Speed Indicator devices (SID) measure the speed of approaching vehicles and display the measured speed and a smiley or frowning face. SID are not intended to directly enforce speed limits, but rather to inform motorists and modify their driving behaviour, either when approaching a danger zone or to generally comply with the speed limit. Because it flashes up vehicle speed, a message and either a smiling or frowning face, the SID is an excellent awareness raising tool and is particularly effective at targeting drivers whose speed has crept up due to lack of attention or awareness of their surroundings. Allowing drivers to see their current speed enables them to correct it or reduce it to a more acceptable level.  We also have temporary correx street lighting placards created by Bucklebury Primary School that are used as part of the awareness scheme. 

Details of the Speed Indicator Device (SID) operation and reports

• Operating Instructions
• Useful Links incl Crashmap data

Due to the volume of data we have moved from using the manufacturers software to create individual reports to our own Excel spreadsheet that allows us to analyse each site and provide Bucklebury Parish Council, West Berks Council and Thames Valley Police with a summary of the situation. Over 250,000 vehicles were recorded in 2023 and the results summarised below. 2024 summary data will be attached below and periodically updated. Earlier format reports are linked below to graphically illustrate the output from SID:

• July 2023 Reports

• August 2020 reports
• November 2019 Reports
