Izinciphisajubane, ezaziwa nangokuthi izinciphisajubane, ziyizinsiza zethrafikhi ezifakwe emigwaqweni emikhulu ukuze zihambe kancane ezimotweni ezidlulayo.Umumo ngokuvamile ufana ne-strip, kodwa futhi ufana nephoyinti;impahla ngokuyinhloko irabha, kodwa futhi metal;ngokuvamile ophuzi nomnyama ukuze ahehe ukunakwa okubonakalayo, ukuze umgwaqo ukhonjiswe kancane ukuze kuzuzwe inhloso yokwehla kwezimoto.Ibhande lenjoloba lokunciphisa izinga lenziwe ngezinto zenjoloba, isimo siwumthambeka, umbala uvame ukuphuzi futhi ube mnyama, futhi unamathele ezimpambanweni zomgwaqo ngezikulufa zokunweba, okuyindawo yokuphepha yokunciphisa imoto.Igama lesayensi libizwa ngokuthi i-rubber deceleration ridge, eklanywe ngokuvumelana nesimiso se-engeli yesondo kanye nerabha ekhethekile ephansi lapho imoto isebenza, futhi yenziwe ngerabha ekhethekile.Iwuhlobo olusha lwedivayisi yokuphepha eqondene ngqo nethrafikhi efakwe ekungeneni ezimpambanweni zemigwaqo enguthelawayeka, izimboni nezimayini, izikole, izindawo zokuhlala, njll. ukuze kuncishiswe isivinini sezimoto kanye nezimoto ezingezona izimoto.
Izidingo ezijwayelekile zamabhampa esivinini senjoloba (ama-ridge):
1. I-rubber deceleration ridge kufanele yakheke ngokuhlangene, futhi indawo yangaphandle kufanele ibe nemigqa yokwandisa ukunamathela.
2. Iyunithi ngayinye ye-deceleration ridge kufanele ibe nezinto ezibonisa i-retro-reflective okulula ukuzibona ebusuku, zibheke lapho imoto ishayela khona.
3. Akufanele kube nama-pores ebusweni, akufanele kube khona imihuzuko ecacile, ukuntuleka kwezinto ezibonakalayo, umbala kufanele ube umfaniswano, futhi akufanele kube khona ukukhanya.
4. Igama leyunithi yokukhiqiza kufanele licindezelwe ebusweni be-raber deceleration ridge.
5. Uma ixhunywe emhlabathini ngama-bolts, izimbobo ze-bolt kufanele zibe izimbobo eziphikisayo.
6. Iyunithi ngayinye ye-ridge ye-deceleration kufanele ixhunywe ngendlela ethembekile.
Ingxenye ephambanayo yeyunithi yeriji yokuhlehlisa ububanzi nezikhombisi-ndlela zobude kufanele ibe yi-trapezoidal noma emise okwe-arc.Ubukhulu bobubanzi kufanele bube phakathi kwebanga elingu-(300mm±5mm)~ (400mm±5mm), futhi ubukhulu kufanele bube phakathi kwebanga elingu-(25mm±2mm)-(70mm±2mm).Isilinganiso sobubanzi nosayizi akufanele sibe ngaphezu kuka-0.7.
I-speed bump efanelekile yerabha-yepulasitiki kufanele iqinisekise ukuthi imoto ngeke iphelelwe ukulawula lapho imoto idlula, futhi izingxenye ezibalulekile zokuphepha ngeke ziphuke nezinye izimo eziyingozi, futhi kufanele zibe nokuphepha okuphezulu nokuphepha kwesakhiwo.
