Asian Highway Design Standard for Road Safety: Design Guidelines

This document consists of recommended guidelines related to the “Asian Highway Design Standard for Road Safety” to the Intergovernmental Agreement on the Asian Highway Network.

While the guidelines are not mandatory in nature, the member countries of the Asian Highway network are encouraged to refer to the principles and recommendations given in the document for new road projects and improvements of existing sections of Asian Highway routes under their jurisdiction.

Due to the diverse circumstances of the Asian Highway Network, the adoption of particular recommendations would need to take into account prevailing social, economic and technical considerations.

In all cases, sound engineering skills are required to formulate specific solutions to address project issues which could be complex in reality. Flexibility and innovations are desirable as far as safety performance is not undermined and consistency is reasonably maintained.
