These Guidelines present Sustainable Urban Mobility Planning as a strategic and integrated methodology which aims at improving accessibility and quality of life through a shift towards sustainable mobility. These Guidelines intend (i) to identify the challenges in urban transport planning and ASEAN policies related to urban mobility and (ii) to create awareness among the actors for further discussions on the required preconditions, competencies, and capacities to conduct a Sustainable Urban Mobility Planning process. A step-by-step orientation, which is divided into four (4) phases of the planning process, tailored to current planning practices and resources in the region, is introduced as well as the main products within the different steps of the planning process. For each phase, the Guidelines provide common definitions, examples, lessons learnt, best practices and recommendations on different aspects of the planning process while considering different institutional, environmental, and social contexts and conditions.
