Citizens must be involved in creating and enhancing policies that promote sustainable mobility. The goal is not just to address the demands of users but also to help find strategies for altering ingrained patterns and habits related to transportation behavior. The main factor influencing whether environmental results, including transportation, are positive or negative is human behavior, whether at work or in their free time. In order to understand users’ motives in relation to policy objectives, it is crucial to include them in the policy-making process. Sustainable mobility will benefit from taking an ecologically responsible stance. This paper presents several sustainable mobility interventions derived from a citizen engagement process. The methodology involved organizing four (4) citizen panels in the West Midlands, UK, where participants completed specific exercises. Specifically, the steps were as follows: i) Defining the visions – long-term direction, ii) Participatory diagnosis of transport policies, iii) Decision on priorities, and iv) Designing of actions. The findings revealed that two main citizen behaviors need to be targeted by future sustainable mobility policies. These relate to changing automatic or habitual car users’ behaviors to encourage more active travel and parents of young families to provide alternate options for their children’s safer and more autonomous school transportation.
