Vehicle/pedestrian anti-collision system

One of the major risks on a construction site is the coactivity of pedestrians and machinery. Vehicle/pedestrian collisions represent 2000 accidents per year. CAD.42 has developed KYD.42 to avoid the risk of accidents.

Principle of operation

KYD.42 measures its distance with the other beacons and alerts the driver and the pedestrian with an audible signal, a vibration, and a light flash when a predetermined limit is crossed with at least one of them. This limit can be set using a single smartphone or tablet.

Each beacon can have its own alert distance.

One or more KYD.42 are magnetized on the machine. Pedestrians who can work nearby are equipped with a KYD.42 with armband or support for installation on a helmet.
