Abstract

The invention discloses a special vehicle signal priority control method based on a global position system (GPS). The special vehicle signal priority control method is a data processing method which bases on signal prior route configuration information and real-time GPS data, utilizes the geographic information system (GIS) technology, automatically identifies signalized intersections which need executing a signal priority control scheme through an electric fence, automatically identifies signalized intersections which need recovering a normal signal control scheme through road segment map matching and an unlocking delayer, and takes multiple signal prior tasks into consider at the same time. The special vehicle signal priority control method can flexibly provide an autonomous and intelligentized signal prior service for various special vehicles, and has a positive meaning in improving the signal prior service level for the special vehicles and achieving informatization and intelligence of urban traffic management.

Description

technical field [0001] The invention relates to the field of intelligent traffic signal control, in particular to a special vehicle traffic signal priority control method based on GPS positioning data. Background technique [0002] Special vehicles, such as fire trucks, ambulances, emergency vehicles, police cars, etc., perform special missions that are directly related to the safety of people's lives and property. Therefore, it has always been one of the important responsibilities of urban traffic managers to ensure their right to drive on roads. . [0003] The execution of traditional signal priority tasks requires dispatching a large number of police forces to signalized intersections where priority vehicles pass in advance. Through the collaboration between traffic police on duty, artificially adjust the working status of signal machines to open up signal priority paths for special vehicles. With the popularization of the distributed urban traffic signal control system,...
