Driving safety is assessed on the basis of a dynamic model of the vehicle. Our algorithm is based on the main physical characteristics of the vehicle (weight, wheelbase, engine, body type, etc.) by estimating the adherence between the tire and the road throughout the trip.
The safety score is calculated according to the distance of your journey and the number of occurrences of safety events (risk events). The app is able to detect high accelerations and sudden braking as well as exceeding adherence thresholds. The overall safety score includes these three variables (acceleration, braking, and adherence). The rating takes into account the road context (urban, extra-urban, motorway).
