Scenario-based analysis for intermodal transport in the context of service network design models. (September 2019) - Tawfik, Christine
Abstract: In this paper, we discuss service network design models for consolidation-based freight transport systems. Two path-based formulations are presented for the domestic and long-corridor cases, respectively. In the context of intermodal transport as a relevant application, the modelling frameworks are applied in Belgium-related case studies, in order to draw meaningful managerial insights. Several future scenarios are experimented by analysing a number of parameters that have been identified as significant operational factors and policy levers. The results underline the costly position of rail transport and a clear economic favouring of inland waterways (IWW), potentially attributed to the high rail fixed costs. Additionally, it is suggested that intermodal transport can benefit from rail subsidies, especially during the early stages of covering the market. Even in the best-case scenario, the resulting modal shares are far from reaching the figures desired for freight transport in the EU. Thus, more powerful instruments need to be implemented to promote greener transport schemes. Highlights: Service network design models are developed for consolidation-based freight transport systems Introducing path-based formulations with minimum utilization and resource balancing constraints. Conducting a scenario-based assessment of the future position of intermodal transport within Belgium-based case studies The results stress the costly position of rail-based transport and the economic favour of inland waterways transport. Rail subsidies are an essential competitiveness instrument but not powerful enough to achieve the target modal split figures in Europe.
