Njengoba imoto iguqule impilo yasemadolobheni, isidingo sokulawulwa kwezimoto okuhlelekile saba yinto ebalulekile ukuvikela izimpilo nokugcina ukuhamba kahle. Imigwaqo yokuqala, eyayihanjwa abahamba ngezinyawo, izimoto ezihanjiswa amahhashi, nezimoto ezintsha ezivela, yayibhekana nezingxabano eziningi ezagqamisa ukubaluleka kwezimpawu ezijwayelekile. Ohulumeni besimanje namabhizinisi aqaphela ukuthi uhlelo oluhambisanayo lwezimpawu zezimoto ngeke nje lunciphise izingozi kodwa futhi luzovumela ukuhamba okukhulu emigwaqweni enabantu abaningi. Ezinkampanini ezibandakanyeka kwezokuthutha ezihlakaniphile, njengeShandong Penghui Intelligent Technology Co., Ltd., lesi sikhathi sadala isidingo samadivayisi athembekile okulawula izimoto, kusukela ezibani ezilula zezimoto kuya kubalawuli bezimpawu ezithuthukisiwe. Ukuqonda ukuthi kungani izimpawu zezimoto zisebenzisa imibala ebomvu, ephuzi, neluhlaza, nokuthi lezo zinketho zaba yinto ejwayelekile nini, kusiza abahleli nabakhiqizi ukuthi bakhethe izimpambano ezivikelekile nezindawo zabahamba ngezinyawo njengokufakwa kwezimpawu zezebra crossing.

Izibani zokuqala zethrafikhi zanamuhla zavela ngawo-1860s eLondon lapho kwafakwa izibani zesiginali ezikhanyiswa ugesi ukuze zilawule ukuhamba kwezinqola ezihanjiswa ngamahhashi eduze kwePalace of Westminster. Lezi zibani zesiginali zokuqala zazisebenzisa ingilazi enemibala ukukhombisa ukuthi kuyiwe noma kuyiwe, futhi zazisebenza ngesandla ngamaphoyisa. Yize izibani zokuqala zathuthukisa ukuphepha ezindaweni ezimbalwa ezibalulekile, ukukhanyisa okulinganiselwe, ukusebenza ngesandla, kanye nokuba sengozini sezulu nezingozi kwakuvimbela ukusetshenziswa kabanzi. Njengoba amadolobha ayechitha futhi ubunikazi bezimoto bukhula ekuqaleni kwekhulu lama-20, onjiniyela nabasemagunyeni bakamasipala babuyekeza ukwakhiwa kwezibani, befuna izixazululo ezisebenzisa ugesi. Ukuguquka kusuka ezibani zesiginali kuya ezibani zethrafikhi ezilawulwa ugesi kubonisa isigaba esikhulu emlandweni wokuphathwa kwethrafikhi futhi kwavula indlela yezinto ezintsha ezifana nesikhathi sokubala kanye nezibani zezwi ukuze kuphephe abahamba ngezinyawo.

Ngeminyaka yama-1910 nawo-1920, abasunguli bahlola izimpawu zikagesi ezizenzakalelayo ukufaka izibani ezazilawulwa ngesandla; phakathi kwabo, uLester Wire uyiswa umsebenzi wokuqala ezibazini zethrafikhi zikagesi. UWire, umphoyisa owayekhathazekile ngokuphepha kwezimpambano zemigwaqo, wadala enye yezibani zokuqala zethrafikhi ezisebenzayo ezazisebenzisa izikrini zemibala ukudlulisa imiyalelo elula kubashayeli. Ngemuva kwezinto azisungulayo, abanye abasunguli nezinkampani bathuthukisa izindlela zokulawula isikhathi, izibani, nezindawo zezimpawu ukuze izimpambano zemigwaqo zikwazi ukulawulwa ngendlela ehlelekile kunokuba kube ngokungahleliwe. Lesi sikhathi sabona futhi ukwethulwa kwezimpawu eziningi—okubomvu ukuma, okuluhlaza ukuya, nokubomvu ukuba qaphela—kunikeza uhlelo lwezinyathelo ezintathu olwathuthukisa ukuphepha futhi lwehlisa ukudideka kubashayeli nabahamba ngezinyawo. Lezi zintuthuko zabeka isisekelo salokho esikubiza manje uhlelo lwezibani zethrafikhi futhi kwathinta abakhiqizi abanjengoShandong Penghui Intelligent Technology Co., Ltd. ukuthi bathuthukise imigqa yemikhiqizo ehlanganisa izibani zethrafikhi ze-LED eziqinile kanye nabalawuli besimanje.

Ngaphambi kwezinhlelo zikagesimende, izibani zezimpawu zazimelela isimo sobuciko ekuvikelekeni komgwaqo ngokusebenzisa ukukhanya okumibalabala ukuqondisa ukunyakaza ezindaweni ezibalulekile. Abasebenzi babeshintsha izikrini zezibani noma ukubonisa ukuze balawule ukuhamba, indlela eyayisebenza ezimeni ezincane kodwa yahluleka ngenxa yokwanda kobunzima bethrafikhi yemoto. Idizayini nokukhethwa kwemibala yalezi zibani kwathonywa yizimpawu zasolwandle nama-semaphore esitimela, okwakudingeka adlulise imiyalo ecacile, engadukisi ngaphezu kwamabanga nezimo eziguquguqukayo. Njengoba amanethiwekhi emigwaqo ayanda, amadolobha ayezama izimpawu ezilawulwa amaphoyisa, ama-semaphore esandla, namashejuli esikhathi kuze kube izixazululo zikagesimende ezizenzakalelayo zaba ngcono ekuqinisekiseni njalo ukuhleleka kwethrafikhi. Ukushintsha kusuka ezibani kuya ezibani zethrafikhi ezizenzakalelayo kwadala namathuba amasha okuthuthukiswa kwezimboni, kuvumela izinkampani ukuthi zihlanganise izici ezifana nezinkinobho zokucindezela zabahamba ngezinyawo, ukuvumelanisa izimpawu zezinqamuleli zezebra, nemisindo yezindlebe kubasebenzisi abangaboni kahle.

Ikhulu lama-20 leminyaka lazalela izimpawu eziningana ezichazayo zokulawulwa kwethrafikhi yesimanje, okubandakanya ukwenziwa okujwayelekile kwezincazelo zemibala—okubomvu ukuma, okuluhlaza ukuya, nokuphuzi (noma i-amber) ukuze kuxwayiswe—nokuthuthukiswa kwezinhlelo zesiginali ezihlangene ukuze kuthuthukiswe ukuhamba kwezimoto emigwaqweni emikhulu. Onjiniyela bethrafikhi bengenise amasu esikhathi njengokuthi isikhathi esinqunyiwe, ukulawulwa okusebenzayo, nokulawulwa kwesiginali okuzivumelanisa nezimo, ngalinye linikeza ukusabela okuthuthukisiwe esidingweni sethrafikhi. Ukuqhubeka kobuchwepheshe, ikakhulukazi ukusuka ezibani ze-incandescent kuya kuma-LED, kwandise ukubonakala, kunciphise ukusetshenziswa kwamandla, futhi kwandisa impilo yesevisi yezibani zethrafikhi. Ngaphezu kwalokho, ukuhlanganiswa nobuchwepheshe bokuthola—imishayo ye-inductive, ukutholwa kwevidiyo, ne-radar—kwavumela iziginali ukuthi ziphendule kumavolumu esikhathi sangempela, kuthuthukisa ukuphepha ezingxenyeni zomgwaqo nasezindaweni zokudlula abahamba ngezinyawo. Abakhiqizi, okubandakanya iShandong Penghui Intelligent Technology Co., Ltd., bayingxenye yalo mlando, behlinzeka ngemikhiqizo yezibani zethrafikhi ehlangabezana namazinga esimanje wokuqina, ukubonakala, nokuhambisana nesilawuli.

Uhlelo lwemibala emithathu—obomvu, ophuzi, oluhlaza—luhlanganisa isiko lomlando, ukuqonda komuntu, kanye nokucaca okusebenzayo. Okubomvu kudala kukhombise ingozi noma ukuvinjelwa ezindaweni eziningi zamasiko futhi kulula ukubona kude, okwenza kube ngempumelelo ukuyala abashayeli ukuthi bayeke. Okuluhlaza kukhombisa imvume yokuqhubeka futhi kuhlukile kokubomvu ngobude bamagagasi nokukhanya okubonwayo, kunciphisa ubungozi bokudideka. Ophuzi (obomvu obukhanyayo) usebenza njengesixwayiso esidlulayo esilungiselela abasebenzisi bomgwaqo ushintsho oluzayo kusuka ekuhambeni ukuya ekumeni, kunciphisa ukubhonqisa ngokungazelelwe nokushayisana kwangemuva. Lezi zinketho zemibala zamukelwa kabanzi ngokuhlanganiswa kwesivumelwano samalungiselelo, izivumelwano zamazwe omhlaba, kanye nesipiliyoni esisebenzayo emashumini eminyaka wokusebenza kwezimoto. Ngasekupheleni kwawo-1900, izindawo eziningi zazizinzile ohlelweni lwemibala emithathu olusasetshenziswa namuhla, ngokuthuthukiswa okuncane njengokubekwa okujwayelekile (ngokuvundlile noma ngokuvundlile), usayizi wesignali, kanye nemininingwane yokukhanya.

Eminyakeni yamuva nje, izinto ezintsha ezithuthukisiwe ezihlobene nezimpawu zomgwaqo zigxile kulwazi lomsebenzisi, ukufinyeleleka, nokusebenza kahle. Izibali zesikhathi eziboniswa ezikrinini zabahamba ngezinyawo zitshela abasebenzisi ukuthi kusasele isikhathi esingakanani ukuze bawele, kunciphisa ukungabaza kanye nokuqala okungaphephile maphakathi nomgwaqo. Izimpawu zezwi zinikeza izimpawu ezikhulunyiwe noma ezilalelwayo zabahamba ngezinyawo abangaboni kahle, zihlanganiswe nezinkinobho zokucindezela ezithinta umzimba ukuthuthukisa ukufinyeleleka okubandakanya bonke. Izibali zesikhathi ezibhekise ezimotweni kanye nesikhathi esiguquguqukayo samagaba kuthuthukisa ukudlula ngenkathi kunciphisa ukubambezeleka okungadingekile, futhi umqondo wesibonakaliso sesandla sokushayela noma isenzo somzimba ezimweni ezithile zokulawula izimpawu zomgwaqo zesikhashana uhambisana nezinhlelo ezizenzakalelayo lapho isiqondiso somuntu sisadingeka khona. Iziyalezo zedolobha elihlakaniphile zihlanganisa izibani zomgwaqo nezinhlelo zokuphatha ezimaphakathi, ezivumela ukubeka phambili okunamandla kwezokuthutha zomphakathi, izimoto eziphuthumayo, nabahamba ngebhayisikili. Lezi zici zibonakala emakhalogini emikhiqizo yabaphakeli ababheka phambili; isibonelo, ikhasi lemikhiqizo ye-Shandong Penghui Intelligent Technology Co., Ltd. libonisa izinhlobonhlobo zezibani zomgwaqo ze-LED, amamojuli abahamba ngezinyawo, kanye nezilawuli ezikhethekile eziklanyelwe izidingo zesimanje zezimpambaniso.

Ukwenziwa kwezimpawu zomgwaqo wezinyathelo zezebra kuyahlukahluka kuye ngendawo, kodwa ngokuvamile kuhlanganisa imigqa ebonakala kakhulu nezilawuli ezinemishini ukuvikela abahamba ngezinyawo. Izimpawu ezinikezelwe ezindaweni zokuwela ngokuvamile zihlanganisa izikrini zabahamba ngezinyawo, izinkinobho zokucela, izikrini zokubala phansi, futhi ngezinye izikhathi izindawo eziyisicaba ezithintekayo ukuze ziqondise abasebenzisi abangaboni kahle. Ukuhlanganisa izibani zethrafikhi zezimoto nezimpawu zomgwaqo wezinyathelo zezebra kusiza ukwabela isikhathi sokudlula ngokuphepha ngenkathi kugcinwa ukuhamba kwezimoto lapho isidingo sabahamba ngezinyawo singekho phezulu. Ukufakwa kwezinto zokuthola—njengezinzwa ezikhombisa ukuba khona komuntu ohamba ngezinyawo noma izinkinobho zokucela ezisebenza ngokufunwa—kuqinisekisa ukuthi ukuwela kuyaphendula, kunciphisa ukulinda okungadingekile futhi kuthuthukise ukuthobela. Abahlinzeki njengeShandong Penghui Intelligent Technology Co., Ltd. banikela ngezixazululo ezihlanganisiwe ezihlanganisa izibani zethrafikhi zezimoto, amamojuli ezimpawu zomgwaqo wezinyathelo zezebra, kanye ne-logic yesilawuli ukuze kuhlangatshezwane namazinga kamasipala futhi kuthuthukiswe ukuphepha kwezindawo zokuhlangana.

Uhlelo lwesimanje lwezibani zethrafikhi ezintathu-imibala lwaqala ukwamukelwa kabanzi maphakathi nekhulu lama-20 leminyaka, yize izikhathi zokwamukelwa zazihlukahlukene emazweni omhlaba. E-United States nasezindaweni eziningi zaseYurophu, isikhathi sangemva kweMpi Yezwe II sabona imizamo ehlangene yokwenza imininingwane yemibala, imiklamo yezibani, kanye nezinqubo zokubeka zibe semthethweni. Izivumelwano zamazwe omhlaba kanye nemizimba yobunjiniyela bezithuthuthu kazwelonke kwakufakwe ukukhanya, imininingwane yemibala, kanye nezinqubo zokusebenza, okuvumela abakhiqizi ukuthi bakhiqize imishini ehambisanayo. Ngeminyaka yama-1960 nama-1970, ubuchwepheshe be-LED baqala ukubonakala ezindaweni ezithile kodwa kamuva kuphela baba khona yonke indawo njengoba ama-LED athuthuka ekukhanyeni nasekuthembekeni. Isimo samanje esizinzile—obomvu, ophuzi, oluhlaza ngezikhathi ezijwayelekile, izikrini zabahamba ngezinyawo, kanye nezici zokufinyeleleka ongazikhetha—kubonisa amashumi eminyaka entuthuko eqhubekayo kanye nokuqiniswa kwemithetho, okuholela ezibani ezithembekile abashayeli nabahamba ngezinyawo abazibona emhlabeni wonke.

Kubaphathi bokuthenga, abahleli bezokuthutha, kanye namabhizinisi afuna ukutshala imali ekuphathweni kwemigwaqo, kunezinto ezithile ezibalulekile okufanele zicatshangelwe: ukusebenza kahle kwamandla (i-LED vs. i-incandescent), ukuhlela (ukulula kokugcina nokushintsha), ukuhambisana nezilawuli ezikhona, kanye nokwesekwa kwezici ezifana nezinsuku zokubala noma izimpawu zomsindo. Ukuhlaziywa kwezindleko zokuphila kuvame ukuhlinzeka ngenzuzo kumalambu emigwaqo e-LED ngenxa yezindleko eziphansi zokusebenza kanye nezikhathi zokusebenza ezinde naphezu kwezindleko eziphezulu zokuthenga zokuqala. Amandla okuhlanganisa—njengokwesekwa kwezinhlelo zokulawula izimpawu ezizenzakalelayo kanye nokubhekwa kude—avumela izifunda ukuthi zandise amaphrojekthi ezokuthutha ezihlakaniphile futhi zinciphise isikhathi sokungasebenzi. Izinkampani ezifana neShandong Penghui Intelligent Technology Co., Ltd. zikhomba ukuzihlanganisa nalezi zidingo ngokuhlinzeka ngohlobo lwezimpahla zamalambu emigwaqo nezixazululo zokulawula; imininingwane eyengeziwe mayelana namakhono abo ingatholakala kumakhasi eKhaya nakuMayelana Nathi ukuze kusize abathengi bahlola ukuhambisana nezinsizakalo.

Izimpawu zomgwaqo ziye zavela kusukela ezibani zangenkulungwane yeshumi nesishiyagalolunye kuya kumadivayisi ahlakaniphile, axhunyiwe, adlala indima enkulu ekuphepheni komgwaqo nasekuphathweni kokuhamba. Isivumelwano sezimibala ezintathu—obomvu, ophuzi, oluhlaza—siye sabonakala sinamandla ngoba sihlanganisa incazelo ecacile nezinzuzo zokusebenza ezivunyiwe, futhi uhlelo lwaba nokuqina okubanzi maphakathi nenkulungwane yama-20 ngemizamo yokwenza okufanayo. Ukuqhubeka kwezinto ezintsha, okuhlanganisa izibali-sikhathi ezibala phansi, izimpawu zezwi, nokulawula okuguquguqukayo, kugcina isibonakaliso somgwaqo sinomthelela njengoba amadolobha efuna imigwaqo ephephile, esebenza kahle kakhulu. Ezinhlanganweni ezibandakanyeka ekwakhiweni nasekusetshenzisweni kwemikhiqizo yezokuthutha ehlakaniphile, njengeShandong Penghui Intelligent Technology Co., Ltd., kusekhona amathuba okuthuthukisa ukuphepha kwezindawo ezihlangana ngazo imigwaqo ngokusebenzisa ihadiwe ethuthukisiwe, izici ezitholakala kalula njengama-module ezimpawu zokudlula komgwaqo, nokuhlanganiswa namasu okuphatha imigwaqo yedolobha. Ngokuqonda umlando, isizathu sobuchwepheshe, namakhono esimanje ezibani nezimpawu zomgwaqo, abenzi bezinqumo kamasipala namabhizinisi bangenza izinqumo ezinolwazi ezithuthukisa ukuphepha nokuhamba kubo bonke abasebenzisi bomgwaqo.

Ukufunda okwengeziwe kanye nezicelo zokuthenga zingaqala kumalisti wemikhiqizo yenkampani namakhasi ezinkampani: vakashela ikhasi leMikhiqizo ukuze uhlole amamodeli amaTraffic Light atholakalayo nezincazelo, bheka ikhasi leKhaya ukuze uthole isithombe esijulile sokugxila kwabo kwezokuthutha okuhlakaniphile, noma uxhumane neKhasi leSithombe Nathi ukuze uthole umlando wenkampani nemininingwane yokuxhumana.
