摘要
针对城市轨道交通客流量传统预警方法,客流监测不准确导致预警能力差的问题,研究城市轨道交通客流量监测仪极限预警方法。该方法利用轨道交通客流管理控制平台进行数据统计,以早晚出行高峰时间和特定时间为参照利用监测仪监测车站上行区间和下行区间中的上下车乘客人数,计算车站的最大客流承载量,根据运营线路中每一站点的上下车人数、剩余乘客数、中途车站进站乘客数和人群体貌特征设置候车区的极限预警值,根据楼梯电梯上客流的运动速率设置出站口的客流极限预警值,将监测仪进行预警等级划分,并用颜色表示客流拥堵的严重性,至此实现所提出的预警方法。实验结果表明:与传统预警方法相比,所提出的预警方法对于客流监测的准确率达到了95.5%,成功预警率为100%。由此可见,所提出的预警方法更能缓解客流量过大带给轨道交通的压力。
In view of the problem of poor early-warning ability caused by inaccurate monitoring of passenger flow in the traditional early-warning method of urban rail transit passenger flow,the limit early-warning method of urban rail transit passenger flow monitor is studied.The method use the rail transit passenger flow management control platform for data statistics,and the specific time to travel in the morning and evening rush hour as reference by monitoring station of the uplink and downlink interval boarding passengers,calculate the largest passenger flow volume of the stations according to the operation line in each site,the remaining passengers getting on or off the number,the way the station station passenger numbers and physical characteristics set waiting area population and limit warning value.According to the stairs on the elevator traffic movement speed settings exit passenger flow limit warning value,the warning level of the detector is divided,with color said the seriousness of the traffic congestion.So far the proposed early warning method is realized.The experimental results show that compared with the traditional early-warning method,the accuracy of the proposed early-warning method for passenger flow monitoring reaches 95.5%,and the successful early-warning rate is 100%.Thus it can be seen that the proposed early-warning method can alleviate the pressure brought by excessive passenger flow to rail transit.
