Abstract

The article presents the results of using microscopic simulation modeling to optimize traffic on emergency sections of highways. It is shown that these areas are characterized not only by high rates of road traffic accidents, but also by large volumes of pollutant emissions from vehicle exhaust gases due to high traffic intensity, congestion, and imperfect road infrastructure. Based on the results of field studies, a simulation model of an emergency-hazardous section of the urban road network was developed, the adequacy of the model was proven, and virtual experiments were conducted. An option has been proposed to improve the environmental and traffic situation on the site by improving the technical means of organizing traffic. When implemented, because of an increase in throughput, there is a noticeable reduction in mass emissions of pollutants and an increase in the safety factor.
