Sustainable mobility planning at regional and local level has been rapidly gaining ground in the last decade. After joining the EU, this integrated approach to transport planning began to be implemented in Slovenia as well, and in the last decade the development of this area has experienced rapid progress. Nowadays, more and more municipalities respond to the incentives of the EU and of the Ministry of Infrastructure and are preparing and implementing Sustainable Urban Mobility Plans (SUMP), which are the central tool of the Sustainable urban mobility planning. SUMP is a strategic document which outlines the municipality´s vision and objectives in the field of sustainable mobility and a list of necessary actions which help achieving a comprehensive change and, consequently, a higher quality of life. The implementation of the strategy has already brought important results to some municipalities in solving mobility problems, which is a good incentive for other municipalities.
