Traffic data sources

Primary live source: National Highways / Traffic England realtime road-event API.

TrafficTodayUK requests current congestion, incident and roadworks events by road number and converts the returned records into a consistent, searchable list. We acknowledge National Highways / Traffic England as the source and do not copy Traffic England maps or Ordnance Survey map tiles.

Coverage

The current live layer is centred on the Strategic Road Network in England: motorways and major A-roads managed by National Highways. It is not a complete feed for local streets, Scotland, Wales or Northern Ireland.

Official verification

For safety-critical decisions, always verify against official road signs and the relevant road authority. GOV.UK links to National Highways for live traffic on England’s major roads and to separate services for Scotland and Wales.
