Amaqhawe angaziwa aziwa ngokuthiabalawuli bezimpawu zethrafikhidlala indima ebalulekile ekuphatheni ukugeleza kwethrafikhi lapho kuhlangana khona. Cishe ubabone bafakwa ezigxotsheni ezinde noma ziboshwe emabhokisini amancane ohlangothini lomgwaqo, bebheke ukugcwala nokuxinana komgwaqo.
Yini isilawuli sesiginali yethrafikhi?
Kalula nje, isilawuli sesiginali yethrafikhi iyithuluzi le-elekthronikhi elixhumanisa amasiginali omgwaqo asezindaweni ezihlangene. Injongo yayo eyinhloko ukulawula ukuhamba kwezimoto nabahamba ngezinyawo ukuze kuqinisekiswe ithrafikhi ephephile nesebenzayo. Kusetshenziswa ama-algorithms ahlukahlukene kanye nezinhlelo zesikhathi, isilawuli sinquma ukuthi isinali ngalinye kufanele lishintshe nini ukuvumela izimoto ukuba zihambisane nendawo ngokulandelana okuhlelekile.
Inhloso yesilawuli se-traffic signal
Izilawuli zesiginali yethrafikhi zihlelelwe ukubheka izinto ezahlukahlukene lapho zinquma ukuthi ukukhanya ngakunye kufanele kuhlale kuluhlaza, i-amber, noma ibomvu. Lezi zinto zifaka ivolumu yethrafikhi ephaketheni ngalinye, amaphethini wesikhathi lapho ehlangene khona, ubukhona babahamba ngezinyawo, kanye nesikhathi sosuku noma isonto. Ngokuhlaziya ngokuqhubekayo nokushintsha lezi zinto, isilawuli sihlose ukunciphisa ukugcwala kwethrafikhi, sinciphise ukubambezeleka futhi sithuthukise ukuphepha kubo bonke abasebenzisi bomgwaqo.
Imisebenzi yesilawuli se-Traffic Signal
Eminye yemisebenzi esemqoka yesilawuli sesiginali yethrafikhi yikhono lokuthola ubukhona bezimoto nabahamba ngezinyawo abalindile ekuxhumaneni. Isebenzisa izinzwa ezinhlobonhlobo, njengokuthola izindandatho ezingcwatshwe ngaphansi kwemigwaqo noma amakhamera afakwe ezigxotsheni, ukuqoqa lolu lwazi. Ngokuzwa ngokunembe ubukhona nokunyakaza kwezimoto nabahamba ngezinyawo, isilawuli singaguqula uhlelo lwaso lwesikhathi ukuze sikwazi ukuzivumelanisa nezimo eziguqukayo.
Ngaphezu kokuphatha ukugeleza kwethrafikhi, abalawuli bezimpawu zethrafikhi nabo badlala indima ebalulekile ezimweni eziphuthumayo. Zingahlelwa ukuthi zibeke phambili izimoto eziphuthumayo ngokunwebeka ngokuzenzakalela amalambu aluhlaza noma amasiginali wokukhohlisa ukusula indlela. Lokhu kuqinisekisa ukuthi abaphenduli bezimo eziphuthumayo bangadabula ngokushesha nangokuphepha ukuhlangana, behlisa isikhathi sokuphendula futhi basindise izimpilo ezinamandla.
Ngokwengeziwe, abalawuli besiginali bendawo banamuhla bavame ukufakwa ngezici ezithuthukile ukwandisa ukusebenza kahle futhi banciphise ukusetshenziswa kwamandla. Abanye abalawuli bayakwazi ukuxhumana nabanye ngoxhumano olungenantambo, okubavumela ukuba baxhumane nesikhathi sesiginali ngesikhathi sokuhlangana okuseduze. Lokhu akugcini nje ngokuthuthukisa ukugeleza kwethrafikhi okuphelele kepha kunciphisa ukusetshenziswa kukaphethiloli kanye nokukhishwa ngokuncipha ukuma okungadingekile futhi kuqala.
Ekuphetheni, abalawuli bezimpawu zethrafikhi bayingxenye ebalulekile yengqalasizinda yethu yasemadolobheni. Lawa madivaysi anikela ekuhambeni okubushelelezi nokuphephile kwethrafikhi ngokuhlaziya ngokucophelela amaphethini omgwaqo, ukuthola ubukhona bezimoto nabahamba ngezinyawo, kanye nokuguqula isikhathi esifanele. Indima yabo ekuphatheni izimo eziphuthumayo kanye nokunciphisa ukusetshenziswa kwamandla akunakugcizelelwa. Ngakho-ke ngokuzayo lapho ubona isilawuli sesignali sethrafikhi sathola phezulu ngaphezulu komgwaqo, khumbula umsebenzi obalulekile owenzayo ekugcineni umgwaqo usebenza kahle.
Uma unentshisekelo kulawuli lwesiginali yethrafikhi, wamukelekile ukuxhumana nomkhiqizi wesilawuli se-qxiangFunda kabanzi.
