§ The Marquess of Ailesbury
asked Her Majesty's Government:
Whether they will confirm that statistics relating to road traffic accidents are not kept in respect of every road junction in the country; and whether it therefore follows that statistics issued by local authorities, claiming to list in order the worst so-called blackspots, should be regarded with a degree of scepticism.430WA
§ Lord Brabazon of Tara
Personal injury accidents reported to the police do have their grid-reference and junction type (if any) recorded in the statistics. Casualty figures for individual junctions can be specifically built up over a number of years and, with other data such as traffic flows, this enables local authorities to identify priorities for remedial measures.
