近日，隨著重慶(qing)地鐵五(wu)號(hao)(hao)線(xian)一期(qi)信(xin)號(hao)(hao)系統(tong)互(hu)聯(lian)互(hu)通(tong)(tong)交(jiao)叉測試的成功，裝(zhuang)備(bei)中(zhong)國(guo)通(tong)(tong)號(hao)(hao)完(wan)全(quan)自主CBTC信(xin)號(hao)(hao)系統(tong)的重慶(qing)軌道交(jiao)通(tong)(tong)5號(hao)(hao)線(xian)率(lv)先具備(bei)互(hu)聯(lian)互(hu)通(tong)(tong)條(tiao)件(jian)，標志著由(you)中(zhong)國(guo)通(tong)(tong)號(hao)(hao)打造的全(quan)球首條(tiao)互(hu)聯(lian)互(hu)通(tong)(tong)地鐵即將孕育而(er)生。

長期以來，由于不同地鐵(tie)線路車(che)(che)載(zai)信(xin)號設備與地面信(xin)號設備間無法“交流(liu)”，導致列車(che)(che)跨(kua)線運(yun)行一(yi)(yi)直是一(yi)(yi)項世(shi)界性(xing)(xing)難題，國(guo)外曾(ceng)努力嘗(chang)試但始終(zhong)沒(mei)有(you)實現不同廠家間的(de)(de)地鐵(tie)信(xin)號系(xi)統(tong)互通(tong)(tong)。在我國(guo)，隨著(zhu)以中國(guo)通(tong)(tong)號CBTC信(xin)號系(xi)統(tong)為(wei)代(dai)表的(de)(de)自主知識產權(quan)信(xin)號系(xi)統(tong)的(de)(de)成熟應用(yong)，我國(guo)已編(bian)制出(chu)了適(shi)應中國(guo)國(guo)情的(de)(de)互聯(lian)互通(tong)(tong)技術標準(zhun)，真正(zheng)意(yi)義上建立了不同廠家之(zhi)(zhi)間、車(che)(che)載(zai)信(xin)號系(xi)統(tong)與地面信(xin)號系(xi)統(tong)之(zhi)(zhi)間，互相(xiang)兼容、互相(xiang)“交流(liu)”的(de)(de)基礎，一(yi)(yi)舉解(jie)決了這個世(shi)界性(xing)(xing)難題。地鐵(tie)互聯(lian)互通(tong)(tong)后，可以滿足乘客一(yi)(yi)站(zhan)式“直達”的(de)(de)需求，減少客流(liu)換乘壓力，降低地鐵(tie)建成本(ben)資，大(da)幅度提高(gao)車(che)(che)輛(liang)利用(yong)率(lv)和運(yun)營(ying)效率(lv)。
