This book evaluates the ability of ad-hoc and cellular communication to enable cross-traffic
assistance at intersections. Potential issues like Non-Line-Of-Sight (NLOS) reception with
ad-hoc and limited capacity higher latency and costs with cellular technology are investigated
in two individual evaluations. A method for efficient information delivery via cellular systems
and an inter-vehicle NLOS radio propagation model are proposed. Finally the suitability of
both technologies is compared.
