美媒对比中美地铁:纽约地铁常延误 上海地铁整点率99.8%

美媒称,纽约的通勤者经常遇到延误。宾夕法尼亚站老化的轨道在经历一系列脱轨事件后正在重建。整个地铁系统正在紧急状态下运行。而世界另一端的中国正在加速修建新的地铁系统。上海今年在修建三条新的地铁线。地铁几乎总是准点。

美国《纽约时报》网站8月14日刊登题为《借鉴纽约经验,上海地铁青出于蓝》的报道称,中国官员们常说纽约的公共交通网络是典范,虽然他们对它的效仿会侧重于某些方面。

上海地铁频率高且准时

虽然纽约的系统在老化,但它大胆的设计仍反映出最初创造者的雄心壮志——快速隧道和车站连接起十几条线路。上海的地铁干净、高效,还在不断延伸。不过,它的开发也反映出设计者最重要的考虑是控制庞大的人群,避免拥挤,所以它的布局会让旅程更长。

报道称,纽约地铁长期延误,一是因为机械故障,二是因为轨道上的垃圾,或者有人从站台上跌落。纽约开始对轨道垃圾进行密集清理,以减少火灾的频率。只有两条线路——列克星敦大街线和皇后大道线——能够每两分钟发一趟车,其他线路要慢得多。纽约的信号和切换设备大多都是在二战前安装的。

相比之下,上海的地铁不仅频率高,而且很可靠。据说,上海地铁的整点率高达99.8%。很少有人或垃圾掉入轨道:厚实、透明的强化玻璃墙将站台与轨道分开,滑动门仅在火车到站时开启。在最繁忙的路线上,火车每两分钟一趟,其他线路也几乎达到这个频率。

纽约的确有它的优势——尤其是对夜猫子来说。大都会运输署以它的472个地铁站全部每天24小时开放为荣。

上海乃至整个中国的地铁系统每天晚上停运。上海仅在数月前将其最繁忙路线的停运时间延长至午夜,而其他路线依然在晚上10点半停运。

上海地铁负责系统运行和管理中心的副总裁邵伟中表示,纽约地铁之所以能做到这样,是因为其建造者一个多世纪前的远见。纽约的地铁系统除了区域隧道之外,还修建了快速隧道。所以车厢可以在夜间轮流通过区域隧道和快速隧道,维修工作可以在未使用的隧道里进行。
