Intelligent traffic guidance method based on floating car under congestion condition

Abstract

The invention relates to an intelligent traffic guidance method based on a floating car under a congestion condition. The method includes that by means of a city traffic information collecting and processing system based on the floating car, real-time average traveling speed Vi of a city road network and a real-time traffic condition are obtained, and a congested road section is identified; and based on a road network topological structure, the congested road section is divided into a guidance control area and a guidance buffering area according to the real-time average travelling speed Vi and the real-time traffic condition of the road network, and corresponding guidance information is generated automatically. On the basis of the city traffic information collecting and processing system, the real-time average traveling speed Vi of the city road network and the real-time traffic condition are obtained, traffic congestion is identified, a range of the guidance control area and the guidance buffering area is calculated, and the corresponding guidance information is generated. By means of the intelligent traffic guidance method, the congested road section can be identified automatically, a possible affecting area is determined intelligently, a traffic guidance problem under the congestion condition is fully solved, loss caused by the traffic congestion is effectively reduced, and operation efficiency of the road network is improved.

Description

technical field [0001] The invention relates to the field of intelligent traffic, in particular to an intelligent traffic guidance method based on a floating car in a congested state. Background technique [0002] At present, the phenomenon of urban traffic congestion is becoming more and more serious. Looking at the operating efficiency of the entire urban road network, it can be seen that traffic congestion is only a part of the road network, not all roads are congested at the same time. If the traffic flow of the congested roads is transferred to the road network For other road sections, the traffic flow in the urban traffic system is evenly distributed to the road network, so that the road load of the road network can be balanced, and the traffic congestion can be greatly improved to a certain extent, which requires traffic guidance. Traffic guidance is mainly that the manager guides the driving route of the driver through various measures, and through the guidance, the ...

Problems solved by technology

[0003] At present, the relatively successful research and development include the TravTek system in the United States, the Ali-scout system in Germany, and the navigation system in Japan. The research on traffic flow induction in my country is relatively late, and it mainly focuses on the research on induction hardware equipment and communication methods. There is a lack of systematic research on the scope and intensity of induction, and the impact of congested traffic flow on the surrounding roads of the road network is rarely considered
