Sustainable rural mobility: Strategic impact of integrating light rail into multimodal networks

Rural multimodal transport plays a crucial role in enhancing regional connectivity, fostering economic growth, and promoting environmental sustainability. This paper presents a methodology to evaluate the feasibility of light rail systems in rural networks, illustrated by a case study in Occitanian, France. Using a multimodal network flow model, we provide a methodology for assessing the operational, environmental and economic impacts of the possibility of operating new light rail systems, with a particular focus on the role of transshipment in optimising transport flows. Our approach demonstrates the potential to reduce carbon emissions, improve transport efficiency and maximise infrastructure utilisation based on key performance indicators specific to rural areas. Our methodology allows for sensitivity analysis of strategic scenarios, providing valuable insights for policy makers. Using a fictitious case study, it demonstrates that a path to sustainable and cost-effective rural mobility is possible by balancing efficiency, environmental impact and economic viability through optimised intermodal synergies.
