城市常规公交线网近期优化方法的研究.pdf

西南交通大学硕士研究生学位论文第1页摘要公交网络设计在公交规划中起决定作用,直接影响后面的规划决策。因此,合理公交线网是公共交通优先发展的前提,是提高公交竞争力的手段和提高公交服务水平的基础。近期公交线网优化有别于现有公交线网优化和远期规划特殊性,其研究内容不仅涉及微观层面的单条线路调整,还应考虑宏观层面的网络结构优化。本文从公交线网优化基础研究、公交线网近期优化方法确定和现有公交线网调整方法研究三个方面对公交线网近期优化进行系统研究。公交线网优化基础是公交线网优化的依据,主要包括线网优化的数据依据和理论依据。数据依据主要为公交出行分担量和公交0D分布。将线网优化常用模式、常用方法和常用优化目标作为近期优化方法研究的理论依据。公交线网近期优化方法确定研究是非常重要的。首先确定近期公交线网优化研究的内容,明确优化年限,接着系统研究现有线网存在的问题和近期公交线网优化目标和影响因素。分析近期线网优化的特殊性和宏观规划与微观优化相配合优化流程,确定了近期公交线网优化实用方法。现有公交线网优化调整方法研究。结合成都市现有公交线网,利用模糊评价法对现有公交线路网进行评价,结合模糊分析,提出现有线网中普线和支线调整目标、原则和方法。将城市轨道视为已建快速公交线路,提出配合城市轨道交通的现有公交线网优化调整原则和方法,并结合成都地铁l号线进行相关研究。关键词:公交线网,近期优化,模糊评价,优化调整西南交通大学硕士研究生学位论文第lI页 Abstract work design plays thedecisive roleintransitplanning,and directly affectsthe decisive roleofplanning decision—making istheprecondition ofpriority for public transport,and itisthe basisfordeveloping thepublic transport system servicelevel short—rangeoptimization ofthepublictransport work hasits specificity thatisdifferent from thelong-range planning and theoptimization ofthe current publictransport work,and whose researchobjects areconcerned with both the individual buslineadjustment atthemicro level structure optimization atthe macro level.
