摘要:

地铁站台客流的顺利出站与换乘导向标识提供的有效引导服务关系密切.本文对地铁站台导向标识系统的布局优化方法进行了研究.首先根据导向标识的服务特点,提出了基于信息熵理论的标识引导服务效能的计算方法,考虑到乘客与导向标识的交互特点,以分段概率函数的形式表达乘客接受引导服务的过程;其次以导向标识协同服务效能最大为目标,建立了导向标识布局优化模型,证明简化后的模型是基于协同覆盖的选址模型,并设计启发式算法对模型求解.最后将该模型应用于站台出站导向标识布局优化中,优化后标识服务效能增加32.5%,引导范围增加39.16%.计算结果证明,该模型有效 提升了导向标识系统的服务效能,可以为更多乘客提供引导服务.

Abstract:

The smooth exit and transfer process of passengers flow on platform depends on the excellent guidance service provided by the signage system. This paper investigates the optimization method of the guidance signage system on metro platform. According to the service characteristic of guidance signage, we propose a calculation method of service efficacy and present a piece-wise probability function to explain the process of receiving the guidance service considering the interaction principle between passengers and guidance signage. Then the optimization model of guidance signage system configuration is proposed to realize the maximum service efficacy, and the simplified model is proved to be the cooperative covering location problem, which can be solved by the heuristic algorithm. At last, the proposed model is applied in the configuration optimization of exit guidance signage system on platform, the service efficacy of signage system increases by 32.5% and the coverage area increases by 39.16%. The calculation results show that the model can improve the whole guidance service efficacy of the guidance signage system and more passengers can receive the guidance service.
