Modeling Highway Accidents Using Spatially and Temporally-Explicit Event Data: A Southeastern Pennsylvania Pilot Study

Using individual accident records provided by the Pennsylvania Department of Transportation (PennDOT), and covering the 2007 to 2012 period, this project will develop a series of statistical models of accident frequency on federal and state 4-lane, controlled-access roads in Southeastern Pennsylvania. The dependent variable will be the frequency of accidents per month per 1-mile or 2-mile roadway segment by time of day and accident severity. The independent variables will include: (1) car and truck traffic volumes, speeds, and congestion levels; (2) weather and visibility conditions; (3) Roadway capacity, lane counts, and geometry measures; (4) Measures of intersection frequency and type; and other measures of facility design, capacity, and use. Should the pilot study yield robust results, we would later make it statewide in scope
