摘要
在分析轨道交通对常规公交客流的诱增、分流和互补等三种作用效应的基础上,采用定性与定量组合优化方法从公交整体线网结构调整和公交接运线路优化两方面进行常规公交线网的优化分析。在整体线网结构调整中,依据线网的功能层次、功能结构、整体规模与公交线路长度等特性,分别进行取消、缩短、调整线路走向等优化;接运线路优化则以接运效率为优化目标、构建目标优化模型进行优化。以Z市为例,对轨道作用效应下的Z市常规公交线网进行优化,优化后,取消线路1条,缩短线路1条,保持现状4条,调整16条线路走向,新设接运线路9条,公交性能指标大幅提升,优化结果表明组合优化方法能较好地实现公交线网优化目标。
Based on the analysis of the affection such as growth, sharing and complementary, we analysed the qualitative and quantitative combinatorial optimization of public transport network on integrated network adjustment and feeder bus routes optimization. According to the function level of the network, the functional structure, the network scale and the length of bus routes, we optimized the bus network, such as canceling, shortening, changing and so on. We also carried out the feeder bus routes optimization by setting feeder efficiency as the optimization goal and building an optimization model for the goal. Taking City Z for example, we made an optimization of conventional bus network under rail transit interaction effect by canceling 1 line, shortening 1 line, adjusting the routes of 16 lines, maintaining 4 lines and planning 9 new feeder lines. After the optimization, the performance indexes increased substantially. The result shows that the combinatorial optimization method can achieve the bus network optimization objectives.
