due to the adaptive control of traffic light objects.
