The rapid proliferation of new technologies and disruptive innovations are threatening well established players across many sectors. None more so than in the mobility sector, where the public and private provision of passenger and freight transport is undergoing a mobility revolution. To ensure maximum benefit from innovation in mobility, the right regulatory framework conditions and cooperation between public authorities and industry, business and operators is needed. The overall goal of GECKO (Governance principles and mEthods enabling deCisions maKers to manage and regulate the changing mObility systems) is to support authorities in developing the most appropriate regulatory framework and governance model, through guidance, recommendations and case studies, for the transition to a new mobility era of cooperative, inclusive, competitive, sustainable and interconnected mobility across all modes, through evidence-based research.
