The invention discloses a regional bus signal priority method based on bus demands. The method includes the following steps of (1) carrying out region-grade bus priority judgment, and comparing conflict priority requests of current intersections to obtain a bus route i with the toppest priority, (2) carrying out a route-grade bus priority judgment, judging whether the bus route i is in a late state or a normal state, executing a route-grade bus priority if the bus route i is in the late state, and otherwise, executing an intersection-grade bus priority, (3) as for the intersection-grade bus priority, judging whether a priority vehicle at a current intersection is in a late state or a normal state, executing a normal intersection priority mode when the vehicle is in the normal state, and executing the late intersection priority mode when the vehicle is in the late state. By means of the method, on one hand, the probability that multiple bus routes trigger a priority processing conflict problem at an intersection at the same time is avoided, on the other hand, the intersection-grade bus priority and an intelligent selection single-intersection priority mode can be achieved, and the priority effect is maintained during a traffic jam.
