The Transport Committee has responded to information released
  today by the Office for Rail and Road highlighting shortcomings
  and missed targets in the technology used to detect broken-down
  vehicles on smart motorways.
  Chair of the Transport Committee  said:
  “The statistics revealed today by the Office for Rail and Road
  raise considerable concerns about the performance of National
  Highways in protecting drivers on smart motorways. This is
  putting lives at risk.
  “The idea that in some regions of the country less than 60% of
  stopped vehicles were detected on smart motorways is chilling. In
  addition the fact that, in some areas, it took over 60 seconds
  for a stopped vehicle to be detected is also deeply concerning.
  Every second counts when cars, coaches and lorries are driving at
  up to 70 mph and there’s no hard shoulder.
  “This Committee has been highlighting issues with smart motorways
  for a number of years, and we were supportive when the Department
  for Transport told us in January it was pausing the creation of
  new smart motorways, in response to the Committee’s
  report.
  “This new data will undermine trust that this system can work.
  “It is positive that National Highways has today come out and
  said it will invest in improving the Stopped Vehicle Detection
  Systems. The dangers, however, are real right now and I urge
  National Highways to show greater urgency than promising action
  ‘within the next six months’ given that the Government said
  nearly a year ago that it was spending £390 million on improving
  Stopped Vehicle Detection systems.”
