配合城市轨道交通的接运公交车区域布设

With the layout of regional city rail transit feeder bus

为了充分发挥轨道交通在城市交通中的骨干作用以及接运公交的集散作用,提出了配合城市轨道交通的接运公交车区域布设模型。分析城市轨道交通与接运公交之间的关系,提出边际出行距离的概念,即选择常规公交直达以及选择常规公交—轨道交通换乘所消耗的广义成本,其中特别考虑了服务水平对乘客选择的影响。并对居民收入水平、轨道交通的票价设置以及乘常规公交距离与出行总距离的比值大小对于边际出行距离的影响进行了敏感性分析。进而考虑各站点的OD分布,建立以全部乘客总出行时间最小值为目标,以边际出行距离为约束条件的区域布设模型并设计算法求解。最后通过对北京市5号线城市轨道交通与常规公共汽车之间衔接的数值实例进行分析,显示了该模型符合实际情况,易于应用。

In order to give full play to the backbone role of rail transit in urban transportation and the role of collection and distribution of pick-up buses,a regional layout model of pick-up buses matching with urban rail transit is proposed.This paper analyzes the relationship between urban rail transit and pick-up bus,and puts forward the concept of margin al travel distance,that is,the generalized cost of choosing direct bus and transfer between normal bus and rail transit,es pecially considering the impact of service level on passenger selection.In addition,sensitivity analysis is made on the in fluence of residents'income level,ticket price setting of rail transit and the ratio of the distance between conventional public transport and the total travel distance on the marginal travel distance.Then,considering the OD distribution of each station,a regional layout model with the minimum total travel time of all passengers as the goal and the marginal travel distance as the constraint condition is established and the algorithm is designed to solve it.Finally,through the analysis of the numerical example of the connection between the urban rail transit and the conventional bus of Beijing line 5,it shows that the model is in line with the actual situation and easy to apply.
