The invention discloses a priority control method and a priority control system for passing of a tramcar at an intersection. The system mainly comprises an intersection priority control cabinet and a road traffic signal control machine. When the intersection priority control cabinet receives a priority request of a first tramcar, a route of the first tramcar is arranged and locked. When tramcars of the other lines need to pass the intersection at the same time, a driver can send a priority request with an unlocking command to ground control equipment if the phase requested by a second tramcar is located at a green light state. The intersection priority control cabinet receives the priority request with the unlocking command of the second tramcar and judges whether an unlocking condition is satisfied or not, the current route is unlocked if the unlocking condition is satisfied, a route of the second tramcar is arranged, the priority request of the second tramcar is processed at the same time, otherwise, the priority request of the first tramcar is processed. The scheme disclosed by the invention can carry out effective priority control on a circumstance that one or more tramcars pass the intersection, thereby ensuring the running efficiency of the tramcars.
