Advanced Driver Assistance System Crash Rate Assessment

This technical report presents a study on the use of Vehicle Miles Traveled (VMT) data for evaluating the effectiveness of Advanced Driver Assistance Systems (ADAS). The research utilizes a comprehensive dataset collected from various vehicle manufacturers in collaboration with the National Highway Traffic Safety Administration (NHTSA). The study aims to validate the Quasi-Induced Exposure (QIE) method for analyzing ADAS effectiveness by assessing rear-end struck vehicle crash rates for vehicles equipped with Automatic Emergency Braking (AEB) systems. It outlines the data collection methods, including telemetry-based and dealer-visit data, and discusses the challenges of data variability among manufacturers. The findings indicate that aggregated measures of VMT can effectively support safety analyses while maintaining data quality. The report emphasizes the need for standardized reporting protocols to enhance the utility of pooled datasets and suggests that the insights gained can inform future traffic safety research and interventions.
