Smart transport

The demand for transport of people and goods is continuously increasing. To make transport safer, more efficient and cleaner, various traffic telematics services are currently under development. Such intelligent transport systems (ITS) services require dependable vehicular communications (DVC) providing robust connectivity at moderate data rates. DVC includes vehicle-to-infrastructure (V2I), vehicle-tovehicle (V2V), wireless-intra-vehicle (WIV), as well as infrastructure-to-infrastructure (I2I) communication scenarios. We aim at the reliable transmission of small data packets with a hard delivery deadline. Achieving this goal will enable sensor data fusion among road users and the roadside infrastructure. Our aim is to enable cooperative ITS by DVC.

Our research activities in this area include radio propagation channel measurements and modeling and novel PHY transceiver algorithms development. We focus on WIV and V2V for on-board sensor networks, vehicle localization and tracking, as well as radio frequency and free space optical I2I communication. Dependability will be achieved by exploiting innovative diversity mechanisms in the (unreliable) propagation channel, jointly in the spatial-, polarization-, and frequency-domains, leaving out the delay-domain. Our research activities will include channel analysis, new algorithms development and PHY layer design.
