Surrey now surveys speed at 1,000+ sites using Connected Vehicle data

London - 6th October 2026

FOR IMMEDIATE RELEASE

‍Surrey County Council is measuring 1,339 sites as part of its Speed Management Plan using Connected Vehicle data instead of radars and automatic traffic counters (ATCs). This new approach allows the council to run the survey on demand, saving thousands of pounds. 

Using Connected Vehicle data provided by Compass IoT, Surrey has removed the physical constraint of installing hardware, retrieving it and processing the data. Previously, that process could take up to three weeks per site and cost £500 to £1,500, limiting how often Surrey could assess speeds and act on what they found.

Now, rather than deploying hardware site by site, Surrey supplies the coordinates of each survey location, which AI converts into a mapped road segment. Speeds from vehicles that have already travelled on the route provide the average and 85th percentile speed. These vehicle speeds are taken across the full road segment rather than a single point, capturing driver variations. 

“Now we don't need to wait weeks to get speeds for our roads. This new dataset is available instantly, and replaces the need for traditional speed surveys; it allows us to make faster and more informed decisions”, said Matt Walsh, Speed Management and Camera Enforcement Team Leader at Surrey County Council.

Before committing to the new data source, Surrey tested it against the survey methods it already used. The council found that speeds from Connected Vehicles aligned with ATC speeds and were more accurate than those recorded by radar.

The practical effect is a shift from snapshot to monitoring. A yearly survey with hardware shows what was happening on the days the equipment is out; a recurring survey from the Connected Vehicle data source shows how speeds change over a month, and gives a more accurate before-and-after when something changes. 

Using this data, Surrey and other councils gain a complete picture of how vehicles are behaving across their roads. Rather than dispatching crews to install radars and ATCs, engineers can get speed data and action treatments sooner if required.

The same approach is available to other councils across the UK. To learn more, Compass is hosting a National User Group on 10th November. This exclusive event will connect transport professionals across the UK, sharing new insights from road authorities that could lead to a better and safer road network. Register your interest here.
