ASSESSMENT OF THE UNEVENNESS OF THE MOVEMENT OF VEHICLES IN THE PLACES OF SEPARATION OF TRAFFIC FLOWS

Abstract

The movement of vehicles in the places of separation of traffic flows is analyzed. The high-speed mode of movement of vehicles along traffic lanes at a regulated intersection in the places of traffic flow separation has been determined. It is recorded that the number of formed “bundles” increases in the places of separation of transport flows. The movement of the formed “packs” of moving cars determines the speed mode of vehicles. The experiment showed that the speed of movement along the lanes is different. In a lane with a large number of formed “bundles”, the speed of cars is less than in a lane with a smaller number of “bundles”. It is established that the presence of “bundles”, especially in the areas of separation of traffic flows, leads to a large variation in the range of changes in the speed of vehicles at the intersection. The highest value of the speed mode of vehicles when driving on the experimental section is within 15-20 km/h, and the lowest is less than 5 km/h. Purpose – determination of the factors influencing the change in the speed regime of vehicles in the places of separation of traffic flows. Methodology statistical methods of processing a full-scale experiment were used in the work. Results: the ranges of changes in the speed of vehicles in places where traffic flows are separated by lanes and the reasons for their changes are determined. Practical implications: the obtained results should be used in the development of measures to ensure road safety in places of separation of traffic flows and the organization of traffic at intersections.
