Trevi Park - Automatic Parking System

Garage incorporated as foundation of an apartment building

The Need

TreviPark is an underground, multi-story stacking system that holds cars efficiently, thus reducing the cost of each parking space, as a fully automatic parking system intended to maximize space utilization in parking structures. TreviPark costs less than the price of a conventional urban garage and takes up half the volume and 80% of the depth. Using a silo structure, preferably underground but possibly in elevation, the system provides automatic parking of vehicles with a controlled and secure deposit and retrieval area. Drivers leave their cars in a parking lane that serves as a loading-pick up point, and vehicles are automatically transported to a parking bay. The circular design offers the engineering efficiency of unbraced constructions, with associated shorter construction time and lower costs than rectangular structures. Since the vehicle is not running when being stored, TreviPark uses only one third of energy required to ventilate a conventional garage.

The Technology

TreviPark is applicable in dense urban areas or in special circumstances which limit parking on grade or in elevation. The system reportedly reduces the cost of each parking space by holding cars efficiently; the use of vertical elevators rather than ramps and driving lanes permits optimum storage capacity and reduces land needs. Heating, air circulation, and lighting costs are minimized, as all patron activity is above ground in the service.

TreviPark fits into a 72'-diameter circle and holds 12 cars per floor, accommodating between 72 and 108 cars, with a surface impact of only two parking spaces and one kiosk. A surface kiosk, which provide a sheltered and secure waiting area during retrieval, is designed to enhance surrounding architecture and open space. Retail or other public services can be incorporated into the design of the kiosk. Parking takes place automatically, without the driver on board. The patron simply drives the car into a parking lane that serves as the loading pick-up point, turns the car off and leaves. The car is then conveyed into the cylindrical structure by an elevator that automatically transfer the car to a safe dock. The driver receives a magnetic card to retrieve the vehicle and to pay for its storage. Total cycle time for retrieval takes between fifteen seconds and one minute, based on vehicle location within the circular garage.

The Benefits


At the present time Trevi Icos Corporation have four parking systems in operation; two in Cesena, one in Milan and one in Rome, all in Italy and also have three under construction in Italy and two under contract in Belgium and England.


Initial cost is relatively higher than traditinal parking system, but the cost can be offset by lower operating costs.
