Vehicle flow-distributing connection traffic system of urban road crossroads and control method

Abstract

The invention discloses a vehicle flow-distributing connection traffic system of urban road crossroads and a control method. Reasonable vehicle traffic roads are arranged at the crossroads, and the spaces and speed limiting setting of all the crossroads are reasonably controlled so that mutual influence between lanes can be small, simultaneous rapid traffic of the multiple lanes in the north-southdirection and the east-west direction can be guaranteed, the vehicle traffic efficiency is improved, and the utilization rate of urban roads is increased.

Problems solved by technology

[0002] At present, the number of motor vehicles in major cities continues to increase, and urban road traffic congestion is becoming more and more serious. Major cities are exploring various solutions to control traffic congestion, for example, restricting the issuance of motor vehicle license plates, restrictions on vehicles in different places, and restrictions on odd and even numbers. , tidal lanes, building viaducts, underground tunnels and other programs, but they have not had good practical effects and have not completely solved urban road traffic congestion.

[0003] Existing urban road traffic facilities still have deficiencies, for example, the disadvantages of motor vehicles turning left at intersections of urban road traffic, the existing urban road traffic congestion is mainly caused by motor vehicles turning left at intersections, which takes up a lot of resources, and the traffic lights are set as straight-going machines. Motor vehicles and left-turning motor vehicles combine to pass with green lights at the same time, and the traffic lights in the other three directions are red lights, motor vehicles are restricted from waiting for two-way straight motor vehicles to pass through. After passing through, turn to two-way left-turn motor vehicles to turn left at the same time, and the two-way left-turn generally takes 30 seconds. This combination of traffic restricts the flow of urban road traffic motor vehicles, consumes urban road resources, and restricts urban road resources. utilization efficiency

[0004] Urban road traffic traffic jams at crossroads. Due to the long cycle time of traffic lights at crossroads, a large number of motor vehicles are backlogged on urban roads. Motor vehicles cannot pass quickly when the green light is on at crossroads, and a large number of motor vehicles stay in the intersection. , aggravated urban road traffic congestion

In addition, there are disadvantages of motor vehicles turning around. The traffic lights of motor vehicles are mostly for straight-going motor vehicles and left-turn motor vehicles. road resources
