A major part of the surveillance effort for the urban transportation planning process in the Quad City Area involves the collection of data on traffic accidents occurring at major street and highway intersections. Accident information is an important factor from which to work towards the regional Transportation System Management objective of improving the safety of the local transportation system. Accident surveillance provides a source of information through which state and local officials may examine and respond to the changing traffic conditions of the existing street and highway network. It will also raise the awareness of drivers when traveling and the attention of police officers when patrolling. For these reasons, Bi-State Regional Commission has compiled this study report which examines the traffic safety performance of street and highway intersections in the Quad City Area in 1993. The Quad City Intersection Traffic Accident Study for 1993 is the fourteenth such report prepared by the Bi-State Regional Commission. This year's report provides an analysis for intersections with seven or more accidents per location. For the ten highest ranked intersections in each state, collision diagrams were presented. In addition, the five-year accident history data is summarized for these intersections.
