With the Communication, Localisation and Surveillance (CLS) technology, moving road users can be detected by transmitting V2X radio signals at intersections. The concept behind it is called Wireless Sensing and is based on the propagation properties of radio waves, which are reflected and scattered by objects. The CLS technology records baseband data (pulse responses) at four receiving antennas.
As part of the VIDETEC project, the CLS system was installed at a test intersection and a first dataset was collected for the recording of road users. Parallel reference systems (GNSS-RTK and laser scanners) document the data collection and allow validation and preprocessing for later use of the data set. The baseband raw data in various configurations and traffic scenarios were measured when using the CLS system at the test crossing.
