India’s first ever Highway Capacity Manual

The Minister of Road Transport & Highways, Shipping and Water Resources, River Development and Ganga Rejuvenation Shri Nitin Gadkari released India’s first ever Highway Capacity Manual in New Delhi today. The manual, known as Indo-HCM, has been developed by CSIR – CRRI on the basis of an extensive, country-wide study of the traffic characteristics on different categories of roads like the single lane, two-lane, multi-lane urban roads,  inter-urban highways and expressways and the associated intersections on these roads. The study involved seven academic institutions including IITs at Roorkee, Mumbai, and Guwahati, School of Planning and Architecture, New Delhi, Indian Institute of Engineering and Science and Technology, Shibpur, Sardar Vallabhai Patel National Institute of Technology, Surat and Anna University, Chennai.

About Indo- HCM:

The manual has been developed by CSIR-CRRI on the basis of an extensive, country-wide study of the traffic characteristics on different categories of roads like a single lane, two-lane, multi-lane urban roads, interurban highways and expressways and the associated intersections on these roads. It will guide road engineers and policymakers about road expansion.

The manual lays down guidelines for when and how to expand or manage different types of roads and their intersections and the level of services to be put in place. It has been developed based on the unique nature and diversity of traffic on Indian roads.

Benefits of this manual:

India was among the very few South Asian countries which did not have the practice of having a country-specific HCAP manual. The US and Danish authorities had pioneered the practice of having a key document to set highway construction standards all across their countries. This manual would now help in the scientific planning and expansion of road infrastructure in the country.
