“Amagufwa y'imbwa” azenguruka? Izina ryamatsiko rituruka kumiterere yaryo, iyo urebye hejuru, ifata imiterere ya… “igufwa ryimbwa”, nkuko tumenyereye kubona mubikarito cyangwa ibikinisho. Na none, bitewe nimiterere yabyo, barashobora kwitwa kabiri "igitonyanga cyamazi".
Mubyukuri "igufwa ryimbwa" rotunda ituruka kumahuriro ya rotundas ebyiri itigera igera kumuzingi wuzuye, byombi bigahuzwa nuburyo bubiri, nibyiza gutandukana kumubiri, bikora nka rotunda imwe, ariko nkaho byari byacitsemo kabiri.
Ni igisubizo kigaragaza ko gifite akamaro haba mukongera umuvuduko wimodoka no kugabanya kugongana hagati yimodoka. Reba uko ikora muri iki gishushanyo:
Mugihe cyambere, imwe ifite urujya n'uruza rwinshi, irinda gukoresha amatara yumuhanda kugirango igenzure ibinyabiziga, igira uruhare mukugabanya umuvuduko wibinyabiziga no gutandukanya neza ibinyabiziga bihurira hagati yumuhanda. Niba ari ngombwa guhindura icyerekezo cyurugendo, abashoferi bategekwa guhora bajya kumurongo wa kabiri.
Mugihe cya kabiri, kugabanuka kugongana hagati yimodoka, biterwa cyane cyane no gutandukanya ibinyabiziga, bikarinda kugongana imbere (guhuza hagati yinzira zombi) no kwirinda kwiyongera kugongana kuruhande (ibinyabiziga bigonga imitwe kuri ruhande rw'ikindi kinyabiziga),
Nibyo byabonye umujyi wa Carmel, muri leta ya Indiana muri Amerika (ako kanya mumajyaruguru ya Indianapolis), usanzwe uzwiho umubare (hari 138 kandi ntuzahagarara hano) hamwe nuburyo butandukanye bwo kuzenguruka.
Carmel imaze kugira “amagufwa yimbwa” menshi azenguruka - nkiyiri muri videwo yerekanwe - yafashe umwanya wubundi bwoko bw’amasangano, munsi yumuhanda munini wumujyi unyura kandi ukabigabanyamo kabiri.
IIHS (Ikigo cy'Ubwishingizi ku mutekano wo mu muhanda cyangwa Ikigo cy'Ubwishingizi ku mutekano wo mu muhanda) cyakoze ubushakashatsi bugereranya umubare w'impanuka mbere na nyuma yo kubaka umuhanda wa “imbwa y'imbwa” (hamwe n'imyaka ibiri y'impanuka mbere yo kubaka) muri Carmel. Ibisubizo biramurikira: 63% munsi yumubare wimpanuka zose hamwe na 84% munsi yimvune zirimo ibikomere.
Kuzenguruka “imbwa igufwa” ntabwo iboneka muri Amerika gusa, ahubwo bigaragara ko aricyo gihugu cyakira vuba. Bashobora kandi gukoreshwa mubindi bice, usibye gukora nk'isangano ryinjira / risohoka ry'umuhanda, nkuko bigaragara kuri videwo ikurikira:
