交通標(biao)(biao)線(xian)(xian)(xian)(xian)(xian)有70多種，按(an)標(biao)(biao)劃方法可分(fen)(fen)(fen)(fen)為白色(se)(se)虛(xu)線(xian)(xian)(xian)(xian)(xian)、白色(se)(se)實(shi)線(xian)(xian)(xian)(xian)(xian)、黃色(se)(se)虛(xu)線(xian)(xian)(xian)(xian)(xian)、黃色(se)(se)實(shi)線(xian)(xian)(xian)(xian)(xian)、雙白虛(xu)線(xian)(xian)(xian)(xian)(xian)、雙白實(shi)線(xian)(xian)(xian)(xian)(xian)、雙黃虛(xu)線(xian)(xian)(xian)(xian)(xian)和黃色(se)(se)虛(xu)實(shi)線(xian)(xian)(xian)(xian)(xian)等；按(an)作用(yong)又可分(fen)(fen)(fen)(fen)為車(che)行(xing)(xing)(xing)道中心(xin)線(xian)(xian)(xian)(xian)(xian)、車(che)道分(fen)(fen)(fen)(fen)界線(xian)(xian)(xian)(xian)(xian)、停止(zhi)線(xian)(xian)(xian)(xian)(xian)、減速讓(rang)行(xing)(xing)(xing)線(xian)(xian)(xian)(xian)(xian)、人行(xing)(xing)(xing)橫道線(xian)(xian)(xian)(xian)(xian)、導(dao)流線(xian)(xian)(xian)(xian)(xian)、導(dao)向箭(jian)頭(tou)和左(zuo)轉彎導(dao)向線(xian)(xian)(xian)(xian)(xian)等；按(an)功能(neng)則僅分(fen)(fen)(fen)(fen)為三類：一是指(zhi)示標(biao)(biao)線(xian)(xian)(xian)(xian)(xian)，二是禁止(zhi)標(biao)(biao)線(xian)(xian)(xian)(xian)(xian)，三是警告標(biao)(biao)線(xian)(xian)(xian)(xian)(xian)。

交(jiao)通標(biao)(biao)線(xian)(xian)(xian)(xian)，是(shi)(shi)指由標(biao)(biao)劃(hua)(hua)于路(lu)(lu)面的(de)各種線(xian)(xian)(xian)(xian)條、箭頭、文字以及(ji)立體(ti)標(biao)(biao)記、突起路(lu)(lu)標(biao)(biao)和路(lu)(lu)邊線(xian)(xian)(xian)(xian)輪廓標(biao)(biao)記等構成(cheng)的(de)交(jiao)通信號(hao)設施。 道路(lu)(lu)交(jiao)通標(biao)(biao)線(xian)(xian)(xian)(xian)的(de)作用(yong)是(shi)(shi)使機動車(che)、非(fei)機動車(che)和行(xing)(xing)人(ren)分隔(ge)，提高道路(lu)(lu)利用(yong)率，減少或防止交(jiao)通事(shi)故發生(sheng)，并與交(jiao)通標(biao)(biao)志、交(jiao)通信號(hao)配合(he)使用(yong)，增加其有效(xiao)性。 交(jiao)通標(biao)(biao)線(xian)(xian)(xian)(xian)有70多種，按標(biao)(biao)劃(hua)(hua)方法可分為白(bai)色虛線(xian)(xian)(xian)(xian)、白(bai)色實(shi)(shi)線(xian)(xian)(xian)(xian)、黃(huang)色虛線(xian)(xian)(xian)(xian)、黃(huang)色實(shi)(shi)線(xian)(xian)(xian)(xian)、雙(shuang)白(bai)虛線(xian)(xian)(xian)(xian)、雙(shuang)白(bai)實(shi)(shi)線(xian)(xian)(xian)(xian)、雙(shuang)黃(huang)虛線(xian)(xian)(xian)(xian)和黃(huang)色虛實(shi)(shi)線(xian)(xian)(xian)(xian)等；按作用(yong)又可分為車(che)行(xing)(xing)道中心線(xian)(xian)(xian)(xian)、車(che)道分界線(xian)(xian)(xian)(xian)、停止線(xian)(xian)(xian)(xian)、減速讓行(xing)(xing)線(xian)(xian)(xian)(xian)、人(ren)行(xing)(xing)橫道線(xian)(xian)(xian)(xian)、導流線(xian)(xian)(xian)(xian)、導向(xiang)(xiang)箭頭和左轉彎導向(xiang)(xiang)線(xian)(xian)(xian)(xian)等；按功能則僅分為三類：一是(shi)(shi)指示標(biao)(biao)線(xian)(xian)(xian)(xian)，二(er)是(shi)(shi)禁止標(biao)(biao)線(xian)(xian)(xian)(xian)，三是(shi)(shi)警告標(biao)(biao)線(xian)(xian)(xian)(xian)。
