Available road accident statistics over many years show that many accidents are related to the field of human factors. Driver assist systems, such as the aforementioned FCW, AEB, LDW and LKA, as well as night vision, adaptive lighting, detection of vulnerable road users and blind spot detection, all have a substantial potential to improve drivers’ performance and should be promoted further. Driver state monitoring including drowsiness and distraction detection is developing quickly and has, in particular combined with the other driver assist systems, also a large life-saving and injury reducing potential and should therefore be supported.
Although many accidents are caused by human error, some accidents are caused by wild animals, tyre bursts and the like. They are not frequent, but often result in severe consequences. Most driver assist systems aim to alert the driver about a particular situation. Night vision and adaptive lighting, for example, support detection of pedestrians and animals on country roads and reduce the number of this type of accident. Burst tyres are most often preceded by low tyre pressure, which is detected by tyre pressure monitoring systems (TPMS). CLEPA supports an extension of the TPMS regulation to light and heavy commercial vehicles.
As a way of supporting traffic rules compliance, safety-belt reminders have already proven to be highly effective, showing a decrease of 80% of the unbelted rate . However they have only become mandatory for the driver seat in European vehicles, inclusion of other seating positions should be considered. The deployment of speed assist devices (by ITS applications or camera-based systems) and vehicle integrated alcohol detection systems should be further supported. It is estimated that 5000 lives would be saved annually in the EU if alcohol limits were respected . The importance of keeping posted speed limits is a long-standing and well-recognised safety aspect.
