Sustainable Urban Mobility Plan


Naples, which extends over a limited quadrant of only 180 degrees, lies at the foot of a hilly system that makes east-west connections especially difficult. Naples’s mobility is an “ante-litteram” sustainable mobility: the first city to have a railway line (Naples-Portici), four existing funiculars, and now the new underground line (Line 1). The Naples SUMP is characterized as a short-medium (2025) and medium-long term (2030) strategic plan and contains accessibility strategies based on the completion of fixed-site networks. Travel is accompanied by an integrated multimodal offer (electric micromobility, shared mobility, hectometric systems, rail network and local public road transport) supported by tariff integration. The SUMP identifies a series of intermodal hubs for those who come from the Metropolitan City of Naples and make the first trip by car. Through the use of a complex multimodal model, the ambitious projections assumed as a target were verified (12% reduction in trips by car). The analysis of the mobility demand at the metropolitan level was carried out using innovative techniques based on the processing of the routes of telephone users (big data) in transit in the Metropolitan City of Naples. In terms of soft mobility, the SUMP proposes 12 new bike routes and 26 new 30 km/h zones and identifies new 20 bike-sharing stations. The municipal SUMP was adopted by the City Council in August 2021. The Metropolitan City SUMP is in the development process.


  • Surveys on public and private mobility
  • Construction of O/D matrices starting from the processing of telephone big data;
  • Implementation and development of a multimodal simulation macromodel;
  • Defining of the actions of the Plan, simulation and comparative evaluation of project scenarios by means of indicators;
  • Strategic Environmental Assessment (SEA) and Environmental Impact Assessment (EIA);
  • organization and management of public participation processes
