According to statistics, fatal accidents on the European road network have dropped by about 20 percent since 2001. The EU target is to halve this figure by 2010. One way of reducing risks in traffic is to integrate accident-preventive active safety systems into the vehicles themselves. Coinciding with the EU's Road Safety Day on April 27, Volvo Trucks is introducing two safety systems, Lane Keeping Support (LKS) and Adaptive Cruise Control (ACC). The LKS system, which is activated when the vehicle reaches 60 km/h, continuously monitors the lane-marker lines and alerts the driver via an audible signal if the truck accidentally starts wandering from its current lane. The new generation ACC system, instead, uses a radar unit linked to the engine and brakes to maintain a set safety gap between the truck and the vehicle in front.
