What are the results of the Operational Model (Op-Model) Test?
The Op-Model Test is being formally evaluated by a third party – the University of Michigan Transportation Research Institute. The evaluation will compare the test group to the control group in the four original Test States as well as impacts in additional CSA 2010 Test States. To date, feedback from the enforcement staff using the Safety Measurement System (SMS) and conducting new interventions has been positive. Preliminary results from the Op-Model Test suggest that CSA 2010 offers a more efficient, effective means of identifying and intervening with motor carriers that have demonstrated safety performance issues. In particular, the Op-Model Test is demonstrating the following: • CSA 2010 enables enforcement staff to investigate more carriers with safety deficiencies using the same number of resources. • The warning letter is encouraging carriers to recognize and address their safety deficiencies earlier, and carriers are responding. • CSA 2010 is having a positive impact on motor c
