1. A method comprising:
- obtaining sensor measurements at a measurement rate from one or more sensors of a mobile device in a vehicle during a trip;
identifying a user of the mobile device in the vehicle as a driver of the vehicle during the trip;
monitoring, by the mobile device, behaviors associated with the mobile device during the trip in the vehicle using the sensor measurements, the behaviors comprising braking behaviors, acceleration behaviors, mobile device usage behaviors, and speeding behaviors;
computing, by the mobile device, a braking score using the braking behaviors, an acceleration score using the acceleration behaviors, a mobile device usage score using the mobile device usage behaviors, and a speeding score using the speeding behaviors;
aggregating, by the mobile device, the braking score, the acceleration score, the mobile device usage score, and the speeding score to determine a trip score for the trip in the vehicle; and
updating the obtaining of the sensor measurements for a subsequent trip in the vehicle based on the trip score, wherein updating the obtaining of the sensor measurements comprises;
adjusting the measurement rate for the sensor measurements for the subsequent trip, or selecting a different one or more sensors of the mobile device for the sensor measurements for the subsequent trip.

Abstract
Embodiments of the present invention utilize mobile devices to provide information on a user'"'"'s behaviors during transportation. For example, a mobile device carried by a user can be used to detect and analyze driving behaviors during trips in vehicles. The mobile device can further be used to assign and display scores relating to the driving behaviors, scores for individual trips, and an overall driving score for the particular user.
