CHARACTERIZING ROUTE STRESS AND STRESS-BASED ROUTE SELECTION

摘要

Stress metrics are calculated for road segments based on measured heart rates of drivers traversing the road segments. Stress metrics are calculated from normalized heart rate measurements that is normalized based on an initial heart rate measurement at the beginning of a trip. Heart rate data for multiple users may be aggregated to calculate a global stress metric for a road segment. Heart rate data from multiple traversals of a road segment by an individual may be aggregated to calculate an individual stress metric. Routes may be selected based on stress metrics. An initial route may be selected based on stress metrics in order to satisfy preferences from a driver. A new route may be selected based on stress metrics in response to detecting that a driver's current stress level exceeds a threshold condition.
