A GIS-Based Approach to Solve Sustainable Port-Hinterland Connectivity by Proposing Optimal Locations of Dry Port Using a Location-Allocation Model

The paper disseminates the knowledge of Dry Port Planning in the shadow of the seaport. For the planning of dry port location, land suitability analysis, and location-allocation analysis, considering parameters such as population density, accessibility, proximity to production centers, and avoidance of existing infrastructure have been carried out. The weighted sum tool technique is used to combine these parameters. The weights are assigned using the ‘Analytical Hierarchy Process’ (AHP). Also, the service area analysis is made to check the service area reach of each proposed dry port location. This analysis identifies the optimal locations of dry ports and includes a comparative study to assess the effectiveness of the proposed rail connectivity solution in relation to freight traffic circulation through the road network. The study reveals significant reductions in greenhouse gas emissions and transportation costs. Effective location planning for dry ports is essential for enhancing trade efficiency, optimizing transportation operations, driving economic development, and promoting sustainable port cities.
