Development of Strategies to Promote and Facilitate the Implementation of the Asian Highway Design Standards

The Asian Highway Network is a coordinated plan for the development of highway routes of international importance with a view towards promoting and developing international road transport in the region. Since the Asian Highway network was adopted in 2003, it has already played a pivotal role in assisting member countries in improving intercountry and interregional transport links.

The Asian Highway classification and design standards provide the minimum standards and guidelines for the construction, improvement and maintenance of Asian Highway routes. According to the Intergovernmental Agreement on the Asian Highway network, Parties shall make every possible effort to implement the design standards. However, the quality of the Asian Highway network across member countries is uneven. The latest 2017 updates show that to date about 9,176 km, i.e.7.25 per cent, of the network do not yet meet the minimum desirable standards. An ESCAP estimation shows that upgrading different classes of the Asian Highway network to higher quality standards needs a considerable amount of investment estimated at US$ 51.4 billion in 2017.

A survey was conducted by the ESCAP secretariat to study status of implementation of the Asian Highway design standards in the member countries in June 2017. The survey results indicated that member countries encounter several challenges to implement the Asian Highway design standards. Lack of funding is the most critical challenge. Lack of awareness as well as lack of planning and coordination also hinder the development of the routes as well as implementation of the Asian Highway design standards.
