Uhlelo lokulawula oluzenzakalelayo lwezibani zomgwaqo luyisihluthulelo sokufeza ukuhleleka kwezimoto. Izibani zomgwaqo ziyingxenye ebalulekile yezimpawu zomgwaqo kanye nolimi oluyisisekelo lwezimoto zomgwaqo.
Izibani zomgwaqo zakhiwe izibani ezibomvu (ezibonisa ukuthi akukho traffic), izibani eziluhlaza (ezibonisa ukuthi izimoto azikho), kanye nezibani eziphuzi (ezibonisa izixwayiso). Zihlukaniswe kanje: isibani sesignali yemoto, isibani sesignali esingeyona imoto, isibani sesignali sokuwela abahamba ngezinyawo, isibani sesignali yomzila, isibani sesignali yesiqondiso, isibani sesignali yesilumkiso esikhanyayo, isibani sesignali sokuwela izinga lomgwaqo nesitimela.
Izibani zomgwaqo ziyisigaba semikhiqizo yokuphepha emgwaqweni. Ziyithuluzi elibalulekile lokuqinisa ukuphathwa kwezimoto emgwaqweni, ukunciphisa izingozi zomgwaqo, ukuthuthukisa ukusebenza kahle kokusetshenziswa komgwaqo nokuthuthukisa izimo zezimoto. Zifanelekela izindawo ezihlanganayo njengeziphambano kanye nezindawo ezihlanganayo ezinobunjwa obungu-T. Zilawulwa umshini wokulawula isignali yezimoto zomgwaqo, ukuze izimoto kanye nabahamba ngezinyawo bakwazi ukudlula ngendlela ephephile nehlelekile.
Kungahlukaniswa ngokulawula isikhathi, ukulawula ukungeniswa kanye nokulawula okuguquguqukayo.
1. Ukulawula isikhathi. Isilawuli sesignali yethrafikhi endaweni yokuhlangana sisebenza ngokwesimiso sesikhathi esisethwe ngaphambilini, esaziwa nangokuthi ukulawula umjikelezo ojwayelekile. Leso esisebenzisa uhlelo lwesikhathi olulodwa kuphela ngosuku sibizwa ngokuthi ukulawula isikhathi kwesigaba esisodwa; leso esisebenzisa izinhlelo eziningana zesikhathi ngokwevolumu yethrafikhi yezikhathi ezahlukene sibizwa ngokuthi ukulawula isikhathi kwesigaba esiningi.
Indlela yokulawula eyisisekelo kakhulu ukulawula isikhathi sendawo eyodwa yokuhlangana. Ukulawulwa komugqa kanye nokulawulwa kwendawo nakho kungalawulwa ngesikhathi, okubizwa nangokuthi uhlelo lokulawula umugqa omile kanye nohlelo lokulawula indawo omile.
Okwesibili, ukulawula ukungenisa. Ukulawula ukungenisa kuyindlela yokulawula lapho kubekwa khona umshini wokuthola imoto emnyango wesiphambano, futhi uhlelo lwesikhathi sesignali yethrafikhi lubalwa yikhompyutha noma ikhompyutha ehlakaniphile yokulawula isignali, engashintshwa nganoma yisiphi isikhathi ngolwazi lokuhamba kwethrafikhi olutholwe umshini wokuthola. Indlela eyisisekelo yokulawula ukungenisa ukulawula ukungenisa kwesiphambano esisodwa, okubizwa ngokuthi ukulawula ukungenisa kokulawula kwephuzu elilodwa. Ukulawula ukungenisa kwephuzu elilodwa kungahlukaniswa kube ukulawula ukungenisa kwesigamu kanye nokulawula ukungenisa okuphelele ngokwezindlela ezahlukene zokusetha zomshini wokuthola.
3. Ukulawula okuguquguqukayo. Uma ithatha uhlelo lwethrafikhi njengohlelo olungaqinisekile, ingalinganisa isimo sayo ngokuqhubekayo, njengokuhamba kwethrafikhi, inani lokuma, isikhathi sokulibaziseka, ubude bomugqa, njll., iqonde kancane kancane futhi iqondise izinto, iziqhathanise nezici eziguquguqukayo ezifunwayo, bese isebenzisa umehluko ukubala Indlela yokulawula eshintsha amapharamitha alungisekayo ohlelo noma ikhiqize ukulawula ukuqinisekisa ukuthi umphumela wokulawula ungafinyelela ukulawula okuhle kakhulu noma okungaphansi kakhulu kungakhathaliseki ukuthi imvelo ishintsha kanjani.
