1、L摘要城市公共交通与人民的生产生活息息相关,优先发展公共交通是缓解城市拥堵、提高资源利用率的重要手段,目前已作为一种战略思想被广泛认同并实施。城市公交线网布局是影响城市公共交通系统运行的主要因素之一,对公交线网进行合理布设与优化可以方便乘客出行、减少公交运营成本,从而提高公交系统的运行效率。本论文对怀化市公交线网进行了优化研究,首先分析了怀化市的城市布局和交通状况,对公交客流进行了调查与预测,之后阐述了公交线网优化的基本原则和优化目标,在此基础上,确定了公交线网优化模型及约束条件,依据功能层次分析,提出了“分层调整,线路调整措施为主,站点、调度调整措施为辅”的优化调整思路,最后结合
2、怀化市公交路网、客流状况等现状因素对怀化市现状公交线网进行了调整和新增,通过对优化后的路网进行评价,证实了优化方案的可行性。本论文通过对怀化市公交线网进行优化研究,可以为怀化市相关部门提供决策参考,也为中等城市的公交线网优化提供了理论支撑与实践参考,对优先发展公共交通,落实节能减排、实现资源节约型和环境友好型社会具有重要意义。关键词:城市公共交通;线网优化;层次分析;优化模型;怀化市LABSTRACTUrbanPublicTransportationiscloselyrelatedtopeople’Sproductionandlife,givingprioritytourbanpu
