Lineage



Accident data is derived from ‘personal injury road traffic accidents reported to the police’ part of a national dataset going back to 1980. Herts police provide HCC with automatic exports weekly. These files are downloaded and decoded. Record locations are cross checked using highways inventory information, and assessed to determine it passes all Stats 20 validations. Data is then loaded into our access database from where the spatial data is derived.
