The aim of the SUMP Glossary is to provide a brief explanation of specialist words, terms and abbreviations relating to the subject of sustainable urban mobility planning. The Glossary has been prepared by the CH4LLENGE project and as a result, there is a particular focus on defining terms relating to the four key challenges of plan development studied by the project, namely: participation, cooperation, measure selection and monitoring & evaluation. It is envisaged that, over time, the international community of mobility practitioners will add to the content of the online Glossary and produce versions in different languages.
A simple structure has been followed so that users can search for words, terms and abbreviations in a standard alphabetic format. For each Glossary term, the following information is provided:
• a general definition and, where available, a specific definition relating to transport and mobility planning;
• an explanation of why the term is relevant to sustainable urban mobility planning; and
• references to sources.
The preparation of the Glossary, including the selection of terms and drafting of definitions, has been informed by a review of relevant reports, guidance documents and existing glossaries. The key reference is the European Union “Guidelines - Developing and implementing a Sustainable Urban Mobility Plan” prepared for the EC’s Intelligent Energy Europe (IEE) programme by Rupprecht Consult (January 2014) and therefore this has not been identified as a source throughout the document. The outputs of the CH4LLENGE project have also provided a principal source of information and the official documents can be found at www.sump-challenges.eu.

Please note that not all the explanatory text is taken directly from the listed sources. The authors have sought to take established definitions and information as the basis and explain these in simple terms and relate them to the context of sustainable urban mobility planning where this was not previously the case.

Definition – Decision making is the act or process of making decisions, by whatever means.

Evidence-based decision-making is intended to help policyinfo-icon makers maximise the benefits of their investments and to prevent investment in measures or projects that fail to address critical problems. Ideally, decisions should be based on the ex-ante appraisalinfo-icon of the predicted effects of a plan, measureinfo-icon or package of measures. There is a tendency in transport decision making to assess measures more narrowly, based on pre-conceptions and with a focus on direct economic effects, an approach which can favour traditional transport measures.

Relevance to SUMP – In SUMP, the decision maker is typically an organisation (e.g. a committee of the city council) or person in a high-level position (e.g. mayor or senior executive), with the responsibility to adopt a SUMP or approve a measure. Decision making usually comes after the use of various project management and participationinfo-icon tools. The main characteristics of SUMP preparation, including participation, integrationinfo-icon and consideration of external costs for all modes, should extend through to the decision-making stage. For example, engaging citizens and a wide range of stakeholders through a participation process in the preparation of a SUMP is viewed as fundamental to ensuring the legitimacy and quality of the decisions made. Moreover, public authorities should ensure maximum transparencyinfo-icon and enable more democratic, participatory decision making processes. For example, a referenduminfo-icon vote could be held in relation to the approval of major transport measures.
