Sudden braking data can predict dangerous roads before crashes happen.
Google uses everyday driving data to spot accident hotspots before they become statistics.
Deep Dive
Google researchers found that roads with frequent hard-braking events, collected anonymously from Android Auto, have a significantly higher crash risk. By analyzing 10 years of data from California and Virginia, they proved these events are 18 times more common than crashes, providing a dense, real-time signal. This turns reactive crash data into a proactive safety tool, allowing cities to identify and fix dangerous roads much faster.
Why It Matters
This enables cities to proactively improve road safety using real-time driver behavior instead of waiting for accidents.
