The subject of the project is a region-wide, integrated networking of intermodal transfer points (mobility points), which incorporates existing and planned municipal infrastructure and includes a holistic promotion of all offers of the environmental network. The concept is to be designed openly, so that the widest possible variety of providers and systems can be integrated. It will ensure a standardised interface for the use of the Stuttgart Service Card/polygoCard. The project includes four pilot implementations as well as the preparation of the region-wide roll-out.
