基于全局运输成本的煤炭铁水联运通道走向分析

Directionanalysis of Railway-waterway Multimodal Transport Corridor Based on the Global Transportation Cost

铁水联运是我国未来交通设施发展的重要方向.当前,在铁路货运通道走向的规划中主要考虑工程造价,并结合对社会、环保因素的定性分析,忽略了通道建成后对区域全局运输成本的影响.针对上述问题,本文提出了一种基于区域全局运输成本分析的铁路货运通道走向规划方法,在考虑供应地与需求地的货种匹配程度基础上对运输规划模型进行改进,从而使得备选走向方案能兼顾区域全局运输成本最优.

The transport facilities of China predominantly tend to railway-waterway multimodal transport in the coming future. At present,the direction planning of the railway freight corridor has been decided by the factors of engineering cost,combined with the qualitative analysis of society and environment. It neglected that the regional optimal transportation cost will change after the corridor works. Aimed this problem,a direction planning of railway freight corridor based on the analysis of global transportation cost is provided in this paper,through the enhanced transport model in which the supply-demand matching coefficients was considered.
