Based on a detailed definition of the product specification from the clients and operators point of view (AP1) and the technical options (AP2), a “Parking Management, Monitoring and Pricing System” (PAMMOS) will be developed, which automatically or partly automatically supports the management of parked vehicles along public streets and park & ride facilities. This includes the automatic accounting for the client with an on board unit, supporting enforcement with a portable control unit and the ability to detect and crossing up the current supply situation as input for transport management systems, transport guidance systems on city level or individual navigation systems for clients. The implementation of such a system will use the Global Positioning System (GPS) to be able to localise the parked vehicle and determine the duration of stay. A specific characteristic of the proposed system is the independency of hardware infrastructure below the street surface (e. g. sensors for vehicle detection). By comparing these data with the actual parking fee regimentation, these fees can be accounted automatically and cashless with the client. For such a prototype within this project all necessary hardware (AP3) and software (AP4) will be developed followed by a function test (AP5) and an evaluation (AP6).
