摘要: 以往关于常规公交导向的路网密度研究偏重抽象的理论分析,缺乏具体的实证研究。通过选取上海9个典型案例,对比分析发现 它们都具有通常意义下的高密度公交网络,然而参照线路重复系数后可以确定这主要是因为客流强度过高,公交网络规模过巨 引起的。研究结果表明干道路网密度对公交线网密度的影响比整体的路网密度更大。因此,讨论路网密度时必须考虑道路等级 问题,即唯有适合公交运营的较高等级道路才对提高公交线网密度具有现实意义。

Abstract: In the past, the research about bus-led urban road network density emphasized on the theoretical analysis, and was lack of empirical research. 9 typical cases in Shanghai are selected in this paper. Through comparative analysis, we find that they all have high bus network density in the usual sense. But with refer to line repeat coefficient, we can find the reason that is high traffic intensity and giant bus network scale. The results show that the density of main road is more important than the density of the whole network. Therefore, it is necessary to consider the road grade when discussing road network density, that is, only the high grade road which is suitable for the public traffic operation can be of practical significance to improve the density of the bus line.
