| Abstract | A safety performance function (SPF) is an equation used to predict the average number of crashes per year at a location as a function of exposure and, in some cases, roadway or intersection characteristics (e.g., number of lanes, traffic control, or median type). For highway segments, exposure is represented by the segment length and annual average daily traffic (AADT) associated with the study section as shown by the sample SPF in Equation 1. |
