Intelligent road transport flow management system: Basic ontology concepts

The work is aimed at solving the problem of traffic jams that occur at complex intersections. The problem is considered using the example of the city of Kyiv. However, it remains relevant for residents of many large cities. In this article here we consider the issues of creating ontology. It will later become the basis for forming the knowledge bases of several intelligent traffic management systems intended for traffic management at typical intersections in large cities. The scheme of operation of the system, which is being developed for the situational control of a complex of traffic lights under conditions of stochastic uncertainty, is provided, and the scheme of its operation is shown. The basic ontology concepts, which are primarily necessary for the development of intelligent systems and technologies for managing traffic flows in large cities, have been determined. Structured and formalized basic concepts of the "Road traffic" domain, such as: "Road infrastructure", "Traffic participants" and “Traffic flow”. Further research is planned to be directed to the formalization of the concepts "Traffic conditions", "Control systems" and "Decision models", which are required for coordinated control of traffic light complexes at typical intersections. As well as the connections "Road infrastructure" –"Road users", "Road infrastructure" –"Control systems", "Road infrastructure" –"Traffic conditions", "Road users" –"Traffic conditions", "Road users" –"Control systems" and "Traffic conditions" –"Control systems" will be formalized.
