Izibani zomgwaqo zilawulwa kanjani? Impendulo itholakala ku-abalawuli bezimpawu zethrafikhi, okuyizinto ezibalulekile ekuphatheni ukuhamba kwezimoto ezindaweni zokuhlangana kwemigwaqo. Kulesi sihloko, sizohlola indima yabalawuli bezimpawu zomgwaqo nokuthi basebenza kanjani ukuqinisekisa ukuthi izimoto zihamba kahle futhi ngendlela efanele emgwaqweni.
Iyini isilawuli sesignali yethrafikhi?
Abalawuli bezimpawu zomgwaqo bangamadivayisi ekhompyutha alawula izibani zomgwaqo ezindaweni zokuhlangana. Umsebenzi wawo oyinhloko ukunikeza ilungelo lendlela ezinyakazweni ezahlukene zezimoto ngokunquma ukuthi iqembu ngalinye lezimoto kufanele libe nini nokukhanya okuluhlaza. Laba balawuli bavame ukufakwa kumakhabhinethi eduze kwezindawo zokuhlangana.
Isilawuli sisebenza ngokusekelwe kusethi yama-algorithms achazwe ngaphambilini acabangela izici ezahlukahlukene njengomthamo wethrafikhi, isikhathi sosuku, kanye nomsebenzi wabahamba ngezinyawo. Asiza ukuthuthukisa ukuhamba kwethrafikhi iyonke futhi anciphise ukuminyana. I-algorithm isebenzisa okokufaka okuvela kuma-sensor ahlukahlukene, ama-detector, kanye nama-timer ukuze kubalwe indlela ephumelela kakhulu yokwabela izikhathi eziluhlaza ukuhamba kwethrafikhi okuhlukene.
Yini equkethwe yisilawuli sesignali yethrafikhi?
Inzwa evamile esetshenziswa kubalawuli bezimpawu zomgwaqo yinzwa yokuthola izimoto. Lezi zinzwa zivame ukufakwa ezindleleni zokuhamba ngezinyawo futhi zingathola ukuthi kukhona izimoto ezilinde ezimpambanweni zemigwaqo. Lapho imoto ifika ekukhanyeni okubomvu, inzwa ithumela isignali kumlawuli, ozobe esenquma isikhathi esifanele sokushintsha ukukhanya kube luhlaza.
Izitholi zabahamba ngezinyawo ziyingxenye ebalulekile yabalawuli bezimpawu zomgwaqo. Lezi zitholi zivame ukubekwa eduze kwezindawo zokuwela zabahamba ngezinyawo futhi zingathola ukuthi kukhona yini abahamba ngezinyawo abalinde ukuwela umgwaqo. Uma kutholakala umuntu ohamba ngezinyawo, umlawuli uzonikeza isikhathi esiluhlaza isikhathi eside endaweni yokuwela ukuze aqinisekise ukuphepha kwabahamba ngezinyawo.
Ngaphezu kokufakwa kwezinzwa, abalawuli bezimpawu zethrafikhi basebenzisa ama-timer ukulawula ukuhamba kwethrafikhi. Ama-timer ngokuvamile ahlelwe ukuthi ahlele amaphethini ethrafikhi usuku lonke. Isibonelo, ngesikhathi sokujaha, ama-timer angasethwa ukuthi anikeze isikhathi esengeziwe sokukhanya okuluhlaza emigwaqweni emikhulu ukuze avumelane nenani elikhulu lethrafikhi.
Abalawuli bezimpawu zethrafikhi banamuhla bavame ukuxhunywa ezinhlelweni zokuphathwa kwethrafikhi ezihlanganisiwe. Uhlelo luvumela onjiniyela bethrafikhi ukuthi baqaphe futhi balawule ukuhlukana kwemigwaqo eminingi bekude. Ngokuhlaziya idatha yethrafikhi yesikhathi sangempela nokulungisa isikhathi sesignali ngokufanele, onjiniyela bangenza ngcono ukuhamba kwethrafikhi kuwo wonke amanethiwekhi omgwaqo.
Ngamafuphi, abalawuli bezimpawu zomgwaqo badlala indima ebalulekile ekuphatheni izibani zomgwaqo nokuqinisekisa ukuhamba kahle kwezimoto. Ngokusebenzisa okufakwayo okuvela kuma-sensor, ama-detector, kanye nama-timer, la madivayisi abela izikhathi zokukhanya okuluhlaza ekugelezeni kwezimoto okuhlukene ngokwe-algorithms echazwe ngaphambilini. Njengoba ubuchwepheshe buthuthuka, abalawuli bezimpawu zomgwaqo baba yinkimbinkimbi futhi bahlanganiswa nezinhlelo zokuphatha izimoto ezihlanganisiwe, ekugcineni okuholela emigwaqweni ephephile nesebenza kahle kubo bonke.
Uma unesifiso sokulawula isignali yethrafikhi, wamukelekile ukuxhumana nomkhiqizi wesilawuli sesignali yethrafikhi uQixiang kuFunda kabanzi.
