There are approximately 4,500 traffic fatalities at intersections each year in the U.S. One method for reducing these crashes is through equipping vehicles with Intersection Advanced Driver Assistance Systems (I-ADAS) that can detect and alert the driver of an impending crash. However, the effectiveness of these systems is expected to be highly dependent on the pre-crash acceleration behavior of drivers prior to these crashes. The first objective of this study was to use pre-crash acceleration data downloaded from Event Data Recorders (EDRs) to evaluate previously developed acceleration profile models that were based off of "typical" acceleration data. Our second objective was to develop a novel acceleration profile model using this pre-crash data. This study used EDR-recorded pre-crash speeds from 89 intersection crashes investigated as part of National Automotive Sampling System / Crashworthiness Data System (NASS/CDS). A 10-fold cross-validation procedure was implemented to generate and evaluate a quadratic-decreasing acceleration profile model developed from this pre-crash data. Our results indicate that previously generated models underestimate pre-crash acceleration behavior of vehicles involved in intersection crashes. An improved, nationally-representative acceleration profile is also presented that should be considered by researchers interested in simulating pre-intersection crash acceleration behavior. These findings have important implications for I-ADAS designers and government regulatory agencies developing and evaluating the algorithm for delivering an effective, reliable alert to the driver.
