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 – Efficiency is defined as the ratio of output through input. Something can be described as more energy efficient if it delivers more services for the same energy input or the same service for less energy input.

Economic efficiency refers to maximising the benefits that users can gain from the use of a service after taking account of the costs of provision and operation. For example, an efficient public transport system facilitates fast and seamless movement within and between cities at an acceptable cost for the population, which in turn is essential for urban functionality and prosperity.

Relevance to SUMP – One of the five principal objectives of SUMP is to improve the efficiency and cost-effectiveness of the transportation of people and goods. Energy-efficient transport offers huge potential for reducing the demand for oil and for energy in general. Energy-efficient transport can be encouraged on three levels: (i) system efficiency - organise land use and social and economic activities in such a way that the need for transport and the use of fossil fuels is reduced; (ii) travel efficiency - make use of energy-efficient modes like public transport and non-motorised modes to reduce energy consumption per trip; and (iii) vehicle efficiency - consuming as little energy as possible per vehicle kilometre by using advanced technologies and fuels and by optimising vehicle operation.
