Project description

Project description

  • To design and implement an application that monitors users’ driving behaviors in real time, using on-device sensors

    • GPS data is used to calculate the driving speed and road conditions (highway or local) if possible

    • Gyroscope and accelerometer combined are used to detect moving trajectories such as making turns, changing lanes, etc.

  • Two components

    • Driving data collector runs on Android

    • Algorithm for evaluating driving behavior runs in SIS

Evaluation algorithm

Evaluation algorithm

  • Composite values are used

    • acc= sqrt(accX*accX+ accY*accY + accZ*accZ)

    • rot = sqrt(rotX*rotX+ rotY*rotY + rotZ*rotZ)

  • Four unsafe patterns and empirical thresholds

    • Hard acceleration/deceleration (Acc)

    • High speed turn (Acc * Rot, & V)

    • Swing between lanes (Rot * V)

    • Cellphone use (Rot & V)

  • 5s evaluation window
