This report details how REBALANCE aims to re-shape the current mobility culture towards a new culture that better meets the inherent values of the European population while addressing the environmental, energy, social and economic challenges it may face. The objective of this report is to elaborate a Policy Roadmap following the Policy Guide through a back-casting exercise, where the transport and mobility future envisaged in WP4 (the Needs and Hopes of the Future / The Vision) will be set out and, throughout the task, the policies, and programs connecting the envisaged future to the present, as described in WP3 (The Language of the Present / The Claim), will be identified. A relevant Policy Roadmap suggesting reviewed and updated Policy Guidance will be defined combining soft/hard & short-term/long-term policies: reflected in soft policies such as better information, communication, and education (“nudges”), as well as regulatory changes, key incentives and subsidies. Changes in the official Cost-Benefit Analysis guides and other impact assessment methods will be proposed to European institutions and authorities responsible for transport and mobility-related initiatives. As an outcome of the back-casting exercise, the policy roadmap consists in a set of concrete policy measures and their associated timelines targeting the proposed strategy of task 5.2 (Guidance for infrastructure and investment policies). The policy roadmap integrates additional policy guidance that develops the political process necessary to complete the strategy. The roadmap was elaborated by involving, in a collaborative workshop and through a series of surveys, not only 8 members of the REBALANCE project but also 12 international experts from different backgrounds and profiles (scientists, decision-makers, stakeholders, private partners, associations…). The result represents a certain consensus, but also generates extensive discussions and further debate on a number of topics.
