Qualitative assessment of the composition of the traffic flow

Abstract

The car park is growing at a rapid pace every year. According to the official statistics of the traffic police service, on the roads of the Russian Federation, mainly passenger vehicles prevail, accounting for 80-90% of the total number of cars. Passenger vehicles include a large number of various vehicles that differ from each other in design and technical parameters, with an overall length of 2.5 m to 5.8 m. The difference in overall length affects the value of the dynamic dimension and, accordingly, the throughput of the road network, which requires constant monitoring and improvement, especially when using technical traffic control systems. It is necessary to consider the influence of the main parameters of the traffic flow when calculating the saturation flow at an intersection controlled by a traffic light object.
