多层次公交线网规划实用方法

A Planning Method for Multi-hierarchy Public Transit Route Network

为满足我国大城市居民公交出行需求的多样性,解决公交系统服务水平低下、公交线网结构不合理等问题,提出'分区服务、逐层展开、整体优化'的规划思想,建立多层次公交线网规划的实用方法.该方法假设轨道线网确定,进行各级公交枢纽布局优化,快线以路线效率最大为目标,普线以直达客流密度最大为目标,支线以线网覆盖率最大为目标,各层次公交线网约束条件取值不同,布局优化方法不同,并列出了详细布设流程.

In order to meet a variety of demands of resident trip and improve the level of service of PT（public transit） system and solve the problem of network structure,this paper presents a planning method for multi-hierarchy public transit route network that is based on the idea of serving for district,plan layer by layer,optimizing for PT network.On the assumption that railway routing planning is completed,layout planning for multimodal terminals is implemented,the optimization object of rapid transit route is to maximize network efficiency,and the optimization object of bus route is to maximize nonstop bus passenger density,and the optimization object of branch bus route is to maximize the numbers of stops covered by bus route.Every hierarchy network＇s constraint condition and location optimization method is different,and its planning flow is built.
