abstract="In 1988, the casualty rate varied considerably in different places in England -- from 772 casualties per 100,000 population in Surrey, 30% above average, to 399 in Tyne and Wear, 33% below average. Casualty rates in some counties had decreased, whereas in others there had been increases. An analysis of casualty rate data for 46 counties in England shows that the casualty rates for different types of road user must be considered separately, as counties with a high casualty rate for one mode of travel may have a low casualty rate for other road users. Much of the reduction in the percentage of killed and seriously injured was probably due to the reduction in two-wheeled motor vehicle casualties. There is also some indication that increased congestion may have reduced the severity index in some counties.<p />",
