Italy is a unitary parliamentary republic and covers an area of 301,230 km2 (116,310 sq mi), with a population of about 60 million. All municipalities with more than 100,000 inhabitants must have their own integrated SUMP. Starting from January 2023, the adoption of a SUMP is mandatory in order to access funding related to public transport and the promotion of cycling programmes. A “Vademecum" (handbook) has been published, containing operational guidelines for the preparation of the SUMP.
