Ukuzungeza "ithambo lenja"? Igama elinelukuluku livela ekubunjweni kwalo okuthi, uma libhekwa phezulu, lithathe isimo sakudala se… “ithambo lenja”, njengoba sijwayele ukubona emakhathuni noma kumathoyizi. Futhi, ngenxa yokuma kwazo, zingabizwa ngokuthi i-double "drop drop water" nxazonke.
Ngokuyinhloko i-rotunda "yethambo lenja" iphumela ekuhlanganisweni kwama-rotunda amabili angakaze afinyelele indilinga ephelele, womabili ahlanganiswa ngezindlela ezimbili, okungcono kakhulu ahlukaniswe ngokomzimba, asebenza njenge-rotunda eyodwa, kodwa njengokungathi acindezelwe phakathi.
Kuyisixazululo esibonakala sisebenza kahle kakhulu ekwandiseni ukugcwala kwezimoto kanye nasekunciphiseni ukushayisana kwezimoto. Bona ukuthi kusebenza kanjani kulo mdwebo:
Esimweni sokuqala, lowo onokugeleza okukhulu kwethrafikhi, ugwema ukusetshenziswa kwamarobhothi ukuze alawule ukuhamba kwezimoto, unomthelela ekwehliseni isivinini sezimoto nasekuhlukaniseni okuphumelelayo kwethrafikhi ehlangana phakathi nendawo yempambanomgwaqo. Uma kudingekile ukuhlehlisa isiqondiso sokuhamba, abashayeli banesibopho sokuya njalo kumjikelezo wesibili.
Okwesibili, ukuncishiswa kokushayisana kwezimoto, kungenxa yalokhu kuhlukana kwezimoto, ukuvimbela ukushayisana kwangaphambili (lapho kuxhunywa khona amaroundabouts amabili) nokugwema ukwanda kokushayisana emaceleni (imoto eshayisa eceleni kwenye imoto. ),
Yilokho okutholwe idolobha laseKarmeli, esifundazweni sase-Indiana e-USA (ngokushesha enyakatho ye-Indianapolis), eselivele lalaziwa ngenombolo (sezikhona kakade eziyi-138 futhi ngeke zime lapha) kanye nezinhlobonhlobo zokujikeleza eseliwakhile.
IKarmeli isivele inezindawo ezimbalwa zokuzungeza “ithambo lenja” elisebenzayo - njengalena ekuvidiyo efakiwe - ethathe indawo yezinye izinhlobo zemigwaqo, ngaphansi nangaphezulu komgwaqo omkhulu wedolobha owunqamulayo futhi owuhlukanisa phakathi.
I-IIHS (Insurance Institute for Highway Safety noma i-Insurance Institute for Highway Safety) yenza ucwaningo oluqhathanisa nenani lezingozi ngaphambi nangemva kokwakhiwa kwemijikelezo “yethambo lenja” (enedatha yeminyaka emibili yengozi ngaphambi kokwakhiwa) eKarmeli. Imiphumela iyakhanyisa: ngo-63% ngaphansi kwenani eliphelele lezingozi kanye nama-84% ngaphansi enanini lokulimala okubandakanya ukulimala.
Imijikelezo “yethambo lenja” ayitholakali e-US kuphela, kodwa ibonakala iyizwe elishesha ukutholwa. Angasetshenziswa nakwezinye izimo, ngaphandle kokuthi asebenze njengempambanomgwaqo emnyango/ophumayo kuthelawayeka, njengoba kuboniswe kuvidiyo elandelayo:
