Abstract
Dynamic traffic re-routing as a method of reducing the congestion level of road network elements
Highlights
The efficient use of the transport city infrastructure is mostly determined by the existence and operation of intelligent transport systems (ITS)
At the same time the application of this method is determined to a certain extent by the architecture of the city's ITS creation, the functioning and development of its integrated and instrumental subsystems, the meeting of the requirements for their effective deployment based on traffic simulation
The undertaken studies showed that the use of dynamic traffic re-routing (DTR) in the initial conditions of motion, determined, for example, by the level of service A, would be efficient only in 2% of the traffic situations determined by traffic flow threshold condition
Summary
The efficient use of the transport city infrastructure is mostly determined by the existence and operation of intelligent transport systems (ITS). The analysis of the current traffic conditions and congestion level of main highways reveals the topical character of scientific research in the field of efficient traffic flow management. That is why the dynamic traffic re-routing from road sections with heavy traffic to the alternative routes is so important. The development of monitoring traffic flow systems and methods of traffic assignment on the road network using simulation model allows us to analyze the problem of dynamic traffic re-routing on a new level. In Russian cities with a level of motorization 300 ÷ 500 veh per 1000 inhabitants, at least 20% of the sections of the main road network operate under an unacceptable v/c ratio that equal more than 0.7. The method of reducing the traffic congestion by means of dynamic traffic re-routing (DTR) to alternative routes becomes especially topical
