What councils look for.

Highway authorities ask for the collision record around a site in most Transport Statements and Assessments, usually for the latest five years. They look for patterns: several collisions at the same junction, at the same time of day, or involving people walking or cycling, that a new access or extra traffic could make worse.

The map shows injury collisions reported to the police, from the Department for Transport’s published data for Great Britain. Collisions with no injuries are not recorded here. Where there is a cluster, the police records held by the highway authority give the detail of how each collision happened.
