Ukuphathwa kwethrafikhi kuyisici esibalulekile sokuhlela amadolobha, okuqinisekisa ukuhamba kahle kwezimoto, abahamba ngezinyawo, nabahamba ngamabhayisikili emigwaqweni. Ukuze kulawulwe kahle ithrafikhi, elinye lamathuluzi abalulekile asetshenziswayo amarobhothi. Phakathi kwezinhlobo ezahlukene zezimpawu zomgwaqo,Izigaba ze-4 zezinhlelo zezimpawu zomgwaqodlala indima ebalulekile ekulawuleni ukuphambana kwemigwaqo kanye nokulawula ithrafikhi ezindaweni zasemadolobheni eziguqukayo. Kule bhulogi, sizocubungula ubunkimbinkimbi bezimpawu zethrafikhi zesigaba esi-4 futhi siqonde umqondo wesigaba sezinhlelo zezimpawu zomgwaqo.
1. Liyini irobhothi?
Ngaphambi kokuthi singene emininingwaneni yezigaba ezi-4 zamarobhothi, ake sakhe isisekelo esiqinile ngokuqala siqonde imiqondo eyisisekelo yamarobhothi. Amalambu omgwaqo amadivayisi afakwe ezimpambanweni zomgwaqo ukuze alawule ilungelo lendlela lokugeleza kwethrafikhi okuhlukile. Baxhumana ngezinkomba ezibukwayo ezifana nezibani ezibomvu, ezinhlaka, neziluhlaza ukuze kuqinisekiswe ukunyakaza okuphephile nokusebenzayo kwezimoto, abahamba ngezinyawo nabagibeli bamabhayisikili.
2. Qonda isigaba samasignali omgwaqo:
Kumasistimu wamasignali omgwaqo, “isigaba” sisho isikhathi esithile lapho ithrafikhi igeleza ngendlela ethile noma indlela ethile. Umgwaqo ngamunye ngokuvamile unezigaba eziningi, okuvumela ukunyakaza okuhlukahlukene ukuthi kwenzeke ngezikhathi ezihlukene. Ukuxhumana okusebenzayo kwalezi zigaba kuqinisekisa ukuhamba kahle kwethrafikhi futhi kunciphisa ukuminyana.
3. Isingeniso sezigaba ezi-4 zezimpawu zomgwaqo:
Isistimu yesignali yethrafikhi yesigaba esi-4 iwumklamo owamukelwa kabanzi ohlinzeka ngezikhathi ezine ezihlukene zokunyakaza okuhlukile empambanweni yomgwaqo. Le mikhankaso ihlanganisa izigaba ezilandelayo:
A. Isiteji esiluhlaza:
Phakathi nesigaba esiluhlaza, izimoto ezihamba ngendlela ethile noma isiqondiso zinikezwa ilungelo lendlela. Lokhu kuvumela ithrafikhi ukuthi ihambe ngendlela ehlelekile ngaphandle kokungqubuzana nezimoto kwezinye izinkomba.
B. Isigaba esiphuzi:
Isigaba esiphuzi sisebenza njengenkathi yenguquko, ebonisa kumshayeli ukuthi isigaba samanje siyaphela. Abashayeli bayelulekwa ukuthi bazilungiselele ukuma njengoba ilambu lizoshintsha libe bomvu ngokushesha.
C. Isigaba esibomvu:
Phakathi nesigaba esibomvu, izimoto ezivela endaweni ethile kufanele zime ngokuphelele ukuze zivumele ukuhamba okuphephile kwezinye izindawo.
D. Isigaba esibomvu esigcwele:
Isigaba esibomvu klebhu isikhawu esifushane lapho zonke izibani ezimpambanweni zomgwaqo ziba bomvu ukuze zisule ngokuphephile noma yiziphi izimoto ezisele noma abahamba ngezinyawo ngaphambi kokuthi kuqale isigaba esilandelayo.
4. Izinzuzo zesistimu yesignali yethrafikhi yezigaba ezi-4:
Ukusebenzisa uhlelo lwesignali yethrafikhi yesigaba esi-4 kunikeza izinzuzo eziningi, okuhlanganisa:
A. Ukugeleza kwethrafikhi okuthuthukisiwe:
Ngokunikeza izikhawu zesikhathi ezihlukene zokunyakaza okuhlukile, amasignali ethrafikhi ezigaba ezi-4 athuthukisa ukugeleza kwethrafikhi, anciphisa ukuminyana, futhi anciphise ukubambezeleka.
B. Thuthukisa ukuphepha:
Ukuxhumana okusebenzayo kwezigaba kusistimu yesignali yethrafikhi yesigaba esi-4 kuthuthukisa ukuphepha ezimpambanweni zomgwaqo ngokunciphisa izingxabano phakathi kwezimoto nokugeleza kwethrafikhi okuhlukile.
C. Idizayini efanele abahamba ngezinyawo:
Isistimu yesignali yethrafikhi yezigaba ezi-4 ibheka ukuphepha nokunethezeka kwabahamba ngezinyawo ngokuhlanganisa izigaba zabahamba ngezinyawo ezizinikele ukuze kuqinisekiswe amathuba okuwela aphephile.
D. Ijwayela kumavolumu ahlukene wethrafikhi:
Ukuvumelana nezimo kwamarobhothi esigaba esi-4 kuvumela ukulungiswa kumthamo wethrafikhi ohlukahlukene ngezikhathi ezihlukene zosuku, okuqinisekisa ukuphathwa kwethrafikhi okuphumelelayo ngaso sonke isikhathi.
Ekuphetheni
Kafushane, amasistimu wesignali yethrafikhi yezigaba ezi-4 adlala indima ebalulekile ekulawuleni ithrafikhi ezimpambanweni zomgwaqo kanye nokuqinisekisa ukuhamba kahle kwezimoto, abahamba ngezinyawo, nabahamba ngamabhayisikili. Ukuqonda umqondo wezigaba kumasignali wethrafikhi kubalulekile ekuqondeni ukuhlanganiswa okusebenzayo kokunyakaza kwethrafikhi. Ngokusebenzisa izimpawu zethrafikhi zezigaba ezi-4, abahleli bedolobha bangathuthukisa ukuhamba kwethrafikhi, bathuthukise ukuphepha, futhi bakhuthaze uhlelo lwezokuthutha oluvumelanayo ezindaweni zasemadolobheni.
