ROUTE ALIGNMENT PLANNING IN GIS

Abstract

Route alignment planning for a new highway on the regional level constitutes a complicated planning process, which involves the consideration and analysis of various data sets. It also includes the development of alternative corridors for the planned transport link and the evaluation of socio-economic and environmental impacts of different alternatives. Usually in most developing countries, these tasks are under implementation using traditional approach of manual systems. In the present work a methodology comprising of various parameters such as slope, soil, geology, drainage, land use/ land cover is used to determine the best possible route between source and destination is proposed. A multi-criteria weighted algorithm is prepared to build expert systems so that decision making techniques have been systematically used to identify route alignment.
