Parish Speed Indicator Device Scheme

What is SID? SID is a battery/solar operated radar device that detects speed of vehicles up to 150m from its position. It indicates speed of vehicles travelling towards the sign with an appropriate message to the drivers. It also detects the speed of vehicles travelling the opposite direction away from the sign.

What is recorded by SID? It records the volume of the vehicles passing the sign in either direction at set intervals, the average and maximum speed of the vehicles and the date & time.

What message does the SID display? SID displays a “THANK YOU” message in green to drivers who conform to the speed limit and a “SLOW DOWN” message in red to those drivers travelling too fast. For vehicles travelling more than 30mph the sign will flash a red triangle and a slow down message but will not display the actual speed, this is designed as an “anti-racing” measure.

How many and where are the SID Locations? We have bought 3 devices and they are situated where SCC Highways Team advised they be used.

  1. B1115 by Allotments & Devon Road in a 30mph area
  2. A1120 by Village Hall on Church Road in a 30mph area
  3. Thorney Green Road in a 30mph area

What has been the experience of SID so far? We believe this has slowed the traffic within those areas, and we have received good comments from parishioners. The data will be downloaded quarterly and published on our website for everyone to read, it will also be sent to Suffolk Police for monitoring.

How can I help with SID? SID is managed by the Parish Council and relies on volunteers to assist with turning each device, switching off the device for the required amount of time, collecting the data and reporting the data to police. It you would like to be involved in this process please contact the Parish Clerk ( parishclerk@stowuplandpc.co.uk )
