The invention provides a road function change determination method and device, and the method comprises the steps: obtaining the vehicle track data of a vehicle passing a target road in a preset timeperiod, and the road function information of the target road starting from the preset time period; determining queuing length change information of the target road in the preset time period accordingto the vehicle trajectory data; and generating road function change information of the target road in the preset time period according to the queuing length change information and the road function information starting from the preset time period. Based on vehicle trajectory data and road function information starting from a preset time period, the road function change information of the road in the preset time period is automatically generated; and compared with a current road function change information obtaining mode, information obtaining is more timely, efficiency is higher, the road function change information can be notified to the travel user in time, and convenience is provided for the travel user.

    本申请提供了一种道路功能变化确定方法以及装置,其中,该方法包括:获取在预设时间段内驶过目标道路的车辆的车辆轨迹数据,以及所述目标道路在所述预设时间段开始的道路功能信息;根据所述车辆轨迹数据,确定所述目标道路在所述预设时间段内的排队长度变化信息;根据所述排队长度变化信息,以及在所述预设时间段开始的道路功能信息,生成所述目标道路在所述预设时间段内的道路功能变化信息。本申请实施例基于车辆轨迹数据和预设时间段开始的道路功能信息,自动生成道路在预设时间段的道路功能变化信息,相比当前的道路功能变化信息获取方式,信息获取更及时、效率更高,并且可以实现将道路功能变化信息及时通知给出行用户,为出行用户提供便利。
