Although GNSS often is seen as the ideal means to gather data for toll collection over a wide area, much still needs to be discovered around the real suitability. A number of trials have been conducted worldwide utilizingGPS navigation with varying results until now. Real implementations have been limited to a Highway-only approach (Germany) or the utilization of GPS to verify tachometer data (Switzerland). The implementation of a nation wide tolling scheme capable of charging any kilometer driven is faced withcompletely different constraints. Accurate and reliable GNSS positioning data is absolutely required for the primary process of fee calculation andmap matching is degraded to a helpful secondary process. Numerous OBU (on-board unit) volumes resulting from nation wide implementations, force to implement far-reaching measures to reduce cost connected to vehicle related equipment. It cannot be excluded yet that design choices will have to bemade that threat interoperability but are necessary to make implementation feasible. LogicaCMG has been and is conducting studies into the feasibility and the do's and don'ts of such nationwide tolling schemes. For the covering abstract see ITRD E134653.
