Izibane zendlela ziluhlu lweemveliso zokhuseleko lwendlela. Zisisixhobo esibalulekileyo sokuqinisa ulawulo lwendlela, ukunciphisa iingozi zendlela, ukuphucula ukusebenza kakuhle kwendlela, kunye nokuphucula iimeko zendlela. Zisebenza kwiindawo ezinqamlezileyo ezifana ne-cross kunye ne-T-shape, zilawulwa ngumatshini wokulawula isignali yendlela ukukhokela izithuthi kunye nabahambi ngeenyawo ukuba badlule ngokukhuselekileyo nangokucwangcisiweyo.
1, isignali yokukhanya okuluhlaza
Isignali yesibane esiluhlaza sisignali yendlela evumelekileyo. Xa isibane esiluhlaza sivuliwe, izithuthi kunye nabahambi ngeenyawo bavumelekile ukuba badlule, kodwa izithuthi ezijikayo azivumelekanga ukuba zithintele ukudlula kwezithuthi ezihamba ngqo kunye nabahambi ngeenyawo.
2, isignali yesibane esibomvu
Isibane esibomvu sisibane sokudlula esingavumelekanga kwaphela. Xa isibane esibomvu sivuliwe, akuvumelekanga ukuhamba ngemoto. Isithuthi esijika ngasekunene singadlula ngaphandle kokuthintela indlela yezithuthi nabahambi ngeenyawo.
Isibonakaliso sesibane esibomvu sisiboniso esingavumelekanga esinentsingiselo enyanzelekileyo. Xa isiboniso siphuliwe, isithuthi esingavumelekanga kufuneka sime ngaphandle komgca wokuma. Abahambi ngeenyawo abangavumelekanga kufuneka balinde ukukhululwa endleleni; isithuthi asivumelekanga ukucima xa silinde ukukhululwa. Akuvumelekanga ukuqhuba ucango. Abaqhubi bezithuthi ezahlukeneyo abavumelekanga ukuphuma kwisithuthi; ukujika ngasekhohlo kwebhayisekile akuvumelekanga ukudlula ngaphandle kwesiphambano, kwaye akuvumelekanga ukusebenzisa indlela yokujika ngasekunene ukudlula.
3, isignali yokukhanya okutyheli
Xa isibane esimthubi sivuliwe, imoto enqumle umgca wokuma ingaqhubeka idlula.
Intsingiselo yesibane esimthubi iphakathi kwesibane esiluhlaza kunye nesibane esibomvu, zombini icala elingavumelekanga ukuba lidlule kunye necala elivunyelwe ukuba lidlule. Xa isibane esimthubi sivuliwe, kuyalumkiswa ukuba ixesha lokudlula lomqhubi kunye nomhambi ngeenyawo liphelile. Kungekudala liza kuguqulwa libe sisibane esibomvu. Imoto kufuneka ipakwe emva komgca wokuma kwaye abahambi ngeenyawo akufuneki bangene kwindawo yokunqumla. Nangona kunjalo, ukuba imoto iwela umgca wokuma kuba ikufutshane kakhulu nomgama wokupaka, inokuqhubeka idlule. Abahambi ngeenyawo abasele bekwindawo yokunqumla kufuneka bajonge imoto, okanye bayidlule ngokukhawuleza, okanye bahlale kwindawo okanye babuyele kwindawo yokuqala.
