Almost half of fatal rear-end collisions at the tail end of a traffic jam

Almost half of the fatal rear-end collisions occur at the tail end of a traffic jam. This is mainly because at the tail end, the speed of the traffic flow decreases sharply, which coincides with frequent and hard braking. Extending congestion signalling and warning systems could prevent congestion-related crashes. At the moment, about 60% of the motorways in the Netherlands have this kind of signalling.
