This function is based on anonymized communication of a driver’s position to the cloud. The telematics unit – a Bosch connectivity control unit (CCU) or an everyday smartphone – sends the required GPS data to the cloud only when the car approaches a highway on- or off-ramp. In the cloud, the vehicle path is compared with the permitted driving direction so that a warning of a deviation can be sent immediately.
The wrong-way driver warning is transmitted in a matter of seconds – not only to the driver in question, but also to other connected road users in the area. In addition, the warning is accompanied by response recommendations tailored to the given situation. Since smartphones have now become commonplace, the cloud-based wrong-way driver warning is a solution that offers more safety on the road virtually everywhere.
With current technologies, the average time between an incoming emergency call and broadcasting the traffic warning is 3.5 to 4 minutes.*
Mistakes that multiply
More than 2,000 alerts are sent out concerning wrong-way drivers on German highways every year. In most cases, the driver has gone the wrong way along a highway on- or off-ramp or performed an illegal turn. When wrong-way driving results in an accident, the consequences are often severe: for roughly every 80 accidents involving a wrong-way driver, half will result in personal injury and 20 in fatalities.*
Solution in sight
Even if we will never be able to fully prevent incidents of wrong-way driving, providing prompt information and orientation can help reduce the resulting danger. Bosch offers an innovative cloud-based wrong-way driver warning that provides pivotal support and covers key aspects of improving road safety.
