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 – Modal shareinfo-icon can be defined as the share of people using a particular mode of transport (including cycling and walking) within the overall transport usage of an urban area. Modal share can be calculated for passenger and freight (logistics) transport based on different units, such as number of trips, volume, weight, passenger-km or tonne-km. The modal share of different modes of transport is typically displayed as a percentage value for each mode. Modal share can be measured for specific trip types (e.g. journeys to work) or for the total of all journeys taken in a city for a given period of time. A challenge that still needs to be addressed is accurately counting intermodal journeys. Most journeys are simply attributed to the longest portion (e.g. a two km bike ride to the train station followed by a 15 km train journey and a 10-minute walk is often only counted as a train journey).

Relevance to SUMP – Modal share can be utilised as an indicatorinfo-icon when a public authorityinfo-icon preparing a SUMP is analysing the current mobilityinfo-icon situation, developing targets and undertaking monitoringinfo-icon and evaluationinfo-icon.
