Ikiraro cyicyuma kirinda ibyuma ntigifite ubwiza buhebuje nuburyohe bugezweho bwimiyoboro idafite ibyuma, ariko kandi ifite ubukana bwimiyoboro isanzwe ya karubone. Nibisimbuza imiyoboro ihenze idafite ibyuma. Ihujwe ninkingi zicyuma kugirango ikore umutekano mumijyi, imihanda nibiraro, nibindi. Ntabwo ikomeye kandi itanga gusa, ariko kandi irashobora gushushanywa muburyo butandukanye, igaha umujyi ibyiza nyaburanga.
Ibisobanuro rusange biranga ibyuma birinda ibyuma:
1. Uburebure busanzwe bwizamu: 3000mm
2. Uburebure busanzwe bwa guardrail: 600mm 700mm 800mm 900mm 1000mm (birashobora guhindurwa ukurikije ibyo usabwa)
3. Inkingi: isahani yicyuma yasuditswe
4. Umuyoboro wo hejuru utambitse: 89mm
5. Umuyoboro wo hasi utambitse: 63.5mm
6. Shingiro: isahani yicyuma yuzuyemo base beto
