车身22米立体巴士"巴铁"将首秀 只跑300米

2016-06-27 14:35:41   央视网

第四,巴铁身长60米左右,转弯的问题怎么解决?公路不可能像铁路那样有大弧线式的转弯,巴铁体量这么大,小半径转弯就成了问题。实际上,大型车在转弯的时候,前轮与后轮所划过的是两个完全不同的半弧。对于完全自由的橡胶轮车这当然不是问题,但是对于要求每个轮子都不能出轨的巴铁这就成了问题。

最后一点,也是最为重要的就是安全问题。巴铁上面人员密集、距离地面2米多高,一旦出了事情,比如火灾、交通事故,乘客逃生就非常困难。如果把整个车厢放下,下方有其他车辆,后果不堪设想。

交通专家告诉北青报记者,因为涉及到公共安全问题,所以国家车辆管理比较严格,对生产企业实行准入制度,在工信部、发改委那里要取得资质,产品要经过工信部审查,要符合国家标准,审完以后才可以生产,并纳入工信部的目录,纳入正常渠道之后,“我们才能讨论其安全问题”。

巴铁到底是什么?

巴铁到底是个什么东西?据巴铁官网介绍,巴铁又叫立体快巴,是一种采用电力驱动的新型大运量公共交通工具,我国原创发明。车身分为四节,每节长12米,可谓是公交巨无霸。车体设计长度为58至62米,宽度7.8米,行驶时需横跨两条机动车道。分上下两层,上层可载客1200至1400人,下层镂空,镂空底层高度为2.1至2.2米,2米以下的小汽车可自由通行。

巴铁设计者说,巴铁的优势之一是减少拥堵。利用空中资源,可以避免现有传统公交车与小汽车争路的现状,如同一辆在公路上奔跑的宽体短型列车,最高时速可达每小时60公里,平均时速为每小时40公里。优势之二是载客量大。按照每辆巴铁每小时平均载客800人次,运行17小时(5:30—22:30)计算,每辆巴铁载客人数约13600人次,载人数量是普通公交大巴的几十倍。优势之三是巴铁拥有创造70万亿的投资需求。优势之四是成本低。地铁每公里造价约6亿元人民币,巴铁每公里造价为1.2亿元,仅为地铁的20%。另外,地铁施工周期为5至6年,而同等公里数的巴铁,施工周期为1年。
