Matching STATS19 collision data to a road network: feasibility www.gov.uk/government/s... report from DfT's statistics team Road Safety Data www.gov.uk/government/s... DfT's collision data is open … but OS NGD RoadLink isn't #roadsafety #transportdata #opendata #datapolicy

OS NGD RoadLink was selected for the feasibility study because DfT can access it through the Public Sector Geospatial Agreement, it provides detailed national road geometry and attributes, and it is related to the mapping used in the CRASH system used by many police forces to provide STATS19 data to DfT. In future, the road safety statistics team will agree the appropriate network product and version with the DfT roads geography team, taking account of the networks already used across road statistics, update timing, historic consistency and production support.

Because OS NGD is not an open dataset, the Department will confirm with OS which derived attributes, identifiers and aggregate outputs, if any, could be published or shared under licence. This will be explored further as the work progresses.

The Department for Transport has released final incident-level road safety data for 2025 www.gov.uk/government/s... (Great Britain) A long-running and very useful open dataset from DfT #STATS19 #roadsafety #transportdata #opendata

These files provide detailed data for road collisions in Great Britain from 1979, and the vehicles and casualties involved. The statistics relate only to personal injury collisions on public roads that are reported to the police, and subsequently recorded, using the STATS19 collision reporting system.

Final annual data is released annually in late July (brought forward from September) following the publication of the final annual reported road casualties Great Britain statistical publication. In addition, unvalidated provisional mid-year data (covering January to June) is released at the end November, to provide more up to date information.
