In 2016, 152 Municipalities were selected for funding in order to develop their SUMPs. The European SUMP Guidelines give a structured framework for the technical implementation of a SUMP but as each Country, Region and local area has its own particularities, the Greek Ministry of Transport decided to develop some horizontal National Directions in order to support Greek areas (Municipalities, Metropolitan areas or Regions) that decide to develop a SUMP in order to ensure a high quality of the final plans and also a short term display of their positive effects. The Directions cover aspects such as internal organization of the local supervising authority, preparatory actions, staff qualifications and data needed, assurance of cooperation between relevant authorities and citizens, basic technical analysis and steps to be followed, evaluation criteria of proposed measures and assurance of targets and vision success were analytically described. They will have the form of a National regulation and after a one and a half year of implementation, they were finalized, signed by each participating member and are going to be provided to the 152 Municipalities for starting their SUMPs. Some remaining issues to be solved include the organizational reformation of the Ministry of Transport in order to create a quality control committee who will make the final check of the SUMPs that will be developed by the Municipalities.
