Transport Models to Generate Inter-Regional Flows A Review and an Operational Transport Model for India

Abstract

This paper develops an operational interregional transport model for India that integrates transport demand forecasting with macroeconomic and spatial planning objectives. Building on a review of established transport models, the study proposes a framework that allocates national output and demand to regions using the Shift and Share method, estimates regional demand through income and population elasticities, and generates interregional flows via entropy-based gravity models. Empirical data on regional characteristics, commodity movements, and transport costs underpin the model’s implementation. By explicitly incorporating spatial dimensions and interregional linkages, the model provides a systematic tool for evaluating transport requirements, optimizing modal choices, and supporting informed policy decisions aimed at balanced regional development and efficient transport planning in India.
