Injongo ephambili yesigaba somqondiso we-traffic kukwahlula ngokufanelekileyo ukuhamba kwezithuthi eziphikisanayo okanye eziphazamisa kakhulu kunye nokunciphisa ungquzulwano lwezithuthi kunye nokuphazamiseka kwi-intersection.Uyilo lwesigaba sophawu lwetrafikhi linyathelo eliphambili lexesha lomqondiso, elimisela ubunzululwazi kunye nengqiqo yeskimu sexesha, kwaye lichaphazela ngokuthe ngqo ukhuseleko lwezithuthi kunye nokuguda kwendlela yokuhlangana.
Inkcazo yamagama anxulumene nezibane zendlela
1. Isigaba
Kumjikelo wesignali, ukuba enye okanye imijelo emininzi yetrafikhi ifumana umqondiso wombala ofanayo nangaliphi na ixesha, isigaba somqondiso esiqhubekayo esipheleleyo apho bafumana khona imibala eyahlukileyo yokukhanya (luhlaza, tyheli nobomvu) kuthiwa sisigaba somqondiso.Isigaba ngasinye somqondiso sitshintshana ngamaxesha athile ukuze sifumane umboniso wokukhanya okuluhlaza, oko kukuthi, ukufumana “ilungelo lendlela” kwindawo yokuhlangana.Uguqulo ngalunye lwe "ilungelo lendlela" libizwa ngokuba sisigaba somqondiso.Ixesha lomqondiso liqulunqwe sisimbuku salo lonke ixesha lexesha elibekwe kwangaphambili.
2. Umjikelo
Umjikelo ubhekisa kwinkqubo epheleleyo apho imibala yesibane eyahlukeneyo yesibane somqondiso iboniswa ngokujika.
3. Ungquzulwano lokuqukuqela kwezithuthi
Xa imijelo emibini yetrafikhi eneendlela ezahlukeneyo zokuhamba idlula kwindawo ethile kwisithuba ngaxeshanye, ungquzulwano lwezithuthi luya kwenzeka, kwaye le ngongoma ibizwa ngokuba yindawo yokungqubana.
4. Ukugcwalisa
Umlinganiselo womthamo wetrafikhi wangempela ohambelana nomzila ukuya kumthamo wezithuthi.
Umgaqo woyilo wesigaba
1. Umgaqo wokhuseleko
Ungquzulwano lokuhamba kwezithuthi phakathi kwezigaba kuya kuncitshiswa.Ukuqukuqela kwezithuthi ezingangqubaniyo kunokukhululwa kwisigaba esinye, kwaye ukuqukuqela kwezithuthi ezingqubanayo kuya kukhutshwa kwizigaba ezahlukeneyo.
2. Umgaqo osebenzayo
Uyilo lwesigaba kufuneka luphucule ukusetyenziswa kwexesha kunye nezixhobo zesithuba ekudibaneni kweendlela.Izigaba ezininzi kakhulu ziya kukhokelela ekwandeni kwexesha elilahlekileyo, ngaloo ndlela ukunciphisa umthamo kunye nokusebenza kakuhle kwetrafikhi ye-intersection.Amanqanaba ambalwa kakhulu anokunciphisa ukusebenza kakuhle ngenxa yongquzulwano olukhulu.
3. Umgaqo wokulinganisela
Uyilo lwesigaba kufuneka luthathele ingqalelo ibhalansi ye-saturation phakathi kwe-traffic flows kwicala ngalinye, kwaye ilungelo lendlela liya kwabiwa ngokufanelekileyo ngokuhambelana nokuhamba kwezithuthi ezahlukeneyo kwicala ngalinye.Kuya kuqinisekiswa ukuba umlinganiselo wokuhamba kwesikhokelo ngasinye sokuhamba ngaphakathi kwesigaba asifani kakhulu, ukuze ungachithi ixesha lokukhanya okuluhlaza.
4. Umgaqo wokuqhubekeka
Isikhokelo sokuhamba sinokufumana ubuncinci ixesha eliqhubekayo lokukhanya okuluhlaza kumjikelo;Zonke iindlela zokuhamba kwamanzi okungena ziya kukhululwa ngezigaba eziqhubekayo;Ukuba imijelo yetrafikhi emininzi yabelana ngendlela, kufuneka ikhululwe ngaxeshanye.Umzekelo, ukuba i-traffic edlulayo kunye ne-traffic ekhohlo yabelana ngendlela efanayo, kufuneka zikhutshwe ngaxeshanye.
5. Umgaqo wabahambi ngeenyawo
Ngokubanzi, abahambi ngeenyawo kufuneka bakhululwe kunye ne-traffic flow kwicala elinye ukunqanda impixano phakathi kwabahambi ngeenyawo kunye nezithuthi ezijikela ngasekhohlo.Kwiindlela ezinqumlayo ezinobude obude bokunqumla (obukhulu okanye bulingana ne-30m), ukuwela okwesibini kunokuphunyezwa ngokufanelekileyo.
