  • Cameras have a proven effectiveness in cutting speeding and RTIs.

  • On average, the number of killed and seriously injured fell by around 50 per cent at fixed sites, and by around 35 per cent at mobile sites.

  • The number of vehicles exceeding the speed limited fell by 70 per cent at fixed camera sites.
