Identifying Hazardous Locations Using Geographic Information Systems

摘要

The Report describes work conducted at North Carolina A&T State University andNorth 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 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.
