ASSESSMENT OF THE ENVIRONMENTAL RISK OF ENVIRONMENTAL POLLUTION BY ROAD

Assessment of the quality of traffic management and design solutions in the field of traffic management in cities, complex systems for organizing the movement of cities with a population of more than 100 thousand people residents, temporary schemes of organization for the period of overlapping of significant sections of the street network is combined with the need to take into account a large amount of data to resolve contradictions of uncertainty of an objective and subjective nature. Taking into account the variety of factos to assess the effectiveness of the organization and management of traffic is possible only for small sections of the street network using advanced information technologies to improve the quality of automated traffic management through the implementation of optimization principles. The effectiveness of traffic management can be assessed by many factors that depend on its management. As an objective function of traffic management, a number of authors suggest using the following values: the number of road accidents, socio-economic damages from road accidents, the amount of harmful substances, the total travel time along the route, the number of stops per trip, the skip rate, the average delay of the crew per cycle, the average downtime, connection speed, traffic intensity, etc. The proposed calculations of the amount of the total risk and the average length of a person's life, which use basic normative data, allow to give a quantitative assessment of the danger of atmospheric air pollution. In this regard, environmental risk can be applied as an objective function of traffic management. As can be seen from the above results, both the environmental risk, and the time the car travels from one point to another, and fuel consumption are determined depending on the delays of vehicles in front of regulated intersections. Therefore, it is advisable to recommend as a target function for optimizing traffic management the value of the total time of vehicle delays in front of intersections of the urban street network in one cycle of regulation.
