Road transport by car has become much safer today than it used to be in past decades. International car producers invest a lot of money and brainpower of their experts into increasing the road safery of their products, PSA group for instance uses about 150 millions euros each year for this purpose, concentrating on three interrelated fields:
- the understanding of the drivers behaviour and the improvement of his perception and control
- the enhancement of the road performance of the vehicle and
- the protection of the vehicle occupants in the case of an accident.
But due to the steady increase in the number of cars in use worldwide, still around 700.000 people die each year in road accidents.
One reason for fatal crashes can the lack of sight when driving at night. In France for instance 1/3 of all accidents happen during nighttime, even so only one fifth of traffic is happening during this time. Human beings cannot see in the dark, but infrared cameras can. PSA group developed "Night Vision" which uses computer-operated infrared technology which can alarm the driver in realtime when obstacles are on the road even at night, in fog or when the sun is shining directly towards the driver. The images are either put on a screen next to the steering wheel or projected directly onto the windscreen in front of the driver.
Look at the above demonstration.
