Road safety

Collision data and STATS19 analysis.

Collision analysis using STATS19 personal injury data, explained clearly so the council and the committee can see what the record actually shows.

Also known as: collision data, STATS19, accident data, personal injury collision data, PIC data

What we do

What’s included.

STATS19 is the national record of personal injury collisions reported to the police. Highway officers use it to judge whether a scheme raises safety concerns. We obtain the data, map it and explain any patterns honestly.

  • Data requests from the council or published sources
  • Study area agreed with the officer
  • Mapping and severity analysis
  • Contributory factors and patterns
  • Vulnerable road user collisions
  • Conclusions tied to the scheme
How we approach it

Straightforward, proportionate, agreed early.

The right data

The most recent full years, for the area the officer cares about.

Clear maps

Collisions plotted and grouped so patterns are easy to see.

Honest conclusions

If there is a problem the scheme could worsen, we say so and propose a fix.

FAQ

Questions we get asked

Where does STATS19 data come from?

From police reports of injury collisions, published by the Department for Transport. Councils can also supply local extracts.

Does STATS19 include damage-only collisions?

No. It covers collisions involving personal injury that were reported to the police.

Is a high number of collisions a reason to refuse?

Not on its own. The question is whether the scheme would make highway safety unacceptably worse.

Using collision data properly

STATS19 is the national record of personal injury collisions reported to the police. It does not include damage-only collisions, and it records the circumstances reported at the time, so it needs careful reading.

Highway authorities usually ask for the latest three or five years. The question is whether there is a pattern the development could make worse, not simply how many collisions there were.

  • Collisions mapped and grouped by location, type and cause.
  • Patterns checked against the layout, speeds and lighting.
  • A clear view on whether the scheme would affect safety, and what would help if it would.
