城镇公交线网布局优化方法研究

针对目前我国城镇公交线网布局不合理,层次结构不明显,线网重复率高,线网密度和覆盖率低等问题,基于客观性、可行性、实用性的原则,给出了城镇公交线网优化的思路、步骤及方法,从公交线路的优良度排序、区域分布特征、与轨道和枢纽的接驳、居民的反馈意见及公交运输部门的利益均衡等方面进行了合理性分析,并对优化方案进行了评价。最后,进行了实例验证。应用结果表明该方法可操作性强,能够很好的兼顾各方面的利益,是切实可行的。

Research on Network Distribution Optimization of Town Public Transit

The town bus line network of our country at present is unreasonable;the hierarchical structure is not obvious;the repetitive rate of network is high,and the bus routes and coverage rate are low.For these questions,based on the principles of objectivity,feasibility and practicability,the optimization thinking,steps and methods of town and country public transit were elaborated and rationally analyzed,mainly from the aspects of fine degree order of the public transportation route,area distribute characteristics,pluging into track and pivot,feedback opinion of resident and public transit interests of transportation sector getting balanced respects.Finally the optimal program were evaluated.An example of Bao'an public transit planning was presented to prove this framework.Applied results show that this method can give a very good proper attention to various aspects benefit,and is feasible.
