Njengoba sekusetshenziswe amalambu ajwayelekile kazwelonke emigwaqweni, adonse ukunaka kwabantu abaningi. Eqinisweni, izinga elisha likazwelonke lamalambu amasignali omgwaqo laqalwa kusukela ngomhlaka-1 Julayi 2017, okungukuthi, inguqulo entsha Yezicaciso Zokumiswa Nokufakwa Kwezibani Zesiginali Yethrafikhi Emgwaqeni elakhiwe iKomidi Likazwelonke Lokulawula Ukumisa. Kwaze kwaba yiminyaka emibili edlule lapho kwaqala khona ukusetshenziswa kwezimoto zomgwaqo. Izinga elisha lizohlanganisa imodi yokubonisa kanye nengqondo yamarobhothi ezweni lonke. Imodi yokuqala yokufunda yesibili nayo izothathelwa indawo ukukhanselwa kokufunda kwesibili nesikhumbuzi se-stroboscopic. Ngaphezu kwalokho, olunye ushintsho lwamarobhothi esilinganisweni esisha sezwe ukuthi aseshintshile esuka kugridi yasekuqaleni yesigodlo emithathu aya kugridi yesigodlo esiyisishiyagalolunye, anekholomu eqondile yamalambu ayindilinga phakathi nezinkomba zendlela nhlangothi zombili.
Ziningi izinzuzo zokukhansela ukubala wehla kwamarobhothi ezingeni elisha likazwelonke. Amarobhothi endabuko alula kakhulu, futhi amarobhothi ashintshwa ngokushintshana ngokwesikhathi esimisiwe, kungakhathaliseki ukuthi zingaki izimoto nabahamba ngezinyawo emgwaqeni. Kodwa manje ukukhanya kwesiginali yethrafikhi yendabuko akusasebenzi, ngoba akwenziwe ubuntu ngokwanele.
Isibonelo, amadolobha amaningi anezimilo ezimbi kakhulu zethrafikhi, ikakhulukazi ngezikhathi zejubane, futhi kulula ukuba ne-asymmetric traffic kuzo zombili izinhlangothi zomzila. Isibonelo, ngesikhathi sokuphumula, kukhona zonke izimoto endleleni eya ekhaya, kodwa cishe azikho izimoto ngakolunye uhlangothi. Noma phakathi kwamabili zimbalwa izimoto emgwaqeni, kodwa isikhathi samarobhothi asishintshi. Kungakhathaliseki ukuthi imoto ikhona noma cha, kusafanele silinde umzuzu owodwa noma emibili.
Ilambu lesignali yethrafikhi elithuthukisiwe liwuhlobo olusha lokukhanya kwesignali ehlakaniphile, elikwazi ukubona ukugeleza kwethrafikhi yesikhathi sangempela ezimpambanweni zomgwaqo futhi lihlaziye ngokuzenzakalelayo futhi lilungise imodi yokukhulula kanye nesikhathi esidlulayo sokukhanya kwesignali yesiqondiso ngasinye. Uma kunokugeleza okuncane kwethrafikhi ohlangothini olulodwa empambanweni yomgwaqo, isilawuli sesignali yethrafikhi esihlakaniphile sizoqeda ilambu eliluhlaza kuleyo ndawo kusenesikhathi, sikhulule eminye imizila enokugeleza kwethrafikhi enkulu, futhi sinciphise isikhathi sokulinda amalambu abomvu. Ngale ndlela, ukusebenza okudidiyelwe kwezimpambanondlela eziningi kungabonakala, ukusebenza kahle kwezimoto kuzo zonke izimpambanomgwaqo kungathuthukiswa, futhi ukuphambukisa okuhlakaniphile nokuminyana kwezimoto kungadamba.
