Geographic Information System (GIS)Abstract
This study identifies optimal metro network locations in Tiruchirapalli city to address current and future transportation challenges. The research leverages Remote Sensing, Geographic Information System (GIS), and the Analytical Hierarchical Process (AHP) to assess and prioritize key factors influencing site selection. Criteria such as population density, traffic hubs, intersections, existing road networks, land use, and slope maps are systematically analyzed. Each factor is ranked based on its importance and weighted using AHP. A GIS-based weighted overlay method integrates these ranked criteria to identify potential routes for the metro system. The study proposes five routes spanning southwest-north and east-west directions, connecting critical origin and destination stations. The findings provide a strategic framework for sustainable urban transportation planning in Tiruchirapalli, ensuring efficient connectivity while addressing the city’s evolving transit demands.
