The analysis of the existing traffic was carried out, a new scheme of traffic organization at the intersection of Mayakovsky street - Chkalov street was proposed, calculations of traffic light cycles at these intersections were carried out, taking into account the introduction of new traffic light objects. The results of the research will solve a number of problems of the road complex of the city of Shakhty to improve the transport and operational condition of the existing network of pub-lic roads of local importance and structures on them. To bring technical parameters and levels of engineering equipment of roads in compliance with the reached sizes of intensity of traffic.

The article analyzes the state of legislation as for provisions on the interaction of bodies and units of the National Police with local self governments in the field of public safety and order. The main directions of improving the legal basis of interaction of these bodies in this area are substantiated. One of the factors influencing the state of public safety and order in settlements is the degree of interaction of bodies and subdivisions of the National Police with local self-government bodies representing the respective territorial communities. According to the results of the study, the following areas of improvement of the legal basis for the interaction of bodies and units of the National Police with local self governments in the field of public safety and order were proposed: 1) standardization of the terms of cooperation of the specified bodies concerning maintenance of public safety and order in connection with the organization and carrying out of peaceful meetings and other mass actions; 2) consolidation of the recommended order of interaction between these bodies during the development and implementation of program documents on public safety and order; 3) determining the procedure for coordination by local self governments and the National Police in the field of coordination and control over the activities of public formations with regard of protection of public order and the state border; 4) legislative consolidation of the possibility of concluding agreements on interaction and coordination of activities by territorial police bodies and local self-government bodies; 5) determining the procedures for approval by territorial bodies (subdivisions) of the National Police of decisions of local self-government bodies on the issues of traffic organization and functioning of public transport. Separate elaboration requires regulatory regulation of relations arising in connection with the conduct of joint raids by representatives of local governments and the National Police and inspections of compliance with legislation in the field of landscaping, trade rules, etc. The search for optimal solutions to this problem should be the subject of further research.

Vessel traffic volume and vessel traffic service (VTS) operator workloads are increasing with the expansion of global maritime trade, contributing to marine accidents by causing difficulties in providing timely services. Therefore, it is essential to have sufficient VTS operators considering the vessel traffic volume and near-miss cases. However, no quantitative method for determining the optimal number of workstations, which is necessary for calculating the VTS operator staffing level, has yet been proposed. This paper proposes a new, microscopic approach for calculating the number of workstations from vessel trajectories and voice recording communication data between VTS operators and navigators. The vessel trajectory data are preprocessed to interpolate different intervals. The proposed method consists of three modules: Information services, navigational assistance services, and traffic organization service. The developed model was applied to the Yeosu VTS in Korea. Another workstation should be added to the current workstation based on the proposed method. The results showed that even without annual statistical data, a reasonable VTS operator staffing level could be calculated. The proposed approach helps prevent vessel accidents by providing timely services even if the vessel traffic is congested if VTS operators are deployed to a sufficient number of workstations.
