Optimization of traffic flows to increase the capacity of urban unsignalized junctions

Abstract

Regular studies of traffic flows allow obtaining the actual parameters of the vehicle movement. Field observations using unmanned aerial vehicles help to optimize the research due to the wide capture field of the video camera, which allows comprehensively assessing traffic flows simultaneously utilizing all approaches to the intersection. When designing a road network, it is necessary to determine the capacity of all its elements. The characteristic elements are unsignalized intersections and junctions, the capacity of which largely depends on the intensity of the main and secondary directions, the behavior of drivers and the adoption by drivers of intervals between cars of the main traffic flow when entering the intersection.
