In October 1997, the Swedish parliament adopted Vision Zero as a new long term goal and strategy for safety. It is twenty years since this historical decision was made and in this talk both Swedish and global experience how Vision Zero has affected both safety operations, safety technology and interventions and finally the effects of all this will be presented and discussed. Now we can clearly say that it is possible to construct safe systems to support people in the traffic. To ensure safe mobility for all road users, a few innovations have been implemented, such as safe pedestrian, cycle and moped crossings in urban areas, and 2+1-lane roads The primary objective of the Vision Zero in relation to the behaviour of road users, is to help and support them comply with key traffic rules. Such an approach takes it starting point in their capabilities and limitations. But we need to have a balanced expectation on what can be achieved with regard to human behaviour with traditional behavioural shaping measures and acknowledge the possibilities of technical development. Further, the behaviour of organizations is also important in supporting their individuals to act safely. In October 2016, the Swedish Government renewed its commitment to Vision Zero.
