The invention discloses a road intersection traffic structure change identification method. The identification method comprises the following steps: establishing a traffic network model comprising road network data, road intersection data and vehicle trajectory data; wherein the road intersection data comprises an intersection ID, an intersection passing direction, whether vehicles in the intersection passing direction can pass or not and an ID of a road driving into the intersection, and the vehicle passing direction is subjected to digital coding; and in the traffic network model, setting a circular buffer area by taking the intersection of the intersection as a circle center, carrying out clustering analysis on the vehicle sub-tracks in the buffer area, and carrying out intersection traffic structure change identification according to the vehicle track condition in a clustering cluster. According to the invention, whether the intersection traffic structure is changed can be automatically identified, and the reliability, accuracy and efficiency of identification are effectively improved.

    本发明公开了一种道路交叉口通行结构变化识别方法。所述识别方法包括:建立包括路网数据、道路交叉口数据和车辆轨迹数据的交通网络模型;其中,道路交叉口数据包括交叉口ID、交叉口通行方向、交叉口通行方向上车辆是否可通行、及驶入交叉口的道路的ID,并对其中车辆通行方向进行数字编码;在交通网络模型中,以交叉口的交叉点为圆心,设置圆形缓冲区,对缓冲区内的车辆子轨迹进行聚类分析,根据聚类簇内的车辆轨迹情况,进行交叉口通行结构变化的识别。本发明可自动化识别交叉口通行结构是否发生变化,有效提高了识别的可靠性、准确性和识别效率。
