The invention discloses an urban road network main traffic flow path mining method based on AVI data, aims to mine continuous vehicle paths through the AVI data, overcomes the defect that existing section detection individual data is discontinuous, and provides an urban road network main traffic flow positioning method which is large in range, real-time and low in cost. The method mainly comprises the following steps: firstly, extracting vehicle, intersection, entrance lane, vehicle position and time information in AVI data, and then extracting information of every two intersections and entrance lanes through which each vehicle continuously passes as a sub-traffic flow path; and finally, collecting all sub-traffic flow paths, and splicing descending sub-traffic flow paths screened by a traffic threshold value to form a road network main traffic flow path.

    本发明公开了一种基于AVI数据的城市路网主车流路径挖掘方法,旨在通过AVI数据挖掘连续的车辆路径,克服现有断面检测个体数据不连续的弊端,提供一种大范围、实时及低成本的城市路网主车流定位方法。主要步骤包括:首先,提取AVI数据中车辆、交叉口、进口道、车辆位置和时间信息,然后提取每一辆车连续经过的每两个交叉口和进口道的信息,作为子车流路径;最后集计所有子车流路径,通过流量阈值筛选的降序子车流路径拼接形成路网主车流路径。
