在地公路货物运输量统计方法

提出了在地公路货物运输量的概念, 将非营运货车和外地货车纳入了在地货物运输量的统计范畴, 归纳了基础数据集; 通过分析车辆注册地、使用性质、路网等级和车流流向等因素, 提出了在地货物运输量的统计思路和拆分逻辑, 建立了在地公路货运量和货物周转量统计模型; 基于本市籍营运货车产生的货运量, 提出了在地货运量规模指数用以评估在地货运量的相对偏移程度和外地货车的参与程度。研究结果表明: 控制极限误差在10%以下时, 5种基础数据集, 即货运专项调查数据、高速公路联网收费数据、普通公路抽样调查数据、普通公路交通量调查数据和车辆管理所在册货车数据可完成在地货物运输量的精细化推算; 提出的统计模型使所研究城市创造每万元GDP的货物周转量与全国平均水平的相对偏差率为0.45%, 具有一致性; 所研究城市的在地货运量规模指数为2.47, 说明实体经济发达的城市中外地货车在当地参与运输的程度偏高; 本市籍营运货车货物运输量不足以支撑当地经济规划; 本市籍在册营运货车少并不能代表本市运力不足, 所研究城市的本市籍营运货车主要承担短途运输, 在总市内货运量中占66.28%, 而外地货车主要承担市际与省际间的货物交流, 在总跨市货运量中占79.16%;货车按车型计费后, 每种货车车型的平均载货质量与按车流划分的重车比将是在地货物运输量统计的关键参数; 省际间3轴及以上货车车流量存在着不均衡性。 

Statistical approach for the region-oriented volume of freight transport on highway

The concept of region-oriented freight transportation volume was proposed. Non-commercial trucks and nonlocal trucks were included in the statistics category of the region-oriented freight transportation volume, and the basic data sets were summarized. The factors of the registration place, usage, level of the highway network, and traffic flow direction of the vehicles were analyzed. Statistical thoughts and splitting logic of the freight transportation volume, and statistical models of freight volume and freight turnover volume were developed. Based on the freight volume of registered local commercial trucks, a scale index of region-oriented freight volume was created and used to evaluate the relative offset degree and involvement of nonlocal trucks. Analysis results show that when the limit error is controlled within 10%, the region-oriented freight volume can be evaluated exactly by five basic data sets: special survey data on freight transport, expressway network toll collection data, sample survey data of highway, traffic volume survey data of highway, and truck data in the register of vehicle management. For the studied city, the proposed statistical model embodies a 0.45% relative deviation rate of the freight turnover to create GDP per ten thousand yuan with the national average level, which is consistent. The scale index of region-oriented freight volume is 2.47, which indicates that nonlocal trucks involved in local freight transportation to a high degree in cities with developed real economy. The freight transportation volume of commercial trucks registered at the local government office is not sufficient to support economic planning. However, a lack of registered trucks does not indicate an insufficient transportation capacity. The commercial trucks registered locally mainly undertake short-distance freight transportation, which accounts for 66.28% of the total in-city freight volume. Nonlocal trucks mainly undertake inter-city and inter-provincial goods, which accounts for 79.16% of the total volume. In the near future, when trucks are charged by vehicle type, the average load of each vehicle type and the rate of each loaded truck in total will be key parameters for the evaluation of the region-oriented freight transportation volume. In addition, inter-provincial disequilibrium existed in the traffic volume of trucks with 3 axles or more.
