IDENTIFYING HAZARDOUS LOCATIONS USING GEOGRAPHIC INFORMATION SYSTEMS. FINAL REPORT

This report describes work conducted at North Carolina A&T State University and North Carolina State University, which used the increased capabilities offered by geographic information systems (GIS), along with the detailed mapping (which contains highway features and geometrics) available for Guilford County, North Carolina, to demonstrate the use of engineering knowledge regarding accident causation to identify hazardous locations. The general approach taken was that of the pilot study where a subset of information is used to demonstrate how a new technology (in this case GIS) may be used to solve a particular problem or problems. The mapping data available from the County, along with various other data files, the MapInfo GIS, and North Carolina's Accident Records System (ARS) were used to conduct the study. The project provided valuable information regarding the limitations and advantages of using engineering knowledge about accident causation for identifying "hazardous highway locations", and demonstrates the utility and difficulties of the GIS applied to ARS. Major findings include: the "feature-based" approach to identifying hazardous highway locations is viable; and, there exist many difficulties with data quality in the existing system which must be addressed.
