This paper proposes a new system to collect tolls
on open road tolling (ORT) infrastructures. The actual
Electronic Toll Collection (ETC) systems do not fulfill
fundamental user requirements, such as interoperability and
portability between systems and road operators (in the same or
different countries), as well as advanced toll logging and
reporting (capabilities ensuring user privacy, an interesting
feature in car rental or sharing use cases). The C2S is a work in
progress project that will provide some features, such flexible
payment options, recording of incurred tolls and make them
available to the end user and management entities, exploring a
synergy of technologies in ETC scenario, namely Dedicated Short
Range Communication (DSRC), Global Navigation Satellite
System (GNSS), Near Field Communication (NFC) and
smartphone-based mobile applications. This system is also an
approach to interoperable European ETC solutions, in a way
that uses DSRC and GNSS-based solutions together.
