Applications of microwaves and millimeterwaves for vehicle communications and control in Europe

The author discusses the broad scope of ongoing work in Europe in the area of vehicle communication and control. The solution to traffic congestion and increasing pollution lies in the application of advanced technologies to control and direct the flow of vehicles. Pan-European projects like PROMETHEUS or DRIVE are supporting such solutions. Four major areas of applications are distinguished: automatic debiting systems (ADS), road traffic informatics (RTI), microwave Doppler sensors (MDS), and collision avoidance radar. Millimeter-wave systems have found an increasing interest, due to their specific advantages, as well as the lack of frequencies available for new services. The four application areas are described.<
