The embodiment of the invention provides a special vehicle passing control method and system based on a V2X annunciator, and belongs to the technical field of passing control of special vehicles. The method comprises the steps: obtaining a current type of a special vehicle and task existence data showing whether the special vehicle has an emergency task or not; acquiring current emergency degree data reflecting the task emergency degree of the special vehicle; determining a current emergency degree threshold value corresponding to the current type according to a preset corresponding relationship between the type of the special vehicle and an emergency degree data threshold value; and determining a signal lamp control strategy of the intersection according to a comparison result among the current type of the special vehicle, the current emergency degree data and the current emergency degree threshold value, the obtained estimated time when the special vehicle arrives at the intersection and the target lane of the special vehicle. The vehicle traffic condition can be determined based on the actual condition and the actual vehicle type of the special vehicle, so that the healthy traffic state of the road is not influenced as far as possible.

    本发明实施例提供基于V2X信号机的特殊车辆通行控制方法、系统,属于特殊车辆的通行控制的技术领域。包括:获取特殊车辆的当前类型及示出该特殊车辆是否存在紧急任务的任务存在数据;获取反映特殊车辆的任务紧急程度的当前紧急程度数据;根据预设定的特殊车辆的类型与紧急程度数据阈值之间的对应关系,确定当前类型对应的当前紧急程度阈值;根据该特殊车辆的当前类型、当前紧急程度数据与当前紧急程度阈值之间的比较结果、获取到的该特殊车辆到达路口的预估时间以及该特殊车辆的目标车道,确定路口的信号灯控制策略。本发明可以基于特殊车辆的实际情况、实际车辆类型类确定车辆通行情况,以尽可能的不影响道路的健康通行状态。
