Communication & Standards

Considering recent developments, future traffic system interlinks will need to operate with different communication and protocol standards according to the use case. The systems will also be designed to allocate roles to institutions in a flexible manner. The classical strict distinction between “private” service providers and “public” infrastructure operators is not required from a technological point of view. The public sector can transmit data to vehicles and mobile devices, or the private sector can provide services to public infrastructure operators.

In view of this situation, the UR:BAN applications will support current efforts toward standardization and comprehensive ITS system architecture. The applications in the sub-projects “Smart Intersection” and “Urban Roads” will support both short-range (IEEE 802.11p) and mobile (e.g., UMTS) car-to-infrastructure (C2I) communication standards. Data can be pre-processed by a service provider as in the sub-project “Smart Intersection” or directly provided by the city (sub-project “Regional Network”). The system architecture will into account specifications developed in the Car2X consortium, which runs in parallel to UR:BAN.
