摘要
针对应急车辆的路段行程时间计算问题,选择了具有代表性的单向2车道道路,在假设应急车辆不更换车道的条件下,根据应急车辆行驶规则,构建了城市道路应急车辆的2车道路段行程时间计算模型。得出行程时间和路段长度,自由流车速,常规车辆的平均车速,更换车道时间,车流的车头时距的关系。验证结果显示,该模型具有一定的适用性。
The travel time plays a crucial role in reducing the loss of assets and lives caused by emergencies. According to the driving rule of emergency vehicle, a travel time model of one-way two-lane highway was established. The relation between travel time and the distance, free speed, average speed, and headway time was obtained. The model was verified. The result shows that it is feasible.
