EROAD Rewards and accuracy Yes, but remember the expression'what can be measured, can be managed'
Having had company vehicles involved in crashes (our fleet of 60 vehicles does 1 million km per year) where the Police asked if we had GPS tracking, and then requested the data as part of thier crash investigation does tend to focus one's attention on driving pattern of behavior.
We identified the 'at risk' drivers and first had a non-judgemental conversation about safety expectations (which worked for the majority), if behavior did not improve then it was passed onto HR for our performance management process (less than a handful of individuals).
