Zifakwa njani iipali zezibane zendlela kunye neempawu zendlela?

Indawo yokufakelwa kweipali yesibane sendlelaKunzima kakhulu kunokufaka nje ipali engacwangciswanga. Yonke isentimitha yomahluko wobude iqhutywa zizinto zesayensi zokhuseleko. Makhe sijonge namhlanje ngeumenzi weepali zezibane zendlela zikamasipalaQixiang.

Ukuphakama kweSignali yePole

Ukuphakama kwesiginali kumisela ngokuthe ngqo ukuba abathathi-nxaxheba bezithuthi banokuyibona ngokucacileyo na isiginali. I-"Road Traffic Signal Light Setup and Installation Specifications" yesizwe yahlula ngokucacileyo phakathi kwezi nkalo zimbini:

Izibane zemiqondiso yesithuthi: Ukuphakama kokufakelwa kwe-cantilevered ukusuka kwi-5.5 ukuya kwi-7 yeemitha kuqinisekisa ukubonakala okucacileyo kubaqhubi ukusuka kumgama weemitha ezili-100. Ukufakelwa kweepali kufuna ukuphakama kweemitha ezi-3 nangaphezulu kwaye kusetyenziswa ikakhulu kwiindlela zesibini okanye kwiindawo ezidibana kuzo ezinomthamo omncinci wezithuthi.

Izibane zesignali ezingezizo ezemoto: Ukuphakama okufanelekileyo yi-2.5 ukuya kwi-3 yeemitha, kumgangatho wamehlo wabakhweli beebhayisekile. Ukuba zifakwe kwipali yemoto, i-cantilever kufuneka yolulwe ngaphezu kwendlela engezizo ezemoto.

Imiqondiso yokuwela abahambi ngeenyawo: Kufuneka yehliswe ibe ziimitha ezi-2 ukuya kwezi-2.5 ukuqinisekisa ukubonakala kwabahambi ngeenyawo (kuquka abantwana kunye nabasebenzisi bezitulo ezinamavili). Kwiindawo ezinqumlanayo ezibanzi kuneemitha ezingama-50, kufuneka kufakwe ezinye iiyunithi zokukhanya kwemiqondiso kwindawo yokuphuma.

Indawo yeSignal Pole

Ukukhethwa kwendawo ye-signal pole kuchaphazela ngokuthe ngqo ukugqunywa kwe-signal kunye nokubonakala kwayo:

1. Iindlela ezinezithuthi ezixubileyo kunye nezithuthi zabahambi ngeenyawo

Ipali yesignali kufuneka ibekwe kufutshane nendawo edibana kuyo udonga, kungcono ukuba ibe kwicala lasekunene. Kwiindlela ezibanzi, iiyunithi zesignali ezongezelelweyo zingongezwa kwicala lasekhohlo. Kwiindlela ezimxinwa (ububanzi obupheleleyo bungaphantsi kweemitha ezili-10), ipali yesignali yenxalenye enye ingabekwa kwicala lasekunene.

2. Iindlela ezineendlela ezahlukeneyo zezithuthi kunye neendlela zabahambi ngeenyawo

Ukuba ububanzi obuphakathi buyavuma, ipali yesignali kufuneka ibekwe ngaphakathi kweemitha ezi-2 ukusuka kwindawo edibana kuyo indlela yasekunene kunye nomda wendlela yabahambi ngeenyawo. Kwiindlela ezibanzi, iiyunithi zesignali ezongezelelweyo zingongezwa kwindlela yasekhohlo. Ukuba ipali yesignali incinci kakhulu, ipali yesignali kufuneka ibuyele kwindlela yasekhohlo.

Umthetho weSinyithi: Akukho naphantsi kwaziphi na iimeko apho iipali zesignali mazihlale kwindlela engaboniyo!

Nokuba iimfuno zokuphakama ziyafezekiswa, izibane zendlela zisenokuvalwa:

1. Akukho mithi okanye imiqobo engaphezulu komda osezantsi wokukhanya enokuthi ibekwe ngaphakathi kweemitha ezingama-50 ukusuka ekukhanyeni.

2. I-axis yesalathiso sesibane sesignali mayingaphazanyiswa ngaphakathi kwerediyasi engama-20°.

3. Imithombo yokukhanya ebangela ukudideka, njengezibane ezinemibala okanye iibhodi zentengiso, ayivumelekanga ngokungqongqo ukuba ibekwe emva kwesibane.

Uyilo lweempawu zendlela kunye nemigaqo yendawo kunye nemiqathango yile ilandelayo:

Indawo: Ngokuqhelekileyo ifumaneka kwicala lasekunene lendlela okanye ngaphezulu kwendlela, kodwa inokuba kufutshane okanye kumacala omabini, kuxhomekeke kwimeko. Isilumkiso, uthintelo, kunye neempawu zemiyalelo akufuneki zibekwe ecaleni. Ukuba zibekwe ecaleni, kufuneka zicwangciswe ngokulandelelana "kokuthintela → umyalelo → isilumkiso," ukusuka phezulu ukuya ezantsi kunye ukusuka ekhohlo ukuya ekunene. Ukuba kufuneka izibonakaliso ezininzi kwindawo enye, akufuneki kusetyenziswe ezingaphezu kwezine, kwaye uphawu ngalunye kufuneka lube nendawo eyaneleyo.

Imigaqo yoYilo: Ulwazi kufuneka luqhubeke kwaye lungaphazanyiswa, kwaye ulwazi olubalulekileyo lunokuphindwa. Ukubekwa kwezibonakaliso kufuneka kudityaniswe nothungelwano lwendlela olujikelezileyo kunye nemeko yezithuthi kwaye kulungelelaniswe nezinye izibonelelo ukuqinisekisa ukubonakala. Iimpawu kufuneka ziphephe ukuphazanyiswa yimithi, izakhiwo, kunye nezinye izakhiwo kwaye akufuneki ziphule imida yokwakhiwa kwendlela. Iimeko ezikhethekileyo: Iimpawu ezindleleni ezinkulu nakwiindlela ezinkulu zasezidolophini kufuneka zihambelane ne-“Iimpawu zeNdlelakunye neempawu” kwaye zibonelela ngolwazi olucacileyo. Imiqondiso kwiindawo ezikhethekileyo zendlela, njengeetonela kunye neebhulorho, kufuneka ilungiselelwe ngokweempawu zendawo kwaye iqinisekise ukubonakala.
