Amalambu omgwaqo akhona ukwenza izimoto ezidlulayo zihleleke kakhudlwana, futhi nokuphepha kwethrafikhi kuqinisekisiwe. Imishini yayo inemibandela ethile. Ukuze usazise kabanzi ngalo mkhiqizo, inani lamadivayisi wesignali yethrafikhi liyethulwa.
Izimfuneko zenombolo yamadivayisi esignali yethrafikhi
1. Uma ibanga eliphakathi kolayini wokupaka ongenisiwe kanye nesiginali yethrafikhi ephambene lingaphezu kwamamitha angama-50, okungenani iqembu elilodwa lizokwengezwa emnyango; lapho ibanga eliphakathi kolayini wokupaka ongenisiwe kanye nohlamvu oluphambene lingaphezu kwamamitha angu-70, iyunithi ekhipha ukukhanya ehambisanayo izokhethwa. Usayizi wendawo ekhanyayo ngu-φ400mm.
2. Idivayisi yesignali yethrafikhi inemizila eminingi ebonisiwe eqenjini lezimpawu zethrafikhi lapho uphuma khona. Uma umzila obonisiwe ungekho phakathi kwezinhla ezintathu ezilandelayo ukusuka kulayini wokupaka ukuya kulayini wokupaka, iqembu elilodwa noma ngaphezulu kufanele lengezwe ngokufanele.
