GLOSSARY TERMS

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 – A scenarioinfo-icon is a description of possible actions or events in the future, such as a possible future set of demographic and economic conditions.

Relevance to SUMP – When developing a strategyinfo-icon, the planning authorityinfo-icon should consider the changing context for mobilityinfo-icon in the future. One problem when developing a SUMP for a long timeframe (e.g. 15 years) is that the context becomes less certain. The principal uncertainties typically relate to changes in economic and demographic factors, such as changes in population, household size and income levels. The direction and pace of technological change is a further uncertainty. Developing a range of scenarios based on population and economic projections enables planners to undertake an appraisalinfo-icon of the performance of alternative mobility strategies under different future conditions. Scenario appraisal normally involves consideration of a “business as usual” baselineinfo-icon case. This assumes that future economic and transport trends follow those of the past and that no changes in mobility policyinfo-icon take place.
