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

摘要

Contemporary methodologies are not conducive to requirements of the district level transportation planning. Therefore this paper proposes a computer-aided methodology for planning and prioritizing district transportation networks. The methodology has two versions, one for developed areas and another for underdeveloped areas. Establishing interactive relationships among transport networks, costs and benefits are unique features of the 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.
