Ukususela ekubeni sele kusetyenziswe izibane ezisemgangathweni ezitsha zelizwe ezindleleni, ziye zatsala ingqalelo yabantu abaninzi.Enyanisweni, umgangatho omtsha welizwe lokukhanyisa izibane zendlela waphunyezwa ekuqaleni kwe-1 kaJulayi, i-2017, oko kukuthi, inguqu entsha yeNkcazo yokuSeta kunye noFakelo lweZibane zeSibonakaliso zeNdlela eziqulunqwe yiKomiti yoLawulo lweMigangatho yeSizwe.Akuzange kube yiminyaka emibini yokugqibela apho izithuthi ezindleleni zaqala ukuphunyezwa.Umgangatho omtsha uya kudibanisa indlela yokubonisa kunye nengqiqo yezibane zendlela kwilizwe lonke.Imowudi yokufunda yesibini yentsusa nayo iya kutshintshwa kwakhona kukucinywa kokufunda okwesibini kunye nesikhumbuzo sestroboscopic.Ukongeza, olunye utshintsho lwezibane zendlela kumgangatho omtsha wesizwe kukuba zitshintshile ukusuka kwigridi yebhotwe yantlandlolo emithathu ukuya kwigridi yebhotwe elithoba, kunye nekholamu ethe nkqo yezibane ezingqukuva phakathi kunye nezalathi zesalathiso kumacala omabini.
Zininzi izinto eziluncedo zokurhoxisa ukubala ukwehla kwezibane zendlela kumgangatho omtsha wesizwe.Izibane zendlela eziqhelekileyo zilula kakhulu, kwaye izibane zendlela ziguqulwa ngokutshintshana ngokuhambelana nexesha elimisiweyo, kungakhathaliseki inani lezithuthi kunye nabahamba ngeenyawo endleleni.Kodwa ngoku isibane sophawu lwetrafikhi asisebenzi, kuba asenziwanga ngumntu ngokwaneleyo.
Umzekelo, izixeko ezininzi zinee-traffic jams ezimandundu, ngakumbi kwiiyure zokuleqa, kwaye kulula ukuba ne-asymmetric traffic kumacala omabini endlela.Ngokomzekelo, ngexesha lokungabikho emsebenzini, kukho zonke iimoto endleleni egodukayo, kodwa akukho zimoto zingekho kwelinye icala.Okanye ezinzulwini zobusuku, zimbalwa iimoto endleleni, kodwa ixesha lezibane lisafana.Kungakhathaliseki ukuba kukho imoto okanye akunjalo, kusafuneka silinde umzuzu okanye emibini.
Ukuphuculwa kokukhanya kwe-traffic ukukhanya luhlobo olutsha lokukhanya komqondiso ohlakaniphile, onokubona ukuhamba kwexesha langempela kwi-traffic intersections kwaye uhlalutye ngokuzenzekelayo kwaye ulungelelanise imodi yokukhulula kunye nexesha elidlulayo lokukhanya kwesalathisi ngasinye.Ukuba kukho ukuhamba kancinci kwezithuthi kwicala elinye ekudibaneni kweendlela, umlawuli okrelekrele wemiqondiso yendlela uya kuphelisa isibane esiluhlaza ukuya kwelo cala kwangethuba, akhulule ezinye iindledlana ezineemoto ezinkulu, aze anciphise ixesha lokulinda izibane ezibomvu.Ngale ndlela, ukusebenza ngokulungelelanisiweyo kwee-intersections ezininzi kunokuphunyezwa, ukusebenza kakuhle kwezithuthi kwi-intersection yonke kunokuphuculwa, kwaye ukuphambuka okukrelekrele kunye nokuxinana kwezithuthi kunokupheliswa.
