Towards transformation-oriented planning: what can sustainable urban mobility planning (SUMP) learn from transition management (TM)?

Abstract

The European Commission’s concept of Sustainable Urban Mobility Planning (SUMP) aims to prepare transport planners for the challenge of fundamental transformations to achieve climate-neutral and sustainable cities. While the concept has been widely adopted by European cities over the last decade, it can be asked whether SUMP is able to trigger the required transformative change in mobility systems. This paper critically reflects on the SUMP concept by systematically comparing it with the theoretical governance framework of Transition Management (TM), which is explicitly designed to foster transformative change. Based on a literature review, we examine similarities and differences between these approaches regarding the planning dimensions of context, content and process. Drawing on this comparison, the paper demonstrates how SUMP could learn from TM in practice and research in four main ways: (i) utilising transition theory to better address transition features; (ii) using collaborative formats from TM while taking account of legitimacy concerns; (iii) incorporating backcasting approaches; and (iv) explicitly integrating experiments into the process cycle. The paper exemplifies how insights from transition research can stimulate the further development of procedures, methods and tools towards transformation-oriented planning.
