The invention relates to the field of intelligent transportation, discloses a new emergency vehicle preferential pass method and system based on vehicle-road cooperation, and particularly provides a new emergency vehicle preferential pass method for signal timing and vehicle speed guidance of an intersection. The new emergency vehicle preferential pass system comprises a road side unit and a vehicle-mounted unit. By means of a vehicle-road cooperation method, due to real-time information interaction between an emergency vehicle and a road side signal control system, when the emergency vehicle gets into an intersection communication range, the road side signal control system can generate a corresponding emergency vehicle preferential pass scheme according to the current signal phase and the actual situation of vehicles queuing up at the intersection. Under the premise that vehicle confliction is avoided, signal timing and vehicle speed guidance are carried out, and therefore the emergency vehicle passes preferentially. Meanwhile, by means of the new method, adverse effects of preferential pass of the emergency vehicle on conventional social traffic flow can be reduced.
