After plan adoption, the implementation phase starts. As the Sustainable Urban Mobility Plan is a strategic document, it provides a sound framework for these activities, but it does not specify in detail how a measure will be implemented. It needs to be stressed that the implementation process also needs to follow a structured approach to refine targets and to plan, detail, manage, communicate and monitor the implementation of measures. These management cycles will be much shorter than the planning cycle and need to be flexible enough to adapt to new situations. They need to be institutionalised in the organisation that is in charge of implementing a measure.
