Highway Accident Collision Diagrams on a Microcomputerby Thomas L. Maleck, Michigan State Univ, East Lansing, MI, USA,
Abstract: Collision diagrams of highway accidents are schematic exhibits that illustrate the location of each accident with respect to the highway geometric features. The types of accidents; such as, rear-end, right-angle, left-turn, etc. , are also illustrated. The severity of the accident (fatal, injury, or property-damage), object-hit, direction-of-travel and other related information is often provided. The end product is a graphic description of all accidents having occurred during a specific time period. Collision diagrams are used by the engineer to identify accident patterns or trends that may be diminished or prevented by operational and/or geometric revisions to the highway. The diagrams may be used during office reviews or field investigations. They are also used as exhibits at public hearings and in published reports.
