Iyunguruzo ryo mu modoka: Ikintu nyamukuru co kumenya neza ko umuyaga wo mu modoka umeze neza

Mu modoka zo muri iki gihe, naho nyene icunguruzo ry’umuyaga ryo mu nzu risa n’iridahambaye, rirafise uruhara runini mu kubungabunga amagara meza kandi umuntu ashobora gutwara neza.
Igikorwa nyamukuru c’iyunguruzo ry’umuyaga wo mu modoka ni ugucungera umuyaga winjira mu modoka. Ifata neza ibintu bishobora gutera ingorane nk’inkungugu, amabara y’ibimera, umwotsi, na PM2.5, bikabuza ivyo bintu bihumanya kwinjira mu ndege biciye mu kirere-gikoreshwa n’umuyaga, gutyo bikaba bituma abagenzi bashobora guhema neza. Ico gikorwa co kuyungurura ni ikintu gihambaye cane cane mu bibanza bishobora guterwa n’umwotsi, canke inyuma yo gutwara imodoka mu bibanza vy’ubwubatsi canke mu mabarabara arimwo inkungugu.
Uretse ko iyo nyungura y’umuyaga yo mu nzu iyungurura inkungugu n’ibintu bihumanya, iragabanya n’iminuko. Inywa iminuko iri mu kirere, nk’iminuko y’ibiva mu modoka be n’iminuko y’imyanda, ivyo bikaba bituma ikirere kiri mu modoka kiguma ari ciza. Ikindi kandi, akayunguruzo k’umuyaga wo mu nzu y’indege gasukuye karafasha ivyuma bikoresha umuyaga gukora neza, bikagabanya ukuntu ubushobozi bukora neza be n’ugukoresha inguvu nyinshi bitewe n’ukwirundanira kw’inkungugu, kandi bigatuma ivyuma bimara igihe kirekire.
Ariko rero, iyo ncunguru y’umuyaga yo mu nzu y’indege irakeneye gusubirwamwo ubudasiba. Muri rusangi, bivanye n’aho umuntu ari be n’ingene akoreshwa kenshi, birakenewe ko umuntu ayisubiriza inyuma y’ibilometero 10.000 gushika ku bihumbi 20, canke inyuma y’amezi atandatu gushika ku mwaka umwe. Nimba ukunda gutwara imodoka ahantu hahumanye cane, igihe co gusubirira iyo modoka gikwiye kugabanywa. Iyo icunguru ry’umuyaga ryo mu nzu y’indege ridasubirijwe igihe kirekire, rizozibira, bikagabanya uruja n’uruza rw’umuyaga kandi bikagabanya ubushobozi bwo gukonjesha no gushusha.
