Stredar is a low-cost, community-owned Speed Indicator Device. It measures vehicle speeds, gives drivers real-time feedback, and feeds anonymised data into a national picture of road safety across the UK.

The Device
How Stredar Works
01
Speed is measured
A Doppler radar module detects approaching and receding vehicles and calculates speed in real time.
02
Drivers see their speed
The LED display shows the vehicle speed as it passes — immediate, visible feedback. No cameras. No prosecution.
03
Data feeds the national picture
Anonymised readings are uploaded automatically and appear on this platform, building a transparent record of road safety conditions across the UK.
Current Status
Pilot in Progress — Norfolk
The first Stredar unit is in development. We are seeking formal approval in principle from Norfolk County Council to site the pilot on Station Road, Holme Hale — a rural road where community concern about vehicle speeds is well documented.
Norfolk County Council has been briefed at leader level. Field testing is expected to begin later this year. The data from this pilot will inform the national rollout.

Evidence-led road safety without the procurement burden
Stredar units generate the same anonymised speed data as expensive commercial SIDs — at a fraction of the cost. Designed to complement, not replace, your existing road safety toolkit.
