【摘要】：为了适应我国社会主义现代化建设的需要,满足日益增长的客货运需求以及提高铁路与公路、航空运输在运输市场上的竞争力,通过分析和总结各发达国家铁路建设的经验,结合我国的国情、路情以及国民经济发展现状,《中长期铁路网规划》提出实施客货分线运输,修建高速客运专线是解决以上问题最有效的办法。速度目标值不仅是高速客运专线行车技术的核心指标,而且是客运专线铁路建设项目的设计依据,速度目标值越高,项目建设投资越大,运输成本越高,相应票价率水平也要越高,影响旅客的对该运输方式的出行选择行为；同时,速度目标值的提高将缩短旅行时间,对旅客出行又具有很强的吸引力。因此,速度目标值的选择要具有一定的科学前瞻性,既要在技术上着眼于长远发展,又要保证经济上合理,更要使客运专线在我国综合交通运输体系中发挥骨干作用的优势,提高客运专线的市场竞争力。本文通过对影响速度目标值方案确定的土建投资、列车性能、线路技术标准、运营成本、运营收益、行车组织、线路能力、完善路网结构以及对社会效益和经济效益带来的影响等因素进行综合分析,提出了基于层次权重分析法的客运专线速度目标值模糊综合决策模型。该模型通过对各影响因素之间的相互关系的分析建立系统化、层次化的评价指标体系,针对不同影响因素在客运专线速度目标值决策时的重要程度不同,运用层次权重分析法选取不同的权重系数。在构造模糊综合评判矩阵时,运用模糊系统理论对定性因素进行合理的数值化,并且对不同方案下的评价指标的相对隶属度进行标准化处理以消除各评价指标间的量纲效应,最终得出相对最佳的客运专线速度目标值方案。
[Abstract]:In order to meet the needs of our country ' s socialist modernization , meet the increasing demands of passenger and freight and improve the competitiveness of railways and highways and air transport in the transportation market , through analyzing and summarizing the experiences of the railway construction in the developed countries , combining with the country ' s national conditions , road conditions and the development of the national economy , the long - term railway network planning is put forward to carry out the passenger and cargo distribution transportation , and the construction of the high - speed passenger dedicated line is the most effective way to solve the above problems .

The speed target value is not only the core index of the high - speed passenger dedicated line driving technology , but also the design basis of the passenger dedicated line railway construction project , the higher the speed target value , the higher the project construction investment , the higher the transportation cost , the higher the corresponding fare rate level , and the travel choice behavior of the passenger to the transportation mode .
At the same time , the improvement of the speed target value will shorten the travel time , and has a strong attraction to the passenger travel . Therefore , the choice of the speed target value should have certain scientific and forward - looking , not only to focus on the long - term development , but also to ensure the economic rationality , and to make the passenger dedicated line play the key role in the comprehensive transportation system of our country and improve the market competitiveness of the passenger dedicated line .

This paper makes a comprehensive analysis on the factors such as civil investment , train performance , line technical standard , operating cost , operating income , driving organization , line capacity , perfect road network structure and the influence on social benefit and economic benefit .
