Driver Safety Score Calculation
The Driver Safety Score is calculated based on the number of unsafe events triggered by a driver and the distance traveled during the day. The score is adjusted in real-time and considers the minimum and maximum thresholds for various safety events.
Here's how it works:
-
Checking the Basics: First, we check if you’ve driven enough distance for the day, at least 10 kilometers (6.2 miles). If not, we can’t give you a score for that day.
-
Counting Events: Next, we count any unsafe driving events, like sudden braking or sharp turns. But if you do the same unsafe thing more than once within a minute, we only count it once. This makes sure we don’t unfairly penalize you for small mistakes.
-
Calculating Event Rate: Then, we look at how often these unsafe events happen compared to how far you’ve driven. This gives us a rate of unsafe events per 100 kilometers.
-
Weighing the Events: Not all unsafe events are equal. Some are more serious than others. We give each type of event a weight to show how important it is. For example, harsh braking might have more weight than lane drifting.
-
Comparing to Thresholds: We have set limits for each type of event. If you go over these limits, your score starts to decrease. It’s like a warning that you need to drive safer.
-
Calculating Scores: Based on all this, we calculate a score for each type of event. If you’re close to the limits, your score will be lower. But if you’re driving safely, your score will be higher.
-
Adding Up the Scores: Finally, we add up all the scores for each type of event to get your overall safety score. The higher the score, the safer you’re driving.
-
Taking Distance into Account: To make it fair, we also look at how far you’ve driven each day. This helps us give more weight to days where you’ve driven more.
-
Period Safety Score: We calculate your overall safety score over a period of time, like a week or a month.
