Zagreb is one of five members of the CIVITAS ELAN project, which aims to help developing cities implement sustainable, clean mobility solutions for passenger and freight traffic. As part of this project, the city of Zagreb is planning to build an intermodal transport terminal at the Sava Bridge. WYG’s task was to prepare Terms of References for a feasibility study with cost-benefit analysis for this project. After a detailed review of EU co-financed intermodal terminals, the team of six key experts provided the city with a document including instructions on how to prepare the feasibility study, including conceptual design, traffic models, and environmental impact assessment.
