These plans predict  single groups of interventions and give, for each proposed intervention, the definitive dimensioning, including the circulation schemes.

They must develop therefore:

• projects for pedestrian structures (sidewalks, pedestrian crossing with related protections)

•  the organization of public transport stops and terminuses,  as well as the interchange parking areas;

• detailed circulation schemes for the different itineraries of the main roading, with the solutions proposed for the reorganization of crossings, both free and traffic lights regulated;

 the organization of parking places, both along the main streets and in the parking streets, as well as the possible parking lots outside the street network, multi-storey or undergound.
In particular, the Municipality of Milan, while formulating the invitation to tender for services related to the drawing up of the detailed plans, has identified the following main objectives, according to the strategic guidelines stated by the PGTU:

• improvement of the pedestrian circulation, also through the re-calibration of sidewalks and the identification of  pedestrian passes and crosswalks;

• preservation vehicular fluidity near the possible Pedestrian Areas (AP), Restricted Traffic Zones (ZTL) and Environmental Isles (IA)

• new circulating and parking disciplines in commercial or recreative areas

• solving nodes and paths critical for the continuity of cycling network

• reorganization and the possible relocation of public transport stops, terminuses in order to improve the safety conditions for the passengers

• improvement of public transport circulation, also through the individuation of possible reserved lanes

• building a detailed scheme for vehicular circulation, according to the different hierarchical levels of the streets;

• individuation of parking lots, related to the realization of pedestrian areas, to the improvement of the environmental quality of the quarters, to the new regulation for parking along the main streets, to the parking demand by residents and other subjects interested (commuters, shopkeepers, artisans, customers etc.);

• improving the crossings of the main streets, through the regulation of priorities, new junction scheme (also multileveled) and the installation or reorganization of the traffic lights system.

• the increase of the road safety, through the analysis of the accidents on the road network and the drawing up of projects aimed to the safety of critical itineraries and nodes.

In order to achieve those objectives, the study of the more effective strategies and project options could only pass through a careful readout of the existing data, integrated with surveys focused on circulation (of vehicles, cycles and pedestrians), on parking demand, on traffic devices.

This surveys will allow to have a more and more accurate real “photography” of the existing situation and will increase the Data Bank of the Agency, with all the information necessary to deal with urban and suburban traffic planning with a rational and concrete modellistic approach.
