The invention discloses a method for evaluating the prediction precision of travel time required between any two points of an expressway. The method comprises the following steps: acquiring the current position, speed and destination position of each vehicle running in a to-be-predicted range on the expressway and a first moment corresponding to the current position; predicting first travel time required by the target vehicle to reach the destination position from the current position according to the current position, the speed and the destination position of each vehicle; obtaining a secondmoment when the target vehicle arrives at the destination position from the current position; according to the first moment and the second moment, calculating second travel time actually required by the target vehicle from the current position to the destination position; and according to the first travel time and the second travel time, calculating the prediction precision of the travel time required for the target vehicle to arrive at the destination position from the current position. According to the embodiment of the invention, the predicted first travel time is compared with the actual second travel time, so that the precision of the predicted first travel time can be calculated, and the method is simple and practical.
本发明公开了一种评价快速路任意两点间所需旅行时间预测精度的方法,包括:获取快速路上待预测范围内行驶的各车辆的当前位置、速度、目的地位置及当前位置对应的第一时刻;根据各车辆的当前位置、速度及目的地位置预测目标车辆从当前位置到达目的地位置之间所需的第一旅行时间;获取目标车辆从当前位置到达目的地位置的第二时刻;根据第一时刻和第二时刻计算目标车辆从当前位置到达目的地位置之间实际所需的第二旅行时间;根据第一旅行时间、第二旅行时间计算目标车辆从当前位置到达目的地位置所需旅行时间的预测精度。本发明实施例将预测的第一旅行时间与实际的第二旅行时间进行比较,从而可以算出预测的第一旅行时间的精度,方法简单实用。
