The invention discloses a method for solving intersection intermediary centrality based on vehicle trajectory data. The method comprises the steps of data preprocessing; matching and fitting the vehicle track data and the road space data; calculating road network intersection intermediary centrality by using the trajectory data; compared with data of a traditional traffic detector, the system hasa complete travel route, vehicle trajectory data of the system can better reflect the real travel demand and travel route of a road user, the result is more reasonable and accurate, and support is provided for road network operation quality evaluation, route optimization decision and network planning. From the perspective of data analysis, the intermediary centrality of a certain intersection canbe solved by cleaning and analyzing vehicle trajectory data; compared with other traffic data, the vehicle travel characteristics can be more truly reflected by solving through the graph theory model.
本发明公开了基于车辆轨迹数据求解交叉口中介中心性的方法,该方法的步骤包括数据预处理;车辆轨迹数据与道路空间数据匹配拟合;利用轨迹数据计算路网交叉口中介中心性;相较于传统交通检测器的数据,具有完整的出行线路,其车辆轨迹数据更能反映出道路使用者真实的出行需求与出行线路,结果更加合理准确,对于道路网运行质量评价,路径优化决策和网络规划提供支撑。从数据分析角度来讲,通过清洗、分析车辆轨迹数据,即可求解某交叉口的中介中心性;相较于其他交通数据,通过图论模型进行求解更能真实地反映车辆出行的特征。
