Urban mobility planning is a challenging and complex task. Planners need to manage many, sometimes conflicting demands and requirements on the local level and even beyond when it comes to contributing to European climate change and energy efficiency targets. The complexity increases in case of political change and, as is currently the case in many European countries, severe financial constraints. The guidelines are the result of a thorough and European-wide expert consultation process organised between 2010 and 2013 as part of a service contract for the European Commission. They define a Sustainable Urban Mobility Plan as a strategic plan designed to satisfy the mobility needs of people and businesses in cities and their surroundings for a better quality of life. Such a plan should not be considered as “yet another plan”. Instead, a Sustainable Urban Mobility Plan should build on existing planning practices and take due consideration of integration, participation, and evaluation principles.
