轨道开通后跨海通道公交方式结构变化研究——以厦门市为例

The Structural Change of Cross-Sea Transit Mode After New Metro Opening:Taken Xiamen City as an Instance

轨道交通对促进城市新老城区或组团间联系起到重要作用,然而现有研究对于轨道新线开通后公交方式结构变化影响的研究较少。本文以厦门市为例,基于出行链,利用地铁、BRT和常规公交数据,进行三网融合下的OD推断,统计了跨海通道公共交通在交通系统中的结构、各公交方式在公交系统中的结构,公交客流量时变特征以及跨岛换乘来源去向的空间分布。研究结果显示,轨道交通在跨岛出行中占比约15%;跨岛公交出行具有潮汐特征,早高峰时段从岛外进入岛内的高峰小时系数为19.65%;部分换乘站跨岛换乘率超过30%,常规公交换乘呈现出明显的接驳特性。本案例的方法与结论也可应用于其他城市新开通轨道的客流结构变化评估。

Metro plays an important role in enhancing contact between different districts or old-new town.However,there is less research on the impact of changes in the structure of public transportation mode after the opening of the new metro.Taken Xiamen City as an instance,OD was inferred based on the trip chain after fusion of metro,BRT and bus network.In cross-sea travels,the structural changes of public transit in all transportation system,the structural changes of each mode of public transit in public transit system and spatio-temporal cross-sea travel distribution were analyzed.The results show that metro travels account for about 15%of all cross-sea travel.Tidal characteristics can be found in cross-sea travels by taking public transit and 19.65%cross-sea travels happen in the morning peak hour.Cross-sea transfer rate even more than 30%and bus transfers show obvious feeder characteristics.The methods and conclusions in this paper can also be applied to the evaluation of transit passenger structural change after the new metro opening in other cities.
