Structure analysis and calculation method of freight turnover for regional highway

In order to solve the problem of the structural data loss of highway freight turnover, highway freight turnover was divided into vehicle freight turnover and highway network freight turnover.Relying on vehicle annual inspection platform, sampling survey was carried out, and vehicle freight turnover was obtained.According to the proportion of vehicle travelling mileage, vehicle freight turnover was assigned to different highway networks.Based on expressway toll systems and general highway traffic observation stations, traffic data were obtained.Combined with field sampling investigation data in 24 h, regional highway network freight turnover was estimated, and highway network freight turnover was breakdown according to the proportion of vehicle registered place.Linking vehicle freight turnover to highway network freight turnover, the structure and distribution of total freight turnover were obtained, and the generalization result in Jiangsu Province was analyzed.Analysis result shows that from the point of vehicle freight turnover, the proportions of local and non-local trucks in Jiangsu Province are 65.39%, 34.61% respectively.From the point of highway network freight turnover, 43.00% of total freight turnover is completed by expressway network, 31.61% of total freight turnover is completed by general toll highway, and 25.39% of total freight turnover is completed by other highways.From the point of vehicle registered place, 40.80% of total freight turnover is completed by the vehicles registered in Jiangsu Province, and 59.20% of total freight turnover is completed by the vehicles registered in other provinces.From the point of expressway freight turnover, the freight turnover of the vehicles in other provinces is four times than that of the vehicles in Jiangsu Province.
