The invention discloses a method and a device for predicting travel time required between any two points of an expressway and computer equipment. 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; judging whether other vehicles exist between the position of the target vehicleand the destination position or not according to the current position of each vehicle; if other vehicles exist, judging whether the speed of each vehicle between the target vehicle and the destination position is smaller than or equal to a first preset threshold value or not according to the speed of each vehicle; if the speed of each vehicle is greater than a first preset threshold value, calculating a first distance between two adjacent vehicles between the target vehicle and the destination position and a second distance between the vehicle closest to the destination position and the destination position according to the current position and the destination position of each vehicle; and calculating travel time required for the target vehicle to arrive at the destination position from the current position according to the first distance, the second distance and the speed of each vehicle.
本发明公开了一种预测快速路任意两点间所需旅行时间的方法、装置及计算机设备,该方法包括:获取快速路上待预测范围内行驶的各车辆的当前位置、速度及目的地位置;根据各车辆的当前位置判断目标车辆所处位置与目的地位置之间是否存在其他车辆;如果存在其他车辆,根据各车辆的速度判断目标车辆与目的地位置之间各车辆的速度是否小于或等于第一预设阈值;如果上述各车辆的速度大于第一预设阈值,根据各车辆的当前位置、目的地位置计算目标车辆与目的地位置之间相邻两台车辆之间的第一距离及距离目的地位置最近的车辆与目的地位置之间的第二距离;根据第一距离、第二距离及各车辆的速度计算目标车辆从当前位置到达目的地位置所需的旅行时间。
