Abstract

The invention provides a prior control system and a method for road signals. The prior control system for the road signals comprises a vehicular detection device, a roadside transmission device and a control device of an annunciator; and the vehicular detection device is used for collecting the running information of a vehicle and transmitting the collected running information to the roadside transmission device by a wireless communication mode, the roadside transmission device is used for transmitting the received running information to the control device of the annunciator by a wired transmission mode, and the control device of the annunciator is used for controlling the running of a traffic signal lamp at an intersection according to the received running information. The running information of the vehicle can be accurately obtained by the vehicular detection device. Moreover, when the vehicle arrives at the position of the intersection, the vehicular detection device can be in wireless communication with the roadside transmission device, the running information is accurately transmitted to the roadside transmission device, the received running information is also transmitted to the control device of the annunciator by the roadside transmission device, the phenomenon of missing detection of the running information is effectively avoided, and the reliability of the prior control system for the road signals is enhanced.

Description

technical field [0001] The invention relates to the technical field of traffic signal control, in particular to a road signal priority control system and method. Background technique [0002] At present, with the continuous development of automobile technology, automobiles are widely used in people's daily life, the traffic pressure is also increasing, and traffic jams have become a common phenomenon in daily life. In order to ensure that special vehicles such as buses, fire trucks, ambulances or police cars can pass first, road signal priority control systems are usually used to control the operation of signal lights at intersections to ensure that special vehicles pass preferentially. The road signal priority control system in the prior art usually adopts ground induction coil or radio frequency identification technology. For the road signal priority control system using the ground induction coil technology, in order to bury the ground induction coil, it is necessary to ...
