Kutheni kukho umahluko ocacileyo kwizibane zendlela ezidibanayo kwihlabathi liphela?

Izibane zendlela ezidibanayoKwiindawo ezidibanayo kudla ngokuba bomvu, tyheli, kwaye kuluhlaza, ngamanye amaxesha kukho utshintsho oluncinci. Ngasiphi isizathu? I-Qixiang Traffic, umenzi wenkqubo yesignali yendlela, uza kukunika umbono opheleleyo.

Ukususela ngeminyaka yoo-1830, izibane zendlela ezinqamlezileyo beziyinxalenye ebalulekileyo yobomi bethu bemihla ngemihla. Ngo-1920, izibane zendlela ezinqamlezileyo ezinemibala ebomvu, eluhlaza, netyheli zaziswa kwiindlela ezinkulu zaseDetroit. Iinkqubo zokubonisa uloliwe zazisebenza njengomzekelo wale nkqubo. Kwiminyaka eyalandelayo, izibane ezininzi zendlela ezinqamlezileyo zoyilo olufanayo zavela kwiindlela ezinkulu, kodwa imibala yazo yayingaguquguquki. Iindlela zaseMelika zaziqhutywa ngasese ngelo xesha, kwaye abaqhubi ngokuqinisekileyo babedidekile yimibala eyahlukeneyo yezibane zendlela ezinqamlezileyo ezazisetyenziswa kwiindawo ezahlukeneyo. Ukuze kuqinisekiswe ukufana kunye nokubekwa emgangathweni kwezibonakaliso zendlela, i-Federal Highway Administration yapapasha incwadi yesikhokelo yesixhobo sokulawula ithrafikhi esimiselweyo ngo-1935 eyayichaza ngokucacileyo ukuba izibane ezibomvu, eziluhlaza, nezityheli yayizizinto eziqhelekileyo.

Isizwe ngasinye kunye nommandla ngamnye unemithetho yawo malunga nokusetyenziswa ngokufanelekileyo kwezibane zendlela ezinqumlayo, nangona zikhona kuzo zonke izitalato. Umzekelo, xa abantu abahamba ngeenyawo benqumla isitalato, izibane zendlela ezinqumlayo kwilizwe lam zikhanya luhlaza, bomvu, tyheli, kwaye zikhanya tyheli, ngelixa eYurophu, ulandelelwano oluqhelekileyo luluhlaza, tyheli, tyheli, kwaye bomvu. Izibane eziluhlaza, tyheli, tyheli, tyheli, kwaye ezitshintshanayo zikhanya tyheli kunye bomvu zisetyenziswa eJamani naseCzech Republic. Ukongeza, ezinye izixeko, njengezibane zendlela ezaziwayo eBerlin, ziyila izibane zazo zendlela ezinqumlayo ukuze zifane nabantu abahambayo okanye abangenamaza.

1. Ukungalingani kweNkcubeko

Nangona ngokuqhelekileyo kuyamkelwa ukuba izibane eziluhlaza mazisetyenziswe xa kushukuma kwaye izibane ezibomvu mazisetyenziswe xa kumiswe, amanye amazwe anomahluko kwiinkcubeko xa kufikwa ekukhetheni imibala. Umzekelo, izibane zayo eziluhlaza zinokuba nombala oluhlaza okwesibhakabhaka ukuze zihambelane nemigaqo yolwimi kuba uluhlaza eJapan ludla ngokubizwa ngokuba yi-"cyan" (equka uluhlu lweblue-green ngesiJapan).

2. Icebo kunye noLawulo

a. Izinto Zembali Nezenkcubeko: Xa kucwangciswa, izixeko ezisakhasayo zisebenzisa iingcinga kunye nobuchwepheshe obuphezulu, zikhetha iintlobo ezintsha zezibane zendlela ezinqumlanayo; izixeko ezahlukeneyo zenza iintlobo ezahlukeneyo zezibane zendlela ezinqumlanayo ngokweempawu zazo ezahlukileyo.

b. Ifilosofi yoLawulo kunye neenjongo: Nangona ezinye izixeko zibeka phambili ukhuseleko lwendlela ngokwandisa amaxesha okuthintela kunye nokuphucula iinkqubo zokulumkisa, ezinye zibeka phambili ukusebenza kakuhle kwendlela ngokufaka izibane zendlela ezidibanayo ukuze kwandiswe isantya kunye nokuhamba kwezithuthi.

3. Inkqubela phambili ekuphunyezweni kweMigaqo-nkqubo

Kukho umahluko wemimandla kuyilo kunye nokusebenza kwezibane zendlela ezidibanayo kuba amasebe olawulo lwezithuthi asebenzisa imigaqo-nkqubo kwaye akhuthaza ubuchwepheshe obutsha ngamanani ahlukeneyo.

Umenzi wenkqubo yesignali yendlelaI-Qixiang Traffic yamkela abathengi abavela kwihlabathi liphela ukuba benze ngokwezifiso izibane zabo zendlela ezinqumlanayo! Ungayila kwaye utshintshe yonke into yemodeli, ukusuka kwindlela yokulawula ukuya kwizinto zomzimba wokukhanya kunye nemodyuli yokubonisa, nokuba yimodeli eyenzelwe wena kwiinxalenye ezithile zendlela, imodeli ethile yendlela, okanye imodeli eqhelekileyo yokunqumlanayo.
