Tailoring a Reference Model for C‐ITS Architectures and Using a DATEX II Profile to Communicate Traffic Signal Information
Jörg Freudenstein, Ian Cornwell · Traffic management · 2016
This chapter shows one example of how to tailor a generic Cooperative-Intelligent Transport Systems (C-ITS) architecture developed in the SEAMLESS project to the needs of the use case Traffic Light Phase Assistant and gives a profile at hand for a DATEX II communication. DATEX II is the European open, interoperable interface specification for machine to machine communication of dynamic transport and travel time data between centrals and with third parties. It is based upon well-accepted IT standards such as UML. For the communication channel, a DATEX II profile has been developed and published to exchange traffic signal data between a central and a service provider. The SEAMLESS project shows that there is a lack of clarity on the role of the Roadside-ITS-stations (R-ITS-S) - the number of possible R-ITS-S scenarios is as huge as the number of different tasks for the ITS communication.
