Community Speed Watch

Community Speed Watch is a traffic monitoring scheme, supported by partners within SERP.  It is delivered in communities by dedicated volunteers who feel passionately about road safety in their area.

Community Speed Watch Volunteers monitor the speed of passing vehicles using a hand-held speed detection device.

The volunteers record the details of vehicles which are exceeding the speed limit by around 10%. These details are passed to the Police, who will issue a letter to the vehicle owner, advising them of the dangers of speeding, and reminding them of the law. Essex Police also use the intelligence provided by volunteers to highlight those communities that would benefit from additional police enforcement, based on evidence of poor levels of compliance. This additional enforcement is primarily conducted by officers from the Casualty Reduction Section including its own team of Special Constables.

All volunteers are required to attend quality assured training provided by SERP, comprising a presentation followed by a roadside activity.

All volunteers are required to wear hi-vis jackets and display signs approximately 100 meters (at a safe pre-assessed site) either side of the monitoring location.

The benefits of Community Speed Watch include:

  • The opportunity for residents to increase road safety in their area, and support activities to reduce road traffic collisions and injuries.
  • Enhancing the role of community members as volunteers and developing better links with the community.
  • As Community Speed Watch volunteers are highly visible and make use of a speed detection device, it is usually clear to vehicle drivers their speed is being monitored. This may be enough deterrent for many motorists to slow down.
  • The ‘community’ element of Community Speed Watch could have a more positive effect on some vehicle driver’s attitudes compared to engineering schemes.
  • The letters vehicle drivers receive as a result of exceeding the speed limit may make them continue to reduce their speeds at all times.
