公交拥挤指数实时播报属于城市交通环境实时播报系统范畴。公交剩余座位、车内CO2浓度、车厢底部单位面积受力等信息可有效的反映当前公交内部的拥挤情况。针对目前交通系统中没有技术相对成熟的拥挤指数实时播报系统,提出了一种基于无线传感网的公交拥挤指数实时播报系统。系统分为无线传感器网络节点、SINK节点、终端分析评估系统和站台显示平台4个子模块,传感器网络节点实时采集公交内部运营环境数据,通过射频和GPRS无线通信模式将数据传递给终端评估系统分析并向该条公交线路的所有站台做出播报,方便出行市民选择最佳的交通线路。文章给出了系统的总体结构和4个子系统的软硬件设计,实现了城市公交内部运营环境的实时播报。

Real-time broadcast system of public transport crowding index belongs to the broadcast system of urban public transport environment.The remaining bus seats and CO2 concentration in bus can effectively reflect the current congestion of public transport.This paper proposes a real-time broadcast system about the crowding index in public tranport based on wireless sensor network.The system can be divided into four submodules： wireless sensor network node,sink node,terminal analysis and evaluation system and site display platform.Operating datas in public tranport collected by wireless sensor networking node are sent to terminal analysis and evaluation system by GPRS wireless communication mode.This system can help people choose the best line of traffic.
