大城市多模式公交线网级配关系研究

The Gradation of Urban Multi-model Transit Networks

针对国内多模式公交线网规划缺乏依据的状况,以大城市多模式公交线网为研究对象,首先分析了城市居民的公交出行距离特征,借助双参数韦布尔分布建立了城市居民公交出行距离分布模型;基于广义出行费用,建立了各模式公交线网优势出行距离模型;基于供需平衡思想,构建了大城市多模式公交线网级配模型.以哈尔滨公交线网为例,测算得到了哈尔滨市2020年各模式公交线网的合理规模与级配关系,结果表明,测算的结果与2020年的预期需求较一致,说明建立的级配模型是合理可行的.

Aiming at the situation that the lack of the basis of multi- mode public transportation network planning in China, the characteristics of the urban public transport travel distance is analyzed, and the model of urban public transit distance distribution is established with the double parameter Weibull distribution.Based on the generalized travel cost, the model of multi- model transit network dominance trip distance is established. On the basis of supply and demand balance, the grading model of multi-modal transit network is determined. Taking Harbin transit network as an example, the reasonable scale and gradation of multi-model transit network in Harbin in 2020 are calculated. The results show that the calculated results are consistent with the expected demand in 2020, which shows that the model is reasonable and feasible.
