1.定時控制
交叉(cha)口交通信(xin)號(hao)控(kong)(kong)制(zhi)(zhi)機均按(an)事先設(she)定的(de)(de)(de)配時(shi)(shi)方(fang)(fang)案運行，也稱(cheng)定周期控(kong)(kong)制(zhi)(zhi)。一(yi)天只用一(yi)個(ge)配時(shi)(shi)方(fang)(fang)案的(de)(de)(de)稱(cheng)為(wei)(wei)單段式(shi)定時(shi)(shi)控(kong)(kong)制(zhi)(zhi)；一(yi)天按(an)不同(tong)時(shi)(shi)段的(de)(de)(de)交通量采用幾個(ge)配時(shi)(shi)方(fang)(fang)案的(de)(de)(de)稱(cheng)為(wei)(wei)多段式(shi)定時(shi)(shi)控(kong)(kong)制(zhi)(zhi)。最基本(ben)的(de)(de)(de)控(kong)(kong)制(zhi)(zhi)方(fang)(fang)式(shi)是單個(ge)交叉(cha)口的(de)(de)(de)定時(shi)(shi)控(kong)(kong)制(zhi)(zhi)。線控(kong)(kong)制(zhi)(zhi)、面控(kong)(kong)制(zhi)(zhi)也都(dou)可用定時(shi)(shi)控(kong)(kong)制(zhi)(zhi)的(de)(de)(de)方(fang)(fang)式(shi)，也叫靜(jing)(jing)態線控(kong)(kong)系統、靜(jing)(jing)態面控(kong)(kong)系統。
2.感應控制
感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)是在交(jiao)叉口進(jin)口道上(shang)設置(zhi)車(che)輛檢測器，交(jiao)通信號(hao)燈配(pei)時方案由計(ji)算(suan)機或智能(neng)化信號(hao)控(kong)(kong)(kong)制(zhi)(zhi)機計(ji)算(suan)，可(ke)隨(sui)(sui)檢測器檢測到(dao)的車(che)流信息(xi)而隨(sui)(sui)時改變的一種控(kong)(kong)(kong)制(zhi)(zhi)方式。感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)的基本(ben)方式是單(dan)個交(jiao)叉口得(de)感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)，簡稱單(dan)點控(kong)(kong)(kong)制(zhi)(zhi)感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)。單(dan)點感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)隨(sui)(sui)檢測器設置(zhi)方式的不(bu)同可(ke)分為半(ban)感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)和全感應(ying)控(kong)(kong)(kong)制(zhi)(zhi)。
3.自適應控制
把交通(tong)系(xi)統作為(wei)一個(ge)不確定系(xi)統，能夠連(lian)續(xu)測量其狀態，如車(che)流量、停車(che)次數、延誤時間(jian)、排隊長(chang)度等，逐漸(jian)了解(jie)和掌握(wo)對象(xiang)，把他們與(yu)希望的動態特(te)性進行(xing)比(bi)較，并利用差值以改(gai)變(bian)系(xi)統的可調參數或產生一個(ge)控(kong)制(zhi)，從(cong)而保證(zheng)不論環境如何變(bian)化(hua)，均可使(shi)控(kong)制(zhi)效果達到最優或次優控(kong)制(zhi)的一種(zhong)控(kong)制(zhi)方式。
