基于轨道交通的重庆市地面公交线网布局优化研究

Network Layout Optimization of Routine Bus System Based on Rail Transit in Chongqing

合理的轨道交通与地面公交线网一体化布局模式,可以提高城市公共交通系统的整体运行效率和服务水平,是大城市公共交通发展的必然趋势。以2012年为目标年,在分析重庆市城市空间布局结构、道路网络及轨交线网特征的基础上,以构建轨道交通与地面交通线网一体化的网络模式,提升城市公共交通的系统效益为目标,从公交线网结构、功能层次、线网规模等方面进行了分析,提出了适应重庆市交通现状及发展要求的轨道交通与地面公交一体化的网络布局模式及方案。利用层次分析法(AHP法)和模糊综合评判法对公交线网进行了效果验证,综合评价指标B为5.384,表明公交线路网处于较好的运营状态。

Reasonable network layout mode between rail transit and routine bus system can improve the overall operating efficiency and service levels of the city＇s public transport system. It is the inevitable trend of major cities＇ development of public transport. The paper uses the scientific theories and methods researching the bus network structure, function level and the size of the line network to build integration network layout mode to adapt Chongqing traffic situation and development requirements of rail transit and ground transportation targeted year 2012, so as to improve the efficiency of the public transport system and achieve the network layout mode, based on analysis of Chongqing urban space layout structure, the characteristics of the road network and rail network features. The Analytic Hierarchy Process （AHP） and fuzzy comprehensive evaluation method was used to evaluate the network of bus lines. Obtaining the comprehensive evaluation index B was 5.384 showing that the bus line network was in good operating condition.
