We score your driving
Driving is all about managing external elements and adapting to it. This is why our drive score assesses behaviour in context. It is a score between 0 and 100:
- 100: perfect score, your behaviour on the road is outstanding
- above 75: you drive safely
- below 50: your driving style is risky
The score is composed of 6 sub-factors: speeding, complying, cornering, accelerating, braking and resting, that are weighted according to their presence in road safety statistics, in terms of frequency and severity.
The better you behave, the better you score.
When misbehaving, the more challenging the context, the greater the impact on the score.
Six factors contribute to the score
The drive score aggregates six sub-scores, all between 0 and 100, assessing speeding, complying, cornering, accelerating, braking, and resting.
| Factor | Description |
|---|---|
| Speeding | Driving too fast and above speed limit |
| Cornering | High centripetal force in curves |
| Accelerating | Hastening and taking into account G-Force |
| Braking | Intense deceleration |
| Complying | Illegal events as illegal U-turn, illegal direction, neglect pedestrian crossing, neglect yield sign, neglect stop sign, phone unlock |
| Resting | Driving for longer than 2 hours without a break |
Context modulates intensity of actions
As explained above, a risky event needs to be seen in its specific context. Context is measured as a sub-factor, a so-called penalty. Penalties amend the measured intensity by increasing it whenever the context is considered bad, or decreasing it whenever the context is considered good, in a location-based manner. The penalties are:
- Road type (urban, rural, or motorway)
- Slippery road
- Intersection
- Roundabout
- Pedestrian crossing nearby
- Road surface in bad shape
- Dangerous road in a rural environment with high speed limits
- Bad visibility due to topology
- Traffic jam
- Driving at night
- Traffic lights
- Ongoing phone call
- Access ramp
Score trips, drivers, devices or fleets
Apart from the risk of a given trip, customers can also ask for the risk assessment of a given driver, device, or the whole fleet. For this, Motion-S exposes a set of endpoints that a customer can call and obtain risk assessment information by categories.
