山地旅游轨道交通单双线组合模式设计与评价

Design and Evaluation of Single-Double Line Combination Mode for Mountain Tourism Rail Transit

为适应山地旅游轨道交通客流空间分布不均衡的特征,本文提出一种新的轨道交通运营模式——单双线组合运营。在详细分析山地旅游轨道交通客流空间特征、单双线确定原则的基础上,提出三种组合运营模式:单线+双线、单线+双线+单线、双线+单线+双线,并采用AHP-模糊综合评价法从客流运输需求、交通运输条件、工程建设、运营经济四个方面评价运营模式的可行性。以遂昌山地旅游轨道交通为例进行单双线组合模式的应用,算例表明:山地旅游轨道交通单双线组合运营模式下交通运输条件和运营经济均满足要求,线路的通过能力和客流需求有较好的适配性,相比全线双线工程建设投资可减少10.8%。

To accommodate the characteristics of uneven spatial distribution of mountain tourist rail transit passenger flow,this paper proposes a new rail transportation operation mode:single-double line combined operation.On the basis of a detailed analysis of the spatial characteristics of passenger flows in mountain tourism railways and the principles of determining single and double lines,three combined operation modes are proposed:single line+double line,single line+double line+single line,and double line+single line+double line.The AHP-fuzzy comprehensive evaluation method are used to evaluate the feasibility of single-double line combined operation from four aspects:passenger transport demand,transport conditions,engineering construction and operation economy.The application of the single-double line combination mode with Suichang mountain tourism rail transit as an example shows that the transportation conditions and operation economy of the single-double line combination operation mode of mountain tourism rail transit meet the requirements,and the line has good adaptability in terms of passing capacity and passenger flow demand,and the construction investment can be reduced by 10.8%compared with the full double line.
