摘要:
为优化货运交通结构并合理配置货运交通资源,研究了综合运输体系下基于运距的货运方式分担率.通过对国内城市间不同货运量与运距的集计数据进行统计分析,确定货运量与运距的函数关系式.随后,构建货运方式分担率-运距模型,并获取货运方式分担率-运距曲线.研究结果表明,各货运方式分担率随运距变化呈现出特定的分布规律.公路货运分担率-运距曲线呈单调递减趋势,在50~500 km运距范围内的分担率超过40%;铁路货运分担率-运距曲线呈先增后减趋势,拐点出现在600~700 km之间;水路货运分担率-运距曲线呈单调递增趋势;航空货运分担率-运距曲线在150~700 km运距范围内呈缓慢递增趋势,700~1 900 km运距范围内快速递增,运距超过1 900 km后趋于平缓.
Abstract:
In order to optimize the structure of the freight mode and reasonably allocate transportation resource, the mode split rate of freight transportation based on the transport distance in the comprehensive transportation system is studied. By statistically analyzing the aggregate data of different inter-city freight volumes and transport distances in China, the functional relationship between the freight volume and the transport distance is determined. Then, the mode split rate of the freight transportation-transport distance(MSRFT-TD)model is constructed, and the corresponding MSRFT-TD curve is obtained. The results show that there is specific distribution of the mode split rate of freight transportation with the change of the transport distance. The highway MSRFT-TD curve decreases monotonically and stays over 40% when the transport distance ranges from 50 to 500 km. The railway MSRFT-TD curve first increases and then decreases with a inflection point between 600 and 700 km. The waterway MSRFT-TD curve monotonically increases.
