In the Ko-TAG joint project, vehicle-mounted transmitter-receivers exchange data by radio with active, RFID-like elements (in the following referred to as tags or transponders) carried by other road users, e.g. integrated in school bags, helmets or mobile phones. These tags can be located, clearly classified and tracked anonymously.
With the data obtained from the tracking of detected objects, such as direction of movement, distance and speed, the situation can be evaluated comprehensively and – in combination with suitable movement profiles – the collision risk can be assessed precisely. The calculated risk forms the basis of warning and triggering algorithms and for the initiation of suitable preventive measures (e.g. automatic braking).
This cooperative sensor technology can even locate and clearly classify road users who are invisible to the driver at the moment of danger.
The researchers are especially interested in how this technology can be used in broader scenarios involving numerous parties. They are thus developing strategies to merge the information from vehicle and localisation data, and to use the results in order to give the driver active support in terms of safety and to assist him/her in critical situations.
