高速公路熱熔劃線有70多種，按標劃方(fang)法可分(fen)為白色(se)虛(xu)線(xian)(xian)(xian)(xian)、白色(se)實(shi)線(xian)(xian)(xian)(xian)、黃色(se)虛(xu)線(xian)(xian)(xian)(xian)、黃色(se)實(shi)線(xian)(xian)(xian)(xian)、雙白虛(xu)線(xian)(xian)(xian)(xian)、雙白實(shi)線(xian)(xian)(xian)(xian)、雙黃虛(xu)線(xian)(xian)(xian)(xian)和黃色(se)虛(xu)實(shi)線(xian)(xian)(xian)(xian)等(deng)；按作(zuo)用(yong)又可分(fen)為車(che)行(xing)道中心線(xian)(xian)(xian)(xian)、車(che)道分(fen)界線(xian)(xian)(xian)(xian)、停止線(xian)(xian)(xian)(xian)、減速讓行(xing)線(xian)(xian)(xian)(xian)、人行(xing)橫(heng)道線(xian)(xian)(xian)(xian)、導流線(xian)(xian)(xian)(xian)、導向箭頭和左(zuo)轉彎導向線(xian)(xian)(xian)(xian)等(deng)；按功能則僅分(fen)為三類：一(yi)是指示標線(xian)(xian)(xian)(xian)，二是禁(jin)止標線(xian)(xian)(xian)(xian)，三是警告標線(xian)(xian)(xian)(xian)。

高速(su)公路熱(re)熔(rong)劃(hua)線(xian)(xian)(xian)(xian)(xian)由標劃(hua)于路面的各種線(xian)(xian)(xian)(xian)(xian)條、箭頭(tou)、文字以及立體標記、突起路標和(he)(he)(he)路邊線(xian)(xian)(xian)(xian)(xian)輪廓標記等構成的交(jiao)(jiao)通(tong)信號(hao)設施。 道路交(jiao)(jiao)通(tong)標線(xian)(xian)(xian)(xian)(xian)的作用是(shi)使(shi)機動車(che)、非(fei)機動車(che)和(he)(he)(he)行(xing)(xing)人分隔，提(ti)高道路利用率，減(jian)少或防止(zhi)(zhi)交(jiao)(jiao)通(tong)事故發生，并(bing)與交(jiao)(jiao)通(tong)標志(zhi)、交(jiao)(jiao)通(tong)信號(hao)配合(he)使(shi)用，增加其有效性。 交(jiao)(jiao)通(tong)標線(xian)(xian)(xian)(xian)(xian)有70多種，按標劃(hua)方法可分為白色(se)虛(xu)(xu)線(xian)(xian)(xian)(xian)(xian)、白色(se)實(shi)(shi)線(xian)(xian)(xian)(xian)(xian)、黃(huang)色(se)虛(xu)(xu)線(xian)(xian)(xian)(xian)(xian)、黃(huang)色(se)實(shi)(shi)線(xian)(xian)(xian)(xian)(xian)、雙(shuang)白虛(xu)(xu)線(xian)(xian)(xian)(xian)(xian)、雙(shuang)白實(shi)(shi)線(xian)(xian)(xian)(xian)(xian)、雙(shuang)黃(huang)虛(xu)(xu)線(xian)(xian)(xian)(xian)(xian)和(he)(he)(he)黃(huang)色(se)虛(xu)(xu)實(shi)(shi)線(xian)(xian)(xian)(xian)(xian)等；按作用又(you)可分為車(che)行(xing)(xing)道中心(xin)線(xian)(xian)(xian)(xian)(xian)、車(che)道分界線(xian)(xian)(xian)(xian)(xian)、停止(zhi)(zhi)線(xian)(xian)(xian)(xian)(xian)、減(jian)速(su)讓行(xing)(xing)線(xian)(xian)(xian)(xian)(xian)、人行(xing)(xing)橫道線(xian)(xian)(xian)(xian)(xian)、導流線(xian)(xian)(xian)(xian)(xian)、導向箭頭(tou)和(he)(he)(he)左轉彎導向線(xian)(xian)(xian)(xian)(xian)等；按功能則僅(jin)分為三類：一(yi)是(shi)指示標線(xian)(xian)(xian)(xian)(xian)，二(er)是(shi)禁止(zhi)(zhi)標線(xian)(xian)(xian)(xian)(xian)，三是(shi)警告標線(xian)(xian)(xian)(xian)(xian)。
