为解决公路货物周转量结构性数据缺失的问题,将公路货物周转量分为车辆货物周转量和路网货物周转量。依托车辆年检平台,进行抽样调查获得车辆货物周转量,根据车辆行驶里程比例将车辆货物周转量分配到不同路网。以高速公路收费系统和普通公路交通量观测站为平台,获取交通量数据。结合24 h现场抽样调查数据,推算区域路网货物周转量,并按车籍比例进行分割。将车辆和路网货物周转量的细分结果对接分析,得到总的货物周转量的结构和分布,并以江苏省推广结果作为分析实例。分析结果表明:从车辆货物周转量角度计算,江苏货车的本地和外地比例分别为65.39%和34.61%;从路网货物周转量角度计算,高速公路占43.00%,普通收费公路占31.61%,其他公路占25.39%;从车籍角度计算,江苏货车占40.80%,外省货车占59.20%,外省货车在高速公路上的货物周转量是江苏货车的4倍。
In order to solve the problem of missing structural data of highway freight turnover, the highway freight turnover is divided into vehicle freight turnover and road freight turnover. Relying on the annual inspection platform for vehicles, the sample survey was conducted to obtain the vehicle cargo turnover, and the vehicle cargo turnover was allocated to different road networks based on the proportion of vehicle mileage. Take the toll collection system of the highway and ordinary traffic observatory as a platform to obtain traffic data. Combined with 24 h site sampling survey data, calculate the road network goods turnover, and according to the proportion of car ownership split. The vehicle and road network traffic volume breakdown of the docking analysis results, the total turnover of goods structure and distribution, and to promote the results of Jiangsu Province as an example. The results show that: from the perspective of vehicle cargo turnover, the local and foreign ratio of Jiangsu trucks are 65.39% and 34.61% respectively. From the perspective of road network cargo turnover, expressway accounts for 43.00%, ordinary toll road accounts for 31.61% and other Highway accounted for 25.39%; from the perspective of car records, Jiangsu trucks accounted for 40.80%, other provinces accounted for 59.20% of trucks, trucks on the highway in the province of goods turnover is 4 times the truck in Jiangsu.
