Igishushanyo gisanzwe
Ivyitegererezo rusangi birabereye gukoreshwa mu mabarabara akomeye. Igabanywamwo uburyo buhagaze, uburyo buringaniye n’uburyo bwo mu buryo buhagaze n’uburinganire. Ico kigereranyo c’igihe kirekire kirabereye gutwara imodoka mu mabarabara asukuye kandi meza cane. Nk’akarorero, imodoka, amakamyo y’umuco n’ama minivas akenshi ahitamwo iyo nzira. Amapine apfutse n’umusaraba arabereye ku modoka ziringaniye canke ziremereye zifise ubushobozi bwo gukwegakwega cane ku mabarabara akomeye muri rusangi. Ipine rifise ibigereranyo bihagaze n’ivyo mu buryo buringaniye birafise ubushobozi bukomeye bwo kwimenyereza be n’ibikorwa vyinshi. Ntibibereye gusa ku mabarabara atandukanye gusa, ariko kandi ni meza ku modoka n’ibikamyo.
Igishushanyo c'inzira
Igishushanyo c’ibara ry’umusaraba na co nyene citwa ubuhinga bwa block, karangwa n’imirongo y’imirongo n’uburebure bw’ibarabara n’ahantu hatoyi cane (nk’ibice 40%~60%). Ivyitegererezo vy’ibihugu bigabanywamwo ubwoko bubiri: uburyo butarongowe kandi burongowe. Ivyitegererezo vy’ugutandukana ni vyo bija iyo vyakoreshejwe. Amapine yo mu nzira yo mu nzira arabereye gukoreshwa mu mabarabara y’amabuye, amabarabara y’ubutaka yoroshe n’ibibanza bitagira inzira. Kubera umuvuduko munini wo gukorana n’amabuye y’agaciro be n’ugushobora gutera imbere kw’amabuye, ntibibereye gutwara imodoka igihe kirekire mu mabarabara meza cane. Ahandi ho, ugushaza kw’amapine kuzogumaho, ugukoresha amavuta y’ibinyabiziga bizokwongerwa, kandi uguhungabana kw’imodoka na kwo nyene kuzoba gukomeye.
Eka ikigereranyo kivanga
Igishushanyo kivanga ni ikigereranyo c’inzira hagati y’igishushanyo gisanzwe n’igishushanyo c’umusaraba. Irangwa n’imirongo y’imirongo mitoyi ifise inzira zitandukanye canke ahanini mu burebure hagati y’uruzitiro, n’imirongo y’imirongo yagutse ifise inzira zitandukanye canke cane cane ku mpande zompi. Ubwo bwoko bw’uguhuza butuma urugero ruvanze rugira ubushobozi bwiza muri rusangi n’ubushobozi bukomeye bwo kwimenyereza. Ntibibereye gusa ku nzira nziza cane, ariko kandi n’ibarabara ry’amabuye ry’agaciro, n’ivyuma vy’amabuye vy’agaciro. Ivyo gufatanya ni vyiza kuruta ivy’ibigereranyo bisanzwe, ariko ubushobozi bwo kwambara ni buke gatoyi. Amakamyo amwe amwe n’imodoka zitwara abantu n’amaguru zine zikoresha ubwo bwoko bw’amapine y’amaguru.
Igishushanyo c'uburongozi bumwe
Igishushanyo kimwe ni uko imirongo yose ifatanye, ikaba ari imiterere y’amabuye yigenga. Irafise ubushobozi bwiza cane bwo guhagarika, n’uguhagarara neza cane mu bihe vy’imvura, bibereye gutwara imodoka yihuta cane. Ariko rero, ikibanza co gushiramwo amapine gitegerezwa kuba kimwe n’inzira yo gutwara. Ibereye imodoka zigenda zigenda cane.
Igishushanyo
Ivyo bikoresho vyose birahuzwa, bikaba bikora imiterere y’amabuye yigenga. Ifise ubushobozi bwo gukora neza no gukoresha neza, gufata neza no gushikama ku nzira z’urubura n’amazi, n’ubushobozi bwiza bwo gukura amazi mu bihe vy’imvura. Ariko imiterere yayo yigenga ifise ubushobozi bwo kwambara nabi. Scope y’ugukoresha: amapine yose y’imiduga yose n’urubura, amapine y’inyuma y’imodoka y’ubudandaji.
Igishushanyo
Ico kigereranyo c’uburinganire gifise ibigereranyo bitandukanye ku mpande z’ibubamfu n’iz’iburyo z’uruzitiro. Kubera ko bituma umuntu agira umuvuduko w’inyuma w’ico kigereranyo iyo ihindukiye, iratuma igikorwa co guhindura umuvuduko kirushiriza cane kandi kigatuma umuntu ashobora guhangana n’ibintu vy’inyuma. Ariko utegerezwa kwitwararika ubuyobozi bubereye bw’ipine. Ni vyiza cane ku modoka zihiganwa n’imiduga ikora neza cane
