What it means
IRC traces its origin to the first Highway Engineers' Meeting, convened by the Central Government in New Delhi on 10 December 1934. Its publications are known as IRC codes or IRC special publications, and they cover geometric design, pavements, bridges, road signs, markings and road safety.
How it applies in India
Road agencies and NHAI contracts refer to IRC codes for civil and safety work, so a traffic technology project meets them at the edges: gantry structures, sign and marking layouts near cameras, lane widths and clearances, and work zone safety during installation. When a tender lists IRC codes, check which edition it names and which items apply to the systems you supply. IRC codes do not certify cameras or analytics. Device testing comes from bodies such as STQC, BIS and test centres such as NATRAX.
