IMPROVEMENT IN THE FUNCTIONING OF TRANSPORT NETWORK OF URBAN PASSENGER TRANSPORT BY USING AUTOMATION OF OPTIMAL ROLLING STOCK SELECTION MODEL

The article identified and analyzed the main factors that affect the organization of the efficient functioning of the transport network of urban passenger transport. Automation of selecting the optimal model of rolling stock is an important task to improve the efficiency of the transport network functioning.

It is noted that the type of vehicles serving a specific route, as well as the configuration of the route network, largely affects the overall cost of the transport system. In this regard, we reviewed the optimization mathematical model of two-level choice of rolling stock required capacity, which can be used for different transport networks, of in order to provide the most complete and qualitative satisfaction of needs of the population in the necessary traffic and quality of service, in conjunction with the economic feasibility. The concept of «economic feasibility» includes increased productivity, profit margins and profitability of transport companies, minimizing the total social costs associated with the operation of the transport system. Cost structure used in this model – passenger and operating costs. The model assumes that the passengers are selected from all the possible routes connecting any two nodes in the public transport network. It is assumed that the system has a limited bandwidth and, therefore, travel time increases proportionally to the number of passengers.

The methods of selecting the optimal type of rolling stock presented in the article, allow to reduce operating costs, but for effective implementation coordinated work of all participants in the transportation process is necessary.
