API Documentation
This website presents the annual estimates of traffic on Great Britain’s roads. It provides figures for traffic broken down by vehicle type, road category and geographic area.
Road traffic statistics has an open API you can use to access the data without any authentication.
There are currently no rate limits.
The base URL for each endpoint is https://roadtraffic.dft.gov.uk/api/
Most of the endpoints return paginated results, which can be filtered on allowed names. See the API reference for more details about the different records and available filters.
