  1. CS 2310 Final Project-Driving Behavior Monitor Haifeng Xu Dec. 5, 2013

  2. 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

  3. Android driving data collector

  4. 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

  5. Running results in SIS

  6. Thanks!
