This report describes the development and testing of an accident analysis methodology with particular concern for the accident problems of cyclists. A comprehensive review of the literature concerning accident analysis and the provision of cycle facilities was made and is published as a separate document. From this review and the methods used in five selected local authorities a cycle accident analysis methodology was developed. Important features of the methodology are that separate consideration is given to the accident problems of cyclists, and that remedial schemes should be selected so as to give expected casualty reductions by road user type approximately in proportion to the level of casualties of each type. The methodology was tested by its application to the accident data for Portsmouth for the three years 1984-1986, and was successful in clearly identifying the worst accident locations for cyclists and enabling dominant accident types and feasible remedial measures to be established.
