Njengamanje amarobhothi abomvu, aluhlaza futhi aphuzi. Okubomvu kusho ukuma, okuluhlaza kusho hamba, okuphuzi kusho ukulinda (okungukuthi ukulungiselela). Kodwa kudala, kwakunemibala emibili kuphela: obomvu noluhlaza. Njengoba inqubomgomo yokuguqulwa kwethrafikhi iqhubeka iphelele, kwanezelwa omunye umbala kamuva, ophuzi; Kwabe sekwengezwa elinye irobhothi. Ngaphezu kwalokho, ukwanda kombala kuhlobene eduze nokusabela kwengqondo yabantu kanye nesakhiwo esibonakalayo.
I-retina yomuntu iqukethe amaseli e-photoreceptor amise okwenduku kanye nezinhlobo ezintathu zamaseli e-photoreceptor amise okwekhoni. Amaseli e-photoreceptor amise okwenduku azwela kakhulu ekukhanyeni okuphuzi, kuyilapho izinhlobo ezintathu zamaseli e-photoreceptor amise okwekhoni zizwela ukukhanya okubomvu, ukukhanya okuluhlaza kanye nokukhanya okuluhlaza okwesibhakabhaka ngokulandelana. Ngaphezu kwalokho, ukwakheka kwabantu okubonakalayo kwenza kube lula kubantu ukuhlukanisa phakathi kokubomvu nokuluhlaza. Nakuba okuphuzi nokuluhlaza okwesibhakabhaka akunzima ukukuhlukanisa, ngenxa yokuthi amangqamuzana e-photoreceptor ebholeni lamehlo awazweli kangako ekukhanyeni okuluhlaza okwesibhakabhaka, okubomvu nokuluhlaza kukhethwa njengemibala yesibani.
Ngokuqondene nokubeka umthombo wombala wokukhanya kwethrafikhi, kukhona nesizathu esiqinile, okungukuthi, ngokomgomo we-optics ebonakalayo, ukukhanya okubomvu kunobude obude kakhulu nokudlulisa okunamandla, okukhanga kakhulu kunezinye izimpawu. Ngakho-ke, isethwe njengombala wesiginali yethrafikhi yethrafikhi. Ngokuqondene nokusetshenziswa kohlaza njengombala wesiginali yethrafikhi, kungenxa yokuthi umehluko phakathi kokuluhlaza nokubomvu mkhulu futhi kulula ukuwuhlukanisa, futhi i-coefficient eyimpumputhe yombala yale mibala emibili iphansi.
Ngaphezu kwalokho, kunezinye izici ngaphandle kwezizathu ezingenhla. Ngenxa yokuthi umbala ngokwawo unokubaluleka okungokomfanekiso, incazelo yombala ngamunye inezici zayo. Isibonelo, okubomvu kunikeza abantu uthando olunamandla noma umuzwa ojulile, olandelwa ophuzi. Kwenza abantu bazizwe beqaphile. Ngakho-ke, ingasethwa njengemibala yerobhothi ebomvu nephuzi enencazelo yokwenqabela ukuhamba kwezimoto nobungozi. Okuluhlaza kusho ukuthi mnene futhi kuthule.
Futhi okuluhlaza kunomphumela othile wokunciphisa ukukhathala kwamehlo. Uma ufunda izincwadi noma udlala ikhompuyutha isikhathi eside, nakanjani amehlo akho azozizwa ekhathele noma eshaywa umoya kancane. Ngalesi sikhathi, uma uphendulela amehlo akho ezitshalweni eziluhlaza noma izinto, amehlo akho ayoba nomuzwa ongalindelekile wenduduzo. Ngakho-ke, kufanelekile ukusebenzisa okuluhlaza njengombala wesiginali yethrafikhi ngokubaluleka kwethrafikhi.
Njengoba kushiwo ngenhla, umbala wesiginali yethrafikhi yasekuqaleni awusethwanga ngokungafanele, futhi kunesizathu esithile. Ngakho-ke, abantu basebenzisa okubomvu (okubonisa ingozi), okuphuzi (okumela isixwayiso sangaphambi kwesikhathi) kanye nohlaza (okubonisa ukuphepha) njengemibala yezimpawu zomgwaqo. Manje futhi iyaqhubeka nokusebenzisa futhi iqhubekele ohlelweni olungcono lwe-traffic order.
