Abstract
Questions about the expediency of operating railway transport in an urban transport environment are considered. The positive and negative aspects of the passage of the railway through the urban environment are indicated both from the side of passenger railway traffic and from the side of the presence of intersections with road transport. Measures are given to reduce barriers in the organization of traffic at the intersection of road and rail traffic. On the basis of simulation-analytical modeling, software has been developed that is designed to calculate the integrated losses of society from the operation of single-level railway-road intersections in an urban environment with different traffic flow through the crossing.
It is proposed to determine the parameters of the qualitative transformation of the railway infrastructure in the city by comparing the economic losses and benefits of road users, which depend on the time of closing of railway crossings, the number of railway tracks and the number of car lanes, the intensity of vehicle traffic through the crossing and, as a consequence, the downtime of vehicles when passing trains. Schematic diagrams of dependence of costs (losses) and benefits of road users through railway-road intersections in one level are given. The analysis of railway crossings is carried out, the classification of public railway crossings according to the intensity of traffic of vehicles of the North Caucasian Railway and the city of Rostov-on-Don is given. A program is presented for calculating the integrated losses of society from the functioning of single-level railway-road intersections. The constructed functional dependencies, obtained by the simulation method, give high accuracy of the results obtained.
