The article is dedicated to the investigation of internal and external factors affecting traffic safety of railway transport, including researching and solving ever-present issue of investigating, reducing and eliminating human factors, emergency situations and other impacts through complex methods and means. The technical state of wagons, one of the important components for traffic safety in railway transport, methods and means of detecting faults during their diagnostics, and making right decisions according to the situation are investigated. Diagnostics of the state of wagons is carried out through the method of remote measurement at measuring points installed at certain distances with a certain rule. At measuring points, the temperatures of tire boxes are investigated according to the normal limits, and risk status is assessed according to the comparison results. Accuracy and stability of diagnostics are very important for safe operation. In order to make right decisions, assessment of measurement errors of temperature factors, performing self-monitoring and correction, execution of the algorithm based on repeated measurements and points, carrying out comparison with norm limits, and making decisions provided that they are confirmed are presented. Based on Fuzzy Logic in Matlab environment, assessment of processing risks and suitable combinations are presented.

An intelligent system that monitors the speed and condition of a moving object is designed to reduce the risk of potential threats that may arise with autonomous decision-making capabilities depending on the situation and exchange information with databases via remote network sensors. Risk assessment based on information obtained from stationary metering stations installed at intersections and control crossings, object characteristics parameters and side-effect parameters, alerting the central management system based on the results, and making decisions on regulating the speed of the facility, depending on the level of danger and whether the decision is approved by the center, providing information about the facility on the board, sending alerts to security systems at intersections, and identifying opportunities for change by influencing decisions based on risks The characteristic technical parameters of the inflated object depend on internal and external factors and making appropriate decisions according to the risk assessment, etc. information on processes, monitoring, and control. Monitoring of working conditions with the participation of the remote control wireless sensor network in the central control room.
