Imbali yeisilawuli sesignali yethrafikhiIqala ekuqaleni kwenkulungwane yama-20 xa kwakukho imfuneko ecacileyo yendlela ehlelekileyo nefanelekileyo yokulawula ukuhamba kwezithuthi. Njengoko inani lezithuthi ezindleleni lisanda, imfuneko yeenkqubo ezinokulawula ngokufanelekileyo ukuhamba kwezithuthi kwiindawo ezidibana kuzo iindlela iyanda.
Abalawuli bokuqala beempawu zendlela yayizizixhobo ezilula zoomatshini ezazisebenzisa uthotho lweegiya kunye nee-levers ukulawula ixesha leempawu zendlela. Aba balawuli bokuqala babeqhutywa ngesandla ngamagosa eendlela, awayetshintsha isignali ukusuka kubomvu ukuya kuluhlaza ngokusekelwe ekuhambeni kweendlela. Nangona le nkqubo ikwicala elifanelekileyo, ayizizo ezingenazo iziphene zayo. Okokuqala, ixhomekeke kakhulu kwisigqibo samagosa eendlela, anokwenza iimpazamo okanye aphenjelelwe zizinto zangaphandle. Ukongeza, inkqubo ayikwazi ukuziqhelanisa notshintsho ekuhambeni kwezithuthi imini yonke.
Ngo-1920, umlawuli wokuqala wesignali yethrafikhi ozenzekelayo waphuhliswa ngempumelelo eMelika. Olu hlobo lokuqala lwalusebenzisa uthotho lwexesha le-electromechanical ukulawula ixesha lesignali yethrafikhi. Nangona luphuculo olukhulu kunenkqubo yesandla, lusalinganiselwe kubuchule balo bokuziqhelanisa neemeko zethrafikhi ezitshintshayo. Kwakungekho de kwaba ngeminyaka yoo-1950 apho abalawuli bokuqala besignali yethrafikhi abaguquguqukayo ngokwenene baphuhliswa khona. Aba balawuli basebenzisa ii-sensors ukubona ubukho bezithuthi kwiindawo zokudibana kwaye balungise ixesha lesignali yethrafikhi ngokufanelekileyo. Oku kwenza inkqubo ibe namandla ngakumbi kwaye iphendule kwaye inokuziqhelanisa ngcono nethrafikhi eguquguqukayo.
Abalawuli beempawu zethrafikhi abasebenzisa i-microprocessor bavele ngeminyaka yoo-1970, nto leyo eyaphucula ngakumbi ukusebenza kwenkqubo. Aba balawuli bayakwazi ukucubungula nokuhlalutya idatha ye-intersection ngexesha langempela, nto leyo evumela ulawulo oluchanekileyo nolusebenzayo lokuhamba kwethrafikhi. Ukongeza, bayakwazi ukunxibelelana nabanye abalawuli abakuloo ndawo ukuze balungelelanise ixesha leempawu zethrafikhi ecaleni kwendlela.
Kwiminyaka yakutshanje, inkqubela phambili kwezobuchwepheshe iqhubekile nokuphucula amandla abalawuli beempawu zendlela. Ukuvela kwezixeko ezikrelekrele kunye ne-Intanethi yezinto kukhuthaze uphuhliso lwabalawuli beempawu zendlela abanxibelelana nabanye abanokunxibelelana nezinye izixhobo kunye neenkqubo ezikrelekrele. Oku kuvula amathuba amatsha okuphucula ukuhamba kwezithuthi kunye nokunciphisa ukuxinana, njengokusebenzisa idatha evela kwizithuthi eziqhagamshelweyo ukuphucula ixesha lemiqondiso.
Namhlanje, abalawuli beempawu zendlela bayinxalenye ebalulekileyo yeenkqubo zolawulo lwendlela zanamhlanje. Banceda ukugcina izithuthi zihamba kwiindawo ezidibana kuzo kwaye badlala indima ebalulekileyo ekuphuculeni ukhuseleko, ukunciphisa ukuxinana, kunye nokunciphisa ungcoliseko lomoya. Njengoko izixeko ziqhubeka zikhula kwaye zisiba zizixeko, ukubaluleka kwabalawuli beempawu zendlela abasebenzayo kuya kuqhubeka kusanda.
Ngamafutshane, imbali yabalawuli beempawu zendlela iyinto entsha nephucukileyo rhoqo. Ukususela kwizixhobo ezilula zoomatshini ekuqaleni kwenkulungwane yama-20 ukuya kubalawuli abaphambili abadibeneyo banamhlanje, ukuguquka kwabalawuli bezimpawu zendlela kuye kwaqhutywa yimfuno yolawulo lwendlela olukhuselekileyo nolusebenzayo. Njengoko itekhnoloji iqhubeka nokukhula, silindele ukuqhubela phambili ngakumbi kubalawuli beempawu zendlela okuya kunceda ekudaleni izixeko ezikrelekrele nezizinzileyo kwixesha elizayo.
Ukuba unomdla kwizibane zendlela, wamkelekile ukuba unxibelelane nomthengisi wezibane zendlela uQixiang kuFunda ngokugqithisileyo.
