ABSTRACT

 

Road networking serves as lifeline in a country or region, and well connected roads, adequate density, and regular maintenance may contribute to the socio-economic growth. It is necessary that a road network should offer all-weather connectivity throughout the year. However, in the Ladakh province of Jammu and Kashmir, India, where road is the only way of civilian transportation, do not offer all-weather connectivity because of its extreme climatic conditions and difficult terrain. The major objective achieved in this study was to (i) evaluate the existing road network in the region and (ii) to propose alternative road network with necessary modification on sound scientific basis using GIS and remote sensing techniques. The existing road network of Ladakh province has been evaluated in the pretext of different agents like socio-economic, physiognomic and climate factors. Drivers have been identified and their preference has been assigned through multiple hierarchal process using AHP. Finally an alternative road network has been derived using object-based modelling approach in GIS domain, with 13% overall change compared to existing road. Suggested road network can diminish the extra effort to approach an inaccessible area in adverse weathering conditions with least investment of time and wealth. Although the results are subjected to various inputs for any other region with similar topography and climatic conditions.
