Take Xian urban rail transit network planning for instance,the coordination between it is four pre - selection networks and urban form were analyzed These compositive coordination indexes of four pre 一 selection network were 0.782 9, 0.777 8, 0. 690 8, 0. 784 9, the computing results showed that the forth network is the best one.Key words： traffic engineering；rapid rail transit；network scheme；urban form；coordination；quantitative analysis国内外轨道交通线网建设和运营经验表明：轨道 交通运营比较成功的城市，其轨道线网的形态结构与 城市的空间形态都结合的比较成功，如汉堡、莫斯科等。轨道交通线路的建设有利于城市中心区人口的疏 散，减少市中心区人口密度，加快城市副中心、彷缘集 团以及卫星城镇的建设,使城市用地布局结构趋于合2008年11月第11期（总122；铁道工程学报JOURNAL OF RAILWAY ENGINEERING SOCIETYNov 2008NO.
