Amabhodi okupaka, amabhodi abahamba ngezinyawo kanye namabhodi okuvikela ahlinzekwa yi-RICJ izindlela ezisebenzayo zokulawula isiminyaminya sezimoto noma sabahamba ngezinyawo futhi kuvinjelwe izingozi. Amabhodi ethu okupaka ayatholakala ngensimbi engagqwali eqinile noma ngensimbi ye-carbon futhi agxilile, ayasuswa, ayahlukaniseka, ayagoqeka futhi asekela namalogo ngokwezifiso. Lawa ma-bollards alungele ukulawula ithrafikhi nokuchaza umgwaqo wabahamba ngezinyawo nabashayeli. Inani elikhulayo lezikhungo zengeza ama-bollards kakhonkolo nama-bollards ensimbi aqinile ngenxa yezizathu zokuphepha.
