What is DDHI?

The Data-Driven Hyperlocal Intervention (DDHI) framework is a structured, district-specific road safety initiative developed by the Centre of Excellence for Road Safety(CoERS) at IIT Madras under the aegis of the Ministry of Road Transport and Highways (MoRTH), Government of India.

Hyperlocal interventions are crucial for enhancing road safety outcomes on the ground. While crash data provides patterns, effective action requires an understanding of the district-level context, where risk factors, road behaviour, and system readiness differ.

DDHI framework and tools assist the District Road Safety Committee (DRSC) of 100high crash burdened Districts to identify human factor road safety issues, assess opportunities to improve at the hyper local level, plan suitable low-cost, high-impact road interventions, track implementation and assess impact.

About RBG Labs

The Rehabilitation Bioengineering Group (RBG Labs) was established in 2006 at the Department of Engineering Design, IIT Madras, under the leadership of Prof. Venkatesh Balasubramanian. The lab applies a data-driven systems approach across road safety, human factors engineering, driver behavior, lean manufacturing, and policy support. Over the years, it has grown into a national reference centre for evidence-based innovation and capacity building in transport and safety systems.

In collaboration with the Ministry of Road Transport and Highways (MoRTH), RBG Labs developed the electronic Detailed Accident Report (eDAR/iRAD), India’s first national crash database, now deployed across all 36 States and Union Territories. The lab also anchors the Centre of Excellence for Road Safety (CoERS), integrating research in human factors, road engineering, and vehicle safety to strengthen systemic outcomes.
