Abstract

The authors investigated the methods of structural-parametric synthesis, mathematical modeling and optimal control of transport networks from the position of the system analysis. The goals of ensuring the transport infrastructure safety with the positions of the transport network optimal load are determined especially in case of emergency situations. The paper describes the requirements for the development of a mathematical model of the transport network loading. A large number of studies on the transport network load is carried out in the environment of the “ITSGIS” intelligent transport geographic information system and was aimed at the development of the algorithm for automatic detection of emergency situations and congestion. The emergency situation types are characterized by its location, i.e. its coordinates on the electronic map. The emergency time is considered from various positions, such as time of occurrence, normative and actual time of elimination. The geofences of an emergency situation influence are divided into areas of direct and indirect emergency situation influence on transport processes and transport infrastructure objects. On the basis of the constructed models developed management methods of transport network loading and emergency situations analysis, including the collection and processing of raw data, the emergency situations determination and their characteristics, the optimal response strategy choice, the performance of management functions.
