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.
