Umlando wezilawuli zesiginali yethrafikhi

Umlando weIsilawuli se-Traffic SignalIzinsuku ezi-S zibuyele emuva ekuqaleni kwekhulu lama-20 lapho kunesidingo esicacile sendlela ehlelekile futhi esebenza kahle yokuphatha ukugeleza kwezimoto. Njengoba inani lezimoto ezisendleleni liyanda, kanjalo nesidingo sezinhlelo ezingalawula ngempumelelo ukunyakaza kwezimoto ezindaweni zokuhlangana.

Abalawuli bokuqala abagibeli bezimoto kwakungamadivayisi alula wemishini asebenzisa uchungechunge lwamagiya nama-levers ukuphatha isikhathi sezimpawu zomgwaqo. Lezi zilawuli zokuqala zazisetshenziswa ngesandla yizikhulu zethrafikhi, ezizoshintsha isiginali kusuka kokubomvu kuya koluhlaza ngokususelwa ku-traffic flow. Ngenkathi lolu hlelo luyisinyathelo esiqonde ngqo, akunjalo ngaphandle kokushiyeka kwalo. Kokunye, kuncike kakhulu ekwahlulelweni kwezikhulu zethrafikhi, ongenza amaphutha noma athonywe yizinto zangaphandle. Ngaphezu kwalokho, uhlelo alukwazi ukuzivumelanisa nezinguquko ekuhambeni kwethrafikhi usuku lonke.

Ngo-1920, isilawuli sokuqala se-othomathikhi se-othomathikhi sakhiwa ngempumelelo e-United States. Le nguqulo yokuqala yasebenzisa uchungechunge lwezikhathi ze-elektromokheli zokulawula isikhathi sezimpawu zomgwaqo. Ngenkathi kuwukuthuthuka okukhulu ngohlelo lwezandla, kusakhawulelwe emandleni ayo okuzivumelanisa nezimo eziguqukayo. Kwakungenjalo kuze kube ngu-1950 ukuthi kwakhiwa abalawuli bokuqala abasebenza ngezimoto. Lezi zilawuli zisebenzisa izinzwa ukuthola ukuba khona kwezimoto ezindlini zokuhlangana futhi zilungise isikhathi sezimpawu zomgwaqo ngokufanele. Lokhu kwenza uhlelo luququde futhi luphendule futhi lungazivumelanisa kangcono nokushintshashintsha kwezimoto.

Ama-Microprocessorses-based traffic Signal Strations avele ngawo-1970s, ethuthukisa ukusebenza kohlelo. Lezi zilawuli ziyakwazi ukucubungula futhi zihlaziye idatha yokuhlangana ngesikhathi sangempela, okuvumela ukuphathwa kwethrafikhi okunembile futhi okusebenzayo. Ngaphezu kwalokho, bayakwazi ukuxhumana nabanye abalawuli kule ndawo ukuxhumanisa isikhathi sezimpawu zomgwaqo ephaseji.

Eminyakeni yamuva, ukuthuthuka kobuchwepheshe kuqhubekile nokuqhubeka nokucindezela amakhono ezilawuli zesiginali yethrafikhi. Ukuvela kwamadolobha ahlakaniphile kanye ne-Intanethi yezinto kukhulise ukuthuthukiswa kwabalawuli bezimpawu zethrafikhi ezikwazi ukuxhumana namanye amadivaysi ahlakaniphile nezinhlelo. Lokhu kuvula amathuba amasha okuthuthukisa ukuhamba kwethrafikhi kanye nokunciphisa ukugcwala, njengokusebenzisa idatha kusuka ezimotweni ezixhunyiwe ukwenza kahle isikhathi sesiginali.

Namuhla, abalawuli bezimpawu zethrafikhi bayingxenye ebalulekile yezinhlelo zesimanje zokulawulwa kwezimoto. Basiza ukugcina izimoto zihamba ngemigwaqo futhi zidlala indima ebalulekile ekuthuthukiseni ukuphepha, ukunciphisa ukugcwala, nokunciphisa ukungcoliswa komoya. Njengoba amadolobha ayaqhubeka nokukhula futhi abe yindawo ebeka emabayeni, ukubaluleka kwezilawuli zesiginali yethrafikhi ezisebenza kahle kuzoqhubeka nokukhula.

Ngamafuphi, umlando wezilawuli zesiginali yethrafikhi ungenye yezinto ezintsha nokwenza ngcono. Ukusuka kumadivayisi alula wemishini ekuqaleni kwekhulu lama-20 kuya kwanamuhla abalawuli abaxhumekile, ukuvela kwezilawuli zesiginali yethrafikhi kuqhutshwa isidingo sokuphathwa kwethrafikhi okuphephile nokusebenza kahle. Njengoba ubuchwepheshe buqhubeka buvela, silindele ukuthuthuka okwengeziwe kubalawuli bezimpawu zethrafikhi ezizosiza ekwakheni amadolobha ahlakaniphile, amemeze kakhulu ngokuzayo.

Uma unesifiso samalambu omgwaqo, wamukelekile ukuxhumana nomhlinzeki womhlinzeki wethrafikhi ye-Qixiang kuyeFunda kabanzi.
