Permanent SPECS

SPECS is the world leading average speed enforcement system, using networked cameras to cover a length or area of road.


SPECS cameras have been used in the UK to control speeds at accident hotspots and major roadworks since 1999. SPECS can be used on virtually any public road, from a 20mph urban street to a high speed, multi-lane motorway. Cameras can be configured for a variety of links, covering hundreds of metres or tens of kilometres, with the capability to monitor vehicles entering and leaving the speed control zone in different lanes.

Jenoptik introduced a further development of this technology in the shape of SPECS3, which received Home Office Type Approval (HOTA) in 2009, bringing the benefits of SPECS to an even greater range of applications.

SPECS3 VECTOR is the very latest HOTA version of this solution, using integrated cameras that significantly reduce installation costs, achieving approval in July 2014.

More than 130 permanent SPECS installations have been contracted around the UK, delivering significant benefits in terms of casualty reduction, improved traffic flows, all whilst achieving public acceptability.A fantastic example of this is the scheme along the A9 in Scotland. This enforcement scheme is the longest in Europe, with SPECS covering 220 kilometres of the A9. Delivering a first year KSI reduction of 64%, combined with 70% of road users feeling safer, the A9 scheme demonstrates how innovative ITS technologies can rapidly address long-term strategic problems and local community concerns.


  • Killed or seriously injured figures typically drop by >70%
  • Journey reliability is improved
  • Congestion through the works and around junctions is reduced
  • 85th%ile speeds are consistently just below the posted speed limit
  • Compliance is seen through the works zone, not just the camera locations
  • Typically, only 1 in 10,000 vehicle journeys results in a ticket
