Yesterday, a CSA study came out questioning the correlation between the CSA BASIC scores and crash data. It's the most recent in a series of reports that either prop up the CSA's methods, or debunks them. If you're keeping score:
- Wells Fargo (PDF) came out with a report saying there was no correlation
- UMTRI (PDF) came out with a CSA study saying Unsafe Driving and Fatigue Driving had a strong correlation (it had a number of other important conclusions, as well)
- An engineer named Inam Iyoob ran a report for the Alliance for Safe, Efficient, and Competitive Truck Transportation saying CSA scores were not a predictor of crashes
Everyone has a dog in this fight in this except for the University of Michigan, which does a great deal of work with companies, government, and trade groups. It's the one group whose main motivation is neutrality. So we tend to give its CSA study a little more weight.
Anyway, as a fleet safety or operations person, you should read through it and decide for yourself. For us, below you can see one way to answer, "Does CSA Matter?"
