在快速发展的同时,北京地铁呈现出在建地铁工程多、运营里程长、客流量大、换乘站多、路网大客运量持续时间长等特点。地铁安全运营面临的挑战越来越多,地铁系统的安全风险越来越高,风险管控难度也越来越大。超大客运量常态化,考验城市安全治理能力。北京地铁日均客运量超1000万已成常态,大客流不仅冲击重要换乘车站,同时使新线与旧线运能不匹配的矛盾突出。设计标准低、标准不一致,存在安全隐患。早期线路建设标准等级、设计标准偏低,产品质量标准不高。目前地铁运营网络系统存在线路特征个性化、技术水平差异 At the same time of rapid development, the Beijing Subway has many features such as many subway projects under construction, long operating mileage, large passenger flow, more transfer stations and longer duration of large passenger traffic on the road network. More and more challenges are faced in the safe operation of the subway. The security risks of the subway system are getting higher and higher, and the risk control is also becoming more and more difficult. Super normal passenger volume, test the ability of urban safety management. The average daily passenger volume of Beijing Subway exceeds 10 million has become the norm. Large passenger flows not only impact important transfer stations, but also make the contradiction between the new line and the old line not matched. Low design standards, inconsistent standards, there are security risks. Early line construction standards, low design standards, product quality standards are not high. At present, the metro operation network system has the characteristics of individual lines and technical differences
