Expressway vehicle OD point determination method based on checkpoint data

The embodiment of the invention discloses a rapid vehicle OD point determination method based on checkpoint data. According to the rapid vehicle OD point determination method based on the checkpoint data provided by the embodiment of the invention, OD extraction of a single travel track of a vehicle is carried out by defining a vehicle travel chain and combining the preprocessed original data; andthen, the integrity and classification of the single travel trajectory of the vehicle are analyzed, classification is carried out, and different OD point determination methods are adopted for the single travel trajectories of different types of vehicles, so that the method has the pertinence of urban expressways, and the OD point determination process is relatively simple. 本发明实施例公开了一种基于卡口数据的快速车辆OD点确定方法。本发明实施例提供的基于卡口数据的快速车辆OD点确定方法通过定义车辆出行链并结合预处理的原始数据进行车辆单次出行轨迹的OD提取，再分析车辆单次出行轨迹的完整性并分类，并针对不同类别的车辆单次出行轨迹采用不同的OD点确定方法，具有城市快速路的针对性且OD点确定过程相对简单。
