The invention provides a vehicle priority passing method and a signal machine. The method comprises the steps of: after a priority passing request of a vehicle is received, determining the priority passing direction of the vehicle at an intersection where the signal machine is located based on the priority passing request; comparing the current passing direction of the intersection with the priority passing direction, wherein the current passing direction is the direction in which vehicles are released at the intersection; and if the current passing direction is different from the priority passing direction, determining a first residual passing time length according to the passing time length of the current passing direction and a preset minimum passing time length, and when the first residual passing time length is reached, controlling each signal lamp of the intersection, and converting the current passing direction of the intersection into the priority passing direction, so that the vehicle passes through the intersection preferentially after arriving at the intersection. Therefore, the current passing direction is directly converted into the priority passing direction, and the efficiency of vehicle priority passing is improved.
Description
technical field [0001] The invention relates to the technical field of traffic signals, in particular to a vehicle priority passing method and a signal machine. Background technique [0002] Nowadays, the traffic pressure on urban roads is relatively high, and traffic jams are a prominent problem in urban traffic. However, special vehicles (such as customized public transport vehicles, ambulances and fire trucks, etc.) are often blocked at intersections in emergencies, thereby delaying time. [0003] In the prior art, most of the vehicle priority traffic methods realize relative priority traffic through the preset traffic sequence of each traffic direction. For example, if figure 1 As shown, vehicle A needs to have priority in the north-south direction, but the current direction of traffic is east-west. If the preset traffic order of each traffic direction at the intersection is: east-west direction (east→west, west→east), west-left direction, north-south direction (south...
