The objectives of this study were to determine the accuracy of global positioning system (GPS) units as a traffic crash location tool, evaluate the accuracy of the location data obtained using the GPS units, and determine the largest sources of any errors found. The analysis showed that the currently used GPS unit is capable of obtaining accurate latitude and longitude data at a crash site that would allow the site to be properly located. However, substantial differences were found between the location of some crashes as identified with the GPS and milepoint (CRMP) data. Of a sample of 100 random crashes, 55 percent were found to have an accurate GPS reading and 58 percent were found to have an accurate CRMP location. There was a large range in the difference between the GPS and CRMP data by county and police agency. This shows both the accuracy that can be obtained with proper training and use as well as the lack of proper training and/or use of the GPS units at some jurisdictions.
