Izibane zendlela zikhona ukuze zenze izithuthi ezidlulayo zibe nocwangco ngakumbi, kwaye ukhuseleko lwendlela luqinisekisiwe. Izixhobo zayo zinemiqathango ethile. Ukuze zisazise ngakumbi ngale mveliso, inani lezixhobo zesignali yendlela liyaziswa.
Iimfuneko zenani lezixhobo zesignali yethrafikhi
1. Xa umgama phakathi komgca wokupaka ongenisiweyo kunye nomqondiso wendlela ochaseneyo ungaphezulu kweemitha ezingama-50, kufuneka kongezwe ubuncinane iqela elinye emnyango; xa umgama phakathi komgca wokupaka ongenisiweyo kunye nonobumba ochaseneyo ungaphezulu kweemitha ezingama-70, kuya kukhethwa iyunithi ekhupha ukukhanya ehambelanayo. Ubungakanani bomphezulu okhanyayo yi-φ400mm.
2. Isixhobo sesignali yendlela sineendlela ezininzi ezibonisiweyo kwiqela lesignali yendlela ekuphumeni. Xa indlela ebonisiweyo ingekho phakathi kwezi ndlela zintathu zilandelayo ukusuka kumgca wokupaka ukuya kumgca wokupaka, iqela elinye okanye ngaphezulu kufuneka longezwe ngokufanelekileyo.
