International intermodal container shipping network in South Asia: modelling and policy simulations

This paper focuses on the international intermodal container cargo shipping network in South Asia. A two-layered network assignment model of international container cargo is applied to this region for simulating the impact of policies designed to increase the level of international logistics infrastructure. The first simulation, which focuses on the improvements of the road and rail networks around the largest port in this region (Jawaharlal Nehru Port Trust, or JNPT), reveals that Indian west coast ports are very competitive in acquiring cargo both originating from and destined to Delhi. More importantly, these west coast ports face critical capacity constraints for hinterland shipping around JNPT. The second simulation estimates the effect of the recommencement of the international ferry connecting South India and Sri Lanka and suggests that the reduction of cross-border barriers and improving connected rail services are essential for promoting the international ferry service.
