Example Embodiment

[0029] In order to make the technical means, creative features, objectives and effects of the present invention easy to understand, the present invention will be further explained below in conjunction with specific embodiments.

[0030] Reference Figure 1-4 As shown, a dynamic adaptive green wave method based on vehicle-road coordination includes the following steps:

[0031] Step 1: After the vehicle reaches the signal detection range of the intersection signal control machine, the vehicle-mounted terminal sends vehicle information to the intersection signal control machine in the direction of the vehicle travel. The intersection signal control machine is installed at each intersection location, and the vehicle information includes the vehicle speed , The direction of travel of the vehicle and the distance between the vehicle and the intersection of the direction of travel, the intersection signal control unit is equipped with an RSU, and the vehicle-mounted terminal is an OBU;

Abstract

The invention discloses a dynamic self-adaptive green wave method based on vehicle-road collaboration. After vehicles drive into a signal detection range of an intersection signal control machine, vehicle-mounted terminals transmit vehicle information to the intersection signal control machine in a vehicle advancing direction; a roadside communication device receives the vehicle information and screens the vehicle information; after screening, the roadside communication device calculates an average speed of all vehicles in a certain time period, calculates a phase difference of the vehicles passing through the road section, and transmits the phase difference to an intersection signal control machine located at a next intersection; and the intersection signal control machine at the next intersection adjusts a street lamp time interval of the intersection according to the phase difference. The dynamic self-adaptive green wave method based on vehicle-road collaboration has the advantagesthat: firstly, the direction of large flow is determined according to flow information obtained through vehicle-road collaboration, and therefore a green wave route is switched to; secondly, the average vehicle speed is calculated according to the vehicle speeds obtained through vehicle-road collaboration, and therefore the green wave phase difference is configured; and thirdly, all-weather coverage of dynamic self-adaptive green waves in a vehicle-road collaboration mode is achieved.

Description

technical field [0001] The invention relates to the field of traffic, in particular to a dynamic adaptive green wave method based on vehicle-road coordination. Background technique [0002] In recent years, with the rapid growth of urban population and motor vehicle ownership, urban traffic problems have further aggravated. Intelligent traffic signal control can scientifically allocate traffic rights, improve traffic order, improve traffic capacity and traffic efficiency at road intersections, and reduce traffic delays. and waste of resources, improve the carrying capacity of regional and urban road networks, and effectively alleviate traffic congestion. [0003] Green wave control is a common coordinated control method for multiple intersections. Through green wave control, the traffic flow can continuously obtain green light signals one after another during driving, and pass through all intersections along the way unimpeded, realizing "green light all the way" Passage gre...
