The CAREC Road Safety Engineering Manual provides guidance on identifying, investigating, and addressing hazardous road locations, or blackspots, in Central Asia Regional Economic Cooperation (CAREC) countries. The manual is aimed at road safety engineers, planners, municipal engineers, traffic police, consultants, and representatives of design institutes and other agencies. It shows how to identify blackspots, crash patterns, and contributing factors, and how to assess which blackspots removal programs should prioritize. The manual includes case studies on proven ways of reducing crashes and highlights the importance of crash data. Investing in addressing blackspots can save lives, prevent injuries, and return major economic benefits to CAREC countries. The Central Asia Regional Economic Cooperation (CAREC) Program is a partnership of 11 member countries and development partners working together to promote development through cooperation, leading to accelerated economic growth and poverty reduction. It is guided by the overarching vision of “Good Neighbors, Good Partners, and Good Prospects.” The Asian Development Bank serves as the CAREC Secretariat.
