SPECS at Roadworks

Most major roadworks schemes around the UK are controlled using SPECS average speed enforcement cameras.  Since 2000, over 350 of these temporary installations have been operated, improving site safety for contractors as well as smoothing traffic flows and reducing congestion.

JENOPTIK Traffic Solutions UK are the market leaders in roadworks enforcement solutions, having delivered successful schemes on every major motorway in England, Scotland and Wales.  Roadworks are by their very nature a hazardous environment, so the design and operation of the enforcement scheme is particularly important.  SPECS average speed cameras are used because they reduce the risk that high speed vehicles will enter the works zone, whilst also improving flow conditions despite the possible presence of narrow lanes, construction vehicles and temporary road surfaces.

Data from SPECS controlled schemes shows that vehicles travel through the works at a steady, uniform speed.  By removing speed variability between the fastest and slowest vehicles, the occurrence of sudden ‘shock wave’ braking is largely eliminated.  This means that collisions are less likely, but traffic also flows better, allowing journey reliability to be maintained.  Recent works on the M1 6a-10 motorway widening won a Prince Michael International Road Safety Award, where the roadworks were significantly safer than the motorway had been previously.

Why are SPECS average speed cameras used in roadworks?:

  • Fewer injury collisions occur in SPECS controlled works

  • Construction workers feel safer whilst working close to the live carriageway

  • Journey reliability is improved

  • Congestion through the works and around junctions is reduced

  • 85th%ile speeds are consistently just below the posted 50mph limit

  • Compliance is seen through the works zone, not just at camera locations

  • Typically, only 1 in 10,000 vehicle journeys results in a ticket
