SafeGuard evaluates 13 behavioral habits: fatigue, distraction, long continuous driving, speeding, following, mobile phone use, aggressive lane changing, solid line lane changing, seatbelt, deceleration, cornering, acceleration, and smoking.
It then groups those habits into four evaluation dimensions:
- Consciousness score
- Robustness score
- Compliance score
- Attention score
Aggressive driving measures whether the driver drives aggressively. It applies speeding, following too closely, aggressive lane changes (frequent lane changing to overtake, continuous multi-lane changes, and changing lanes while following too closely), sharp turns, harsh deceleration, harsh acceleration, and lane departure. SafeGuard calculates the score from the frequency and risk level of those events. Contributing habits: aggressive lane change, lane keeping, following distance, speeding, acceleration, deceleration, and turning.
Violation driving measures whether the driver complies with traffic rules. It applies changing lanes over a solid line, not wearing a seatbelt, using a mobile phone while driving, smoking, and long continuous driving. Contributing habits: long continuous driving, solid line lane change, mobile phone use, smoking, and seatbelt.
Fatigued driving measures whether the driver stays alert. It applies the degree and duration of the fatigued state from real-time risk assessment. Contributing habit: fatigue.
Distracted driving measures whether the driver stays focused. It applies the degree and duration of the distracted state from real-time risk assessment. Contributing habit: distraction.
Lower scores mean higher risk Across all four dimensions, a lower score means a more dangerous driving process.
