VAS data


Recent results from the Clare speed sign

The key facts are:

  • The A1092 in Clare typically has about 3,000 vehicles per day each way, e.g. that is 6,000 in both directions, with a peak flow at busy hours of about 400/hr each way, or 800/hr in both directions.
  • About 75% of drivers on average exceed the 30 mph speed limit, with 25% in excess of the ACPO speed of 35 mph.
  • Dangerous speeds of over 50 mph are recorded nearly every day before 8 am in the morning and after 8 pm at night, when traffic density is low.
  • During the hours when most retired drivers are on the roads, 10 am to 3 pm, speeds are at their lowest and very few drivers exceed 35 mph.
  • This data is passed to Suffolk Constabulary who will then deploy a mobile radar speed trap – without notice – to control speeding motorists.
