Using GIS in the Analysis of Truck Crashes

Product Type

HSIS Summary Report


David Harkey




The objectives of this study were to (1) identify high-truck-crash locations using a GIS-based crash referencing system and (2) explore the applicability of non-traditional data bases for this type of analysis. A GIS-based system was used to identify and locate high-truck-crash locations in Wake County, North Carolina. Eighteen high-truck-crash segments (on eight routes) and eight high-crash-zones were identified. Both traditional (such as lane width and shoulder type) and non-traditional (such as locations of trucking terminals) data were used to further analyze these high-crash segments and zones. There are three advantages of using a GIS-based system to identify high-crash locations: locational referencing, incorporation of non-traditional data bases, and visual analysis.
