It has been known for some time that police records collected by the Department of Transport could be unreliable. Local Authorities use these data as an aid to the decision making process and to assist with objective setting. Studies warning of deficiencies in the accuracy of Stats 19 police data show confusing and often differing levels of inaccuracy. Due to the atypical nature of Road Traffic Accident typology the thesis sets out to examine a methodology for use by professional safety practitioners in order to test the reliability and accuracy of existing data and to test how in an operational environment these data might be expanded to meet the needs of the practitioner responsible for education, training and publicity measures rather than the pure highway engineering function.
