Problems solved by technology
[0006] 1) It is necessary to increase equipment and bring about a substantial upgrade of existing intersection traffic signal equipment, and the cost is relatively high
[0007] 2) When the on-board priority request device fails to detect equipment, the priority control will fail, which may lead to the situation of waiting for the crossing all the time

Embodiment Construction
[0026] Such as figure 1 Shown, be the equipment that the special signal light control method of streetcar crossing of the present invention uses, comprise: vehicle-mounted GPS positioning device 1, central data server 4, special signal light control system, speed indicator board 2 and be arranged on the trigger of the car direction of crossing Area 7, the vehicle-mounted GPS positioning device 1 is installed on the tram, the special signal light control system includes a special signal light 3 arranged at the intersection and a special signal light control server 5 for controlling the special signal light 3, and the speed signs 2 are arranged at the intersection at intervals On the side close to the direction of oncoming traffic, the speed at which the driver is advised to travel is given. The speed of the speed sign is generally set to 35km / h or 40km / h, or a speed value between the two; the trigger area 7 is 100m away from the intersection, and the length of the trigger area ...

The invention provides a crossing special signal lamp control method for a tramcar. The method comprises the steps that a GPS positioning device is used for receiving a GPS signal, giving an absolute GPS position for a vehicle, and wirelessly transmitting the position to a central data server; and the central data server calculates the duration of each special traffic light according to a preference strategy, and transmits the data to a special signal lamp control system. When a vehicle is driven at the front of a crossing according to the corresponding specified speed, by means of synchronous coordination of signal lamp control and the driving speed, the crossing special signal lamp control method for a tramcar can guarantee that the vehicle can pass the crossing preferentially when the green light is on at the set preferential crossing.
Description
technical field [0001] The invention relates to a control method for priority release of trams passing through crossings, in particular to realize low-cost priority strategy control by adopting GPS positioning, wireless transmission and speed indication flags. Background technique [0002] Modern trams belong to ground rapid transit and run on the road together with social vehicles. There is inevitably a level intersection between its system and other lanes, and the tram will be affected and interfered by social signal lights when passing the intersection. From the perspective of bus priority in urban construction, technical measures are generally taken to ensure that the priority of trams is higher than that of social vehicles. [0003] There are generally two kinds of existing technical measures: one is that the tram car actively requests to control the intersection; [0004] The first one is the tram vehicle active control intersection scheme. It sends an active priori...
