针对地铁站台候车乘客行为规律的相关研究发现，候车乘客的分布与站台进出口位置息息相关，乘客更容易停留在进口位置。另外，由于地铁车厢信息不透明，候车乘客分布与对应车厢的乘客密度往往不相匹配，随着地铁客流的快速增长，乘车拥挤以及时空资源浪费等问题日益突出。针对上述问题，本文提出了使用阵列布置的压力传感器实时检测车厢乘客密度进而实现客流诱导的方法。系统工作时首先对列车各车厢内乘客的压力进行实时采集，再通过建立的乘客压力与车厢拥挤程度模型来判断各车厢的拥挤等级，并利用诱导显示屏和指示灯来告知候车乘客各车厢内的拥挤程度，使候车乘客选择合理上车位置，最终实现对候车客流的有效诱导，减轻了候车拥挤问题，提高了地铁运行效率。
According to the research on the behavior of waiting passengers on subway platform, it is found that the distribution of waiting passengers is closely related to the location of platform entrance and exit, and passengers are more likely to stay in the entrance position. In addition, the distribution of waiting passengers often does not match the passenger density of the corresponding carriage because of the opaque information of the subway carriage. With the rapid growth of subway passenger flow, the problems of traffic congestion and waste of space-time resources become increasingly prominent. In order to solve the above problems, this paper proposes a method to detect the passenger density in real time by using pressure sensors arranged in array. The system first collects the passenger pressure in each compartment of the train in real time, then judges the congestion level of each compartment by establishing the model of passenger pressure and the congestion degree of the compartment, and informs the waiting passengers of the congestion degree in each compartment by using the guidance display screen and the indicator lamp, so as to make the waiting passengers choose the reasonable boarding position. Finally, the system realizes the effective induction of waiting passenger flow, thus alleviating the problem of waiting congestion and improving the efficiency of subway operation.
