Cloud-based wrong-way driver warning

Operation principle of the cloud-based wrong-way driver warning

If a vehicle approaches a highway entrance ramp or exit ramp, the system automatically sends the anonymized data of the current movement to the cloud. The function compares the vehicle’s actual movements with the permitted direction of travel. Information about this is stored in a web-based database. If the two sets of information clash, the wrong-way driver automatically receives a warning. At the same time, the cloud immediately transmits a warning to all networked road users within the danger area. When leaving the highway entrance ramp the communication with the cloud is interrupted again.

The function relies on regular, anonymized reporting of each vehicle’s position to the cloud – a central computer center in which data are stored and analyzed over the internet.
