Police Enforcement and Road Accident Reduction

In this paper we report on the analysis of a database created by merging Road Traffic Accident information and police enforcement data relating to forty two Police Force Areas in England and Wales. The enforcement measures available to the police range from Prosecutions to Fixed Penalty Notices, Written Warnings and Vehicle Defect Rectification Notices. The investigation was structured to identify any correlations between the enforcement actions and the level of road traffic accidents, the rate of killed and seriously injured and the overall accident severity rate. Accident data was derived from the UK Road Traffic Accident dataset, STATS19 returns, and enforcement data obtained from the UK Home Office. The STATS19 returns detail every road traffic accident involving personal injury, reported to police, and the Home Office data supplies information on the number of Prosecutions, Fixed Penalty Notices, Written Warnings and Vehicle Defect Rectification Notices issued. Annual time series data was available from 1991 to 2003 and quarterly data from 1999 to 2003. The database also included variables relating to population size, road, traffic, and socio-demographic characteristics. Multiple regression models, developed from the database, supply tentative evidence that an increase in levels of enforcement, as measured by Vehicle Defect Rectification Notices and Fixed Penalty Notices, results in a reduction in the rates of killed and seriously injured. Memory effects were considered by using time lags of one quarter, two quarters and one year. Results suggest that the effect of increased levels of enforcement are not always immediately apparent but are often manifest three to six months later.
