Choose a starting location
A full postcode is converted to its approximate centre using Postcodes.io. If you choose “Use my location”, your browser supplies coordinates after asking permission. You can also select a count marker directly.

Find nearby DfT points
The site calculates straight-line distance to traffic-count locations. Results begin within five miles and are sorted nearest first. You can increase the radius.

Load only nearby detail
National coordinates are compact, while full history and vehicle detail are split into 0.25-degree spatial shards. A typical search loads only the small files around the selected location.

Explain the estimate
Each result keeps its DfT method, year and most recent counted year where it can be identified. The full detail view shows trends, composition and comparison with the same road type.
Why the nearest point may not be on your road
DfT supplies an estimate for every major-road link in Great Britain, but only samples some minor roads. A nearby residential street may have no count point. The map and result list therefore show the exact count location and its distance rather than attaching another road's number to your address.
What the result does not say
It does not describe current congestion, traffic at a particular hour, noise, air quality, road safety, or the number of vehicles that stop locally. It is an annual average.
