Izibani zethrafikhi ziyingxenye ebalulekile yezimpawu zomgwaqo kanye nolimi oluyisisekelo lwethrafikhi yomgwaqo. Izibani zethrafikhi zakhiwa izibani ezibomvu (azivunyelwe ukudlula), izibani eziluhlaza (eziphawulwe ngemvume), kanye nezibani eziphuzi (izixwayiso eziphawulwe). Zihlukaniswe ngalezi: izibani zezimpawu zezimoto, izibani zezibonakaliso ezingezona ezemoto, izibani zesibonakaliso sokuwela abahamba ngezinyawo, izibani zesibonakaliso somzila, izibani zesibonakaliso sesiqondiso, izibani zesibonakaliso sokukhanya okukhanyayo, izibani zesibonakaliso sokuwela indiza yomgwaqo neyesitimela.
Izibani zomgwaqo ziyisigaba semikhiqizo yokuphepha emgwaqweni. Ziyithuluzi elibalulekile lokuqinisa ukuphathwa kwezimoto emgwaqweni, ukunciphisa izingozi zomgwaqo, ukuthuthukisa ukusebenza kahle komgwaqo, kanye nokuthuthukisa izimo zezimoto. Zifanelekela izindawo eziphambanayo ezifana nokuwela kanye nohlobo lwe-T, futhi zilawulwa umshini wokulawula isignali yezimoto zomgwaqo ukusiza izimoto nabahamba ngezinyawo ukuba badlule ngokuphepha nangokuhlelekile.
Izinhlobo zezibani zomgwaqo zifaka phakathi: izibani zezimpawu zomgwaqo omkhulu, izibani zezibonakaliso zokuwela abahamba ngezinyawo (okungukuthi izibani zomgwaqo), izibani zezibonakaliso ezingezona izimoto, izibani zezinkomba zokuqondisa, izibani zezimoto ezihambayo, izibani zelanga, izibani zezibonakaliso, ama-toll booth.
