SPATIAL ANALYSIS OF TRANSPORT MODE CHOICE AND TRAVEL BEHAVIOUR IN INDO-BURMAN BORDER: A CASE STUDY OF AIZAWL CITY, MIZORAM

This study investigates the spatial determinants of transport mode choice and travel behaviour in Aizawl City, located in the Indo-Burman border region of Northeast India. As a hill city constrained by rugged topography and limited developable land, Aizawl presents unique challenges to urban mobility and accessibility. Using Multinomial Logistic Regression (MNLR), this research examines how spatial attributes, such as elevation, slope, population density, road density, traffic congestion, and proximity to transport facilities, affect the probability of commuters adopting specific modes of travel, including public transport, private vehicles, and walking. Primary data from household surveys were integrated with geospatial layers using ArcGIS to derive spatial variables. Results indicate that proximity to bus stands, slope gradients,and road density are the most influential factors shaping travel behaviour. Steeper slopes and greater elevation discourage non-motorized mobility, while high road density and moderate population density support higher transport diversity. Areas distant from transport facilities exhibit stronger reliance on private vehicles and intermediate modes,especially two-wheeler taxis. The findings emphasize that urban form and terrain directly condition accessibility and mode choice in hilly environments. The study contributes to spatial transport modelling literature by illustrating how built environment and topographical constraints influence daily mobility in small but growing border cities. Recommendations highlight the need for terrain-sensitive planning, improved public transport accessibility,and non-motorized connectivity enhancement for sustainable mobility in similar hill city contexts.
