    Accident prevention complex at passive level crossings

    In the Russian Federation, most railway accidents take place at passive level crossings. The majority of scientific papers on the topic of crossings deal with the improvement of active level crossings operation. At present, there is no effective way to improve safety at passive level crossings. The subject of the study is passive level crossings. The aim of the paper is to develop a set of preventive measures to avoid accidents at passive level crossings. The article describes the cases of traffic accidents at level crossings of the West Siberian railway, studies the scheme of passive level crossings and offers a schematic diagram of the accident prevention system at passive level crossings. The work algorithm of the accident prevention system at passive level crossings and the algorithm of giving the locomotive a notification of an emergency situation at passive level crossings are presented. Using the existing coding scheme of the train protection system as a transmission line for information about an emergency situation at a level crossing allows simplifying significantly the scheme of the developed system. The paper also calculates the maximum permissible time of occupation of the crossing by motor vehicles and the time of coding change in the automatic locomotive signaling system of continuous type. The proposed accident prevention system at passive level crossings does not require additional equipment to organize the communication channel and is cost-neutral. Equipping passive level crossings with this system will improve train safety, reduce the number of accidents and increase the efficiency of the railway transport complex in general.

    Analysis of the factors affecting the operation of a level crossing

    A level crossing is a system of interaction between rail and road transport. Traffic safety at level crossings is a priority in Russia. Despite the annual reduction in the number of level crossings and the modernization of existing level crossings, the number of accidents at level crossings, including fatalities, remains at the significant level. The subject of research is the factors affecting the safety of level crossings. The aim of the work is to identify the factors with the greatest affecting the operation of a level crossings in the Russian Federation. The research used: a generalized block diagram of a level crossing, a block diagram of factors affecting the operation of a level crossing, a prior analysis by the evaluation, calculation of the Kendall coefficient for individual groups of factors, sorting of factors according to the average assessment of experts. The article provides data on the number of road traffic accidents at level crossings in the Russian Federation for the period from 2005 to 2020, and the number of level crossings of different categories for 2020. It has been hypothesized that the main cause of accidents at level crossings is violation of the rules by vehicle drivers. The block diagram of factors affecting the operation of a level crossing based on the generalized block diagram of a level crossing. Factors affecting the operation of a level crossing are divided into four groups. The Kendall coefficient was calculated for individual groups of factors. Evaluation of the factors affecting the operation of a level crossing was implemented, according to the average assessment of the experts. This hypothesis was confirmed. Using of the results of this analysis will reduce the number of accidents at level crossings. The results can be used both in the modernization of existing level crossings and in the design of new level crossings.
