I-automatic command system yamarobhothi iwukhiye wokubona ukuhleleka kwethrafikhi. Amarobhothi ayingxenye ebalulekile yezimpawu zomgwaqo kanye nolimi oluyisisekelo lwethrafikhi yomgwaqo.
Amalambu ethrafikhi ahlanganisa amalambu abomvu (abonisa ukuthi akukho thrafikhi), amalambu aluhlaza (abonisa ithrafikhi evumayo), namalambu aphuzi (abonisa izixwayiso). Ihlukaniswe ngokuthi: ukukhanya kwesignali yemoto, ukukhanya kwesignali yemoto okungeyona eyemoto, ukukhanya kwesignali yabahamba ngezinyawo, ukukhanya kwesignali yomzila, ukukhanya kwesignali yesibonakaliso, ukukhanya kwesignali eyisixwayiso, ukukhanya komgwaqo kanye nezinga lesitimela.
Amarobhothi ayingxenye yemikhiqizo yokuphepha emgwaqweni. Ziyithuluzi elibalulekile lokuqinisa ukuphathwa kwezimoto emgwaqeni, ukunciphisa izingozi zomgwaqo, ukuthuthukisa ukusebenza kahle komgwaqo kanye nokwenza ngcono izimo zethrafikhi. Ilungele izimpambanomgwaqo njengeziphambano neziphambano ezimise okuka-T. Ilawulwa umshini wokulawula izimpawu zomgwaqo, ukuze izimoto nabahamba ngezinyawo bakwazi ukudlula ngendlela ephephile nehlelekile.
Ingahlukaniswa ngokulawula isikhathi, isilawuli sokungeniswa kanye nokulawula okuguquguqukayo.
1. Ukulawula isikhathi. Isilawuli sesignali yethrafikhi ezimpambanweni zomgwaqo sisebenza ngokuya ngohlelo lwesikhathi olusethiwe, olubuye lwaziwe njengokulawula umjikelezo ojwayelekile. Leyo esebenzisa uhlelo olulodwa lwesikhathi ngosuku ibizwa ngokuthi yi-single-stage timing control; leyo eyamukela amasu amaningana esikhathi ngokuya ngevolumu yethrafikhi yezikhathi ezihlukene ibizwa ngokuthi i-multi-stage timing control.
Indlela yokulawula eyisisekelo kakhulu ukulawula isikhathi komgwaqo owodwa. Ukulawula ulayini nokulawulwa kwendawo kungabuye kulawuleke ngokuhamba kwesikhathi, okubuye kubizwe ngokuthi i-static line control system kanye ne-static surface control system.
Okwesibili, ukulawulwa kokungeniswa. Ukulawulwa kokungeniswa kuyindlela yokulawula lapho umtshina wemoto ubekwe khona emnyango wempambanomgwaqo, futhi uhlelo lwesikhathi lwesignali yethrafikhi lubalwa ngekhompyutha noma ikhompyutha yokulawula isignali ehlakaniphile, engashintshwa noma nini ngolwazi lokugeleza kwethrafikhi olutholwa umtshina. Indlela eyisisekelo yokulawulwa kokungeniswa ukulawulwa kokungeniswa kwempambana-mgwaqo eyodwa, okubizwa ngokuthi isilawuli sokungeniswa sokulawula iphuzu elilodwa. Isilawuli sokungeniswa kwephuzu elilodwa singahlukaniswa ngokulawula kokungeniswa kwesigamu kanye nokulawulwa kokungeniswa okugcwele ngokwezindlela ezihlukene zokumisa zomtshina.
3. Ukulawula okuguquguqukayo. Ithatha isistimu yethrafikhi njengesistimu engaqinisekile, ingaqhubeka nokulinganisa isimo sayo, njengokugeleza kwethrafikhi, inombolo yezitobhi, isikhathi sokulibaziseka, ubude bomugqa, njll., kancane kancane iqonde futhi ibambe kahle izinto, iziqhathanise nezici eziguqukayo ezifiselekayo, futhi isebenzise umehluko ukubala Indlela yokulawula eshintsha amapharamitha alungisekayo wesistimu noma ekhiqiza isilawuli ukuze kuqinisekiswe ukuthi umphumela wokulawula ungafinyelela umgomo ofanele noma uguqule kahle endaweni.
