The invention provides a special traffic signal control system based on the matching correction of GPS and GIS lines. The system comprises a GPS module, a GIS rectification module, a decision module,a circuit configuration module and a wireless communication module arranged in a special vehicle, a monitoring module and a signal control command module arranged in a command center, wherein the GPSmodule is connected to the GIS rectification module which is connected to the decision module, the decision module calls the data of the circuit configuration module is connected to the signal controlcommand module by using the wireless communication module, the monitoring module can obtain running states and data of the GIS rectification module, the signal control command module and the circuitconfiguration module, and the signal control command module communicates with signal machines at intersections and is in mutual communication with the wireless communication module in the special vehicle. According to the system, the work can be simplified in performing special line tasks, the investment of police force is reduced, and the influence on social traffic is weakened.
Description
technical field [0001] The invention relates to the field of traffic special service signal control, in particular to a special service traffic signal control system for GPS and GIS line matching and deviation correction and a control method through the control system. Background technique [0002] With the continuous expansion of cities, there are more and more emergencies of various types, such as fire fighting, emergency rescue, police work, and ambulance. The above emergencies require special service vehicles to arrive at the scene as soon as possible, and the vehicles are often stuck by red lights at intersections during driving, so that special service vehicles cannot reach the incident site in time, which directly affects the lives and property safety of the people. Therefore, special service signal priority control is of great significance to social security. [0003] The existing special service traffic signal control needs to allocate police force to the intersect...
