The Sustainable Urban Mobility Plan (PUMS) is the strategic document that aims to guide city mobility policies for the next 10 years. Among the specific strategies adopted in the PUMS project scenario in order to achieve the objectives and priorities recognized by citizens and Stakeholders, there is a hierarchically structured system of Mobility Centers that take the form of multimodal hubs to support the concept of Mobility as a flexible service that can be planned by users (MaaS). Hubs can be created in correspondence with existing or project nodes, where specific conditions or opportunities require it. In the Hubs, the presence of activities and services aimed at making the waiting times associated with the interchange perceived as an opportunity rather than a cost. The preparation of the PUMS is based on a scenario logic, aimed at verifying and comparing the effects of different possible strategies for managing mobility: the Reference Scenario (i.e. the interventions that can be implemented independently of the PUMS as they are already planned-programmed and already provided with financial backing), the Plan Scenario (i.e. the infrastructural and non-infrastructural interventions, additional to reference scenario that meet the general and specific objectives set by the PUMS), the evolutionary scenario. The PUMS geographical data being published refer to the three scenarios of the plan contained in the approved tables. 121 of 19 December 2018 and with Resolution of the Metropolitan Council n. 24 of 04/21/2021 definitively approved the Pums-Urban plan for sustainable mobility of the Metrocittà.
