基于ITS的公共交通换乘等待时间最短调度问题研究

Study of dispatching at minimum waiting time of public transportation transfer under the condition of ITS

为使公共交通的换乘时间实现最佳衔接,先进的公共交通系统的高效率和优势得以体现,在对各国研究现状分析的基础上,研究了ITS实时提供公共交通信息的条件下,公共交通换乘等待时间最短调度问题。为了对公共交通换乘总等待时间最短目标下的公共汽车发车时刻表确定方法进行分析,应用运筹学理论,分别针对一个换乘点和多个换乘点的情况建立了线性规划模型,并用一个换乘点的算例验证了模型的可行性和有效性。结果表明:该方法能最大限度地减少乘客换乘总等待时间,尤其是对于发车间隔较大的公共交通方式间换乘的时间节约效果更为明显。

Based on past study,and intelligent transportation systems providing real-time information,authors study on dispatching at public transfer so as to minimize waiting time when transferring among different transit service,optimizing transit transfer time,and incarnating efficiency and advantage of APTS. In order to analyze the method of establishing bus schedules with the goal of enabling short waiting time when transferring among public lines,authors apply linear programming model and validate the feasibility of the model with application examples through a transfer terminal. The result indicates:this method minimizes waiting time of public transfer,especially for public lines with large headways.
