RAG scoring is the most popular scoring method.
RAG scoring stands for the Red, Amber, Green categories that drivers are assigned to in terms of their driving performance.
Achieving green is the goal.
These different color bands are configurable, meaning users can decide the thresholds for each color and make it more stringent as driver scores improve.
Users can also choose the events they want to include and have the drivers scored on. Choose up to 25 events.
Please note: Data from certain OBC types may not be available due to unit type limitations.
How is the RAG score calculated?
Making use of custom scoring, you can choose if you want to penalize a driver on a selected event based on event occurrence and or the duration of the event, e.g. over-speeded for more than 90 seconds.
- Occurrence - the RAG logic will be applied based on occurrence of that specific event (Event occurrence ÷ Distance X 100).
- Duration - the RAG logic will be based on every 10-second duration of that specific event, for example (Over Speeding duration ÷ 10) ÷ Distance) X 100
Example
The driver has travelled 2460 km’s last month. We will use this distance in his score calculation.
- He had 14 harsh cornering events, 10 harsh braking events and 19 speeding events of which the speeding events had a total duration of 5minutes and 40 seconds (340 seconds).
Calculating the score
- The score is factored over a distance to events per X km/miles where the X is configurable when setting up scoring. In this example, we used 100 (which is also the recommended default) but you can select any value as shown below.
In this example, the events were configured to be scored on as below:
- Harsh Cornering – based on occurrences
- Harsh Braking – based on occurrences
- Speeding – based on duration
- Amber threshold was set to 2- 5

Calculation |
Score |
Harsh Cornering |
14 ÷ 2460 = 0.00569 0.00569 x 100 = 0.569 |
0.57 |
Harsh Braking |
10 ÷ 2460 = 0.00406 0.00406 x 100 = 0.406 |
0.41 |
Speeding |
((340seconds ÷ 10) ÷ 2460) x 100 ((Over Speeding Time ÷ 10) ÷ Distance) × 100 Duration based scores are always expressed as seconds per 10 km/mi. This is done because duration will always be a much higher value than occurrences and needs to be normalized as well. |
1.38 |
Total Score |
Add up the three individual event scores. Based on selected thresholds the score is amber for this example. |
0.57 + 0.41 +1.38 = 2.36 |
