The invention relates to the technical field of intelligent traffic control, in particular to a vehicle common driving route acquiring method and a vehicle common driving route acquiring device. The vehicle common driving route acquiring method comprises the steps of: acquiring time intervals of vehicles passing through a detection point position in a database vehicle passing table through vehicleinformation, and then acquiring a time interval average value through adopting a method of averaging; calculating to obtain a time interval standard deviation through adopting a Bessel formula basedon the time interval and the time interval average value; when a difference value between the (m+1) th time interval of the vehicle and the average value of the m-th time interval is greater than three times of the m-th time interval standard deviation, determining that a m-th detection point position is a single-time travel destination of the vehicle, and acquiring a single-time vehicle travel path through recognition; and identifying in a database to obtain a single-time vehicle travel path set based on the same starting point and destination, and screening the single-time vehicle travel path with the highest content repetition frequency, so as to determine the single-time vehicle travel path as a common vehicle travel path of the vehicle.
本申请涉及智能交通控制技术领域,特别地,涉及车辆常用行驶路线获取方法及装置。本申请提供了一种车辆常用行驶路线获取方法,包括:通过车辆信息在数据库过车表中获取车辆通过检测点位的时间间隔,然后通过求平均值的方法得到时间间隔平均值;基于时间间隔和时间间隔平均值通过贝塞尔公式计算得到时间间隔标准差;当所述车辆的第m+1个时间间隔与第m个时间间隔平均值的差值大于3倍的第m个时间间隔标准差时,判定第m个检测点位为车辆单次出行目的地并识别得到单次车辆出行路径;基于相同的起点和目的地,在数据库中识别得到单次车辆出行路径集合,筛选内容重复次数最多的单次车辆出行路径判定为所述车辆的车辆常用行驶路线。
