Embodiment Construction
[0041] The invention provides a green wave vehicle speed guidance method, such as figure 2 As shown, the method includes the following steps:
[0042] The backend server receives the vehicle data signals sent out by the vehicles traveling on the road within the set area according to the set frequency and the traffic light signals sent by the traffic lights at the first intersection and the second intersection within the set area; The data signal includes vehicle ID, vehicle position, current speed, and vehicle data signal sending time, and the traffic light signal includes traffic light position information, prohibition light duration, and traffic light duration information; the prohibition light is a traffic light indicating that vehicles are prohibited from passing The status of the traffic light is the status of the traffic light indicating that the vehicle is allowed to pass;
[0043] The background server sequentially selects different vehicles as the guided vehicles, a...

The present invention provides a green wave vehicle speed guidance method and system, the method comprising: the background server receives the vehicle data signal sent by the vehicle on the road and the traffic light signal sent by the traffic lights at the first intersection and the second intersection; The traffic lights indicate the state of prohibiting vehicles from passing, and the traffic lights indicate the state of allowing vehicles to pass; the background server selects the guided vehicle, and according to the vehicle data signals of the guided vehicle and the preceding vehicle, two vehicles in the same lane are set. The safety distance between vehicles and the traffic light signals at the first intersection and the second intersection are calculated to obtain the driving speed and sent to the guided vehicle, so that when the guided vehicle travels to the second intersection at the driving speed, the second The traffic lights at the intersection are open to traffic. The invention can save the passing time of vehicles passing through the intersection and improve the passing efficiency of vehicles passing through the intersection.
Description
technical field [0001] The invention relates to the technical field of traffic control, in particular to a green wave vehicle speed guidance method and system. Background technique [0002] With the development of the automobile industry, the number of motor vehicles in the city is getting higher and higher, the traffic delay in the urban center of the big city is increasing, the driving speed is generally low, and even traffic jams and traffic accidents are formed. Long-term traffic congestion not only affects the travel efficiency of drivers and passengers, but also increases the pollution to the environment. Therefore, how to improve the traffic efficiency in the city has become the focus of urban traffic participants. Green wave is a coordinated control method for urban arterial roads that is widely used, that is, drivers can pass through various intersections unimpeded by driving at a guide speed on a specific road section, and the signal lights can always be green for...
