Road accident investigation using an object-oriented database Available to Purchase

The continuation of the downward trend in the number of injuries arising from road accidents in Britain and the effectiveness of casualty reduction targets are both dependent upon the availability of improved high-quality information. This paper describes the development of, and issues surrounding, an experimental road accident database within a geographical information system (GIS). It highlights ways in which the quality and completeness of road accident data may be improved by providing a separate definition of the road network and considers the benefits of using an object-oriented database system.
