In 1997, the Swedish Parliament adopted the "Vision Zero" road safety initiative. The long-term objective of Vision Zero is that no one shall be killed or seriously injured in traffic. To achieve this, it is essential for roads, and the vehicles they carry, to be adapted to match the capabilities of the people that use them.
Central barriers and traffic cameras are examples of innovations that have increased safety levels on Swedish roads, while older solutions such as roundabouts and alcolocks have been developed and have acquired greater importance since Vision Zero was established.
Since Vision Zero was introduced, the number of fatalities and severely injured in traffic has decreased by 30-40%. The number of mildly injured has also decreased. This is despite an increase in traffic.
