This update provides a new formula for calculating the Zonar Coach score on the web dashboard. For a better understanding of risk levels across a fleet, this enhanced formula will span the full range of 0 to 100 and provide better visibility into how many incidents are captured.
About the Zonar Coach score
The Coach score is the go-to metric for understanding the safety risk of a fleet or driver. This score represents how many incidents were recorded in a particular time period and accounts for how much driving occurred during that time. A perfect score is 100, which means there are no unsafe driving incidents on record.
All scores will significantly change and span from 0 to 100, resolving the issue of every score being ranked in the 90s.
Making scores more accurate
Now that we have a large amount of data from Zonar Coach customers, we’ve learned more about driver safety—specifically, what type of patterns and data are normal and what it looks like when a driver is less safe. We’ve also learned which types of unsafe driving behavior are more severe than others. And we’ve incorporated this knowledge into the new formula.
The top differences:
- The core calculation is based on the number of hours driven, rather than the number of miles. This gives much more consistent scoring across high-speed vs. low-speed routes.
- The thresholds for a score of 0 are more reasonable, so that the drivers with the most incident videos are properly granted low score values.
- Based on their relative risk levels, the 7 incident categories are weighted when calculating the final 0 to 100 score.
We’re proud that the final calculation has a smooth distribution of drivers across the 0 to 100 scoring spectra.
When the new formula is deployed, all scores for all time periods will be updated to use the new calculation. This is not reversible.
