SAFETY/GIS MODELS REVIEWED AND RELATED TO LONG ISLAND ARTERIAL NEEDS STUDY

This paper describes the conceptual design and implementation of a geographic information system (GIS) safety application that was developed as part of the Long Island Arterial Needs Study. (Other GIS applications in the study included congestion and pavement management systems.) This GIS-safety application is employed to manage and maintain various accident-related data used to identify and rank high accident locations in an allocation process to achieve effective use of funds and the greatest possible accident reduction. The paper is organized into three sections. Section I briefly describes the accident analysis process, with emphasis on the major decisionmaking steps that take place to enable the basic functions of safety management. Section II concentrates on the potential use of GIS and other information technology to support operations of the various decisionmaking steps in the accident analysis process. Finally, a summary and conclusions are presented in Section III.
