Developing a computer-aided methodology for district road network planning and prioritization in Nepal.

Contemporary methodologies are not conducive to the requirements of district level transportation planning. This paper proposes a computer-aided methodology for prioritizing and planning district transportation networks. The methodology has 2 versions, one for developed areas and another for underdeveloped areas. Establishing interactive relationships among transport networks, costs, and benefits are unique features of methodology designed for developed areas. A simplified version of the methodology is introduced for underdeveloped areas. The GIS supported and spreadsheet based methodology is useful for planning the district level road networks in Nepal and other developing countries.
