摘　　要：重型货车行车记录仪的普及应用,为重型货车出行特征分析提供新的方法。以长春市全月货车GPS轨迹采集点为研究对象,建立数据清洗规则,对异常数据分类预处理。在OD识别过程中,提出了虚拟检查线方法,以识别过境车辆,同时结合了POI加油站类、控规用地性质分类和交通道路红线数据,用来标定停车点的阈值,并提出了路网匹配方法,对落位错误点纠偏。在上述工作基础上,得到了长春市货车行驶特性,包括时空特性、货运通道识别、速度和流量特性等,为城市货运交通规划决策提供依据,并提出相关建议。The widespread application of heavy-duty truck driving recorders provides new method for analyzing the travel characteristics of heavy-duty trucks.Taking the GPS trajectory collection points of monthly freight cars in Changchun City as the research object,we established data cleaning rules,classified and preprocessed abnormal data.In the OD recognition process,we proposed a virtual inspection line method to identify passing vehicles.At the same time,combining POI gas station classification,controlled land-use classification,and traffic road red line data,we calibrated the threshold of parking points,and proposed a road network matching method to correct positioning errors.On the basis of this,we obtained the driving characteristics of trucks in Changchun City,including spatio-temporal characteristics,identification of freight chan-nels,speed and flow characteristics,and proposed relevant suggestions,which could provide a basis for urban freight transportation planning and decision-making,.
