中文摘要：

从线路技术指标及性质定位方面分析城市常规公交线路存在的主要问题,提出线路调整优化的11条原则。分析城市公交线路的技术指标和效益指标,选择调整优化线路。对调整优化线路从线路客流分担率、复线系数-客流量关系图、平均满载率调整值-复线系数关系图进行综合分析,选择待调整优化站点。考虑现状场站布局、线路布设、线网密度、客流分布对待调整线路进行调整优化,对于具有多重性质的线路可对其进行适当拆分并合理调整。实例应用表明,该方法操作方便,提高了调整线路及整个线网的运行质量。

英文摘要：

This article analyzes the main problems in the urban conventional bus routes from the line technical indicators and the nature orientation,and puts forward 11 principles of the optimization of the line adjustment.The technical indicators and efficiency indicators are analyzed,on which the adjustment and optimization of the line are selected. A comprehensive analysis is made based on passenger-flow percentages,double line coefficient and the distribution rate of passenger flows diagram and the average load ratio adjustment value-line coefficient diagram to adjust and optimize the lines. The adjustment and optimization are performed considering the status of station layout,lines layout and density,flow distribution,and for multiple lines with multi-functions can be appropriately adjusted. The practical project shows that this method is easy to operate and improves the quality of inter-city transportation.
