Google Research has developed a new method for assessing road safety by analyzing hard-braking events (HBEs) captured through Android Auto. These events, defined as sudden decelerations exceeding a specific threshold, serve as a more frequent and thus leading indicator of crash risk compared to traditional police-reported crash data. By correlating HBE frequency with historical crash statistics in California and Virginia, researchers found a significant positive association, suggesting HBEs can provide a denser and more proactive measure for identifying high-risk road segments.
