Based on the results of the “Onboard Monitoring to Improve Commercial Motor Vehicle Safety” effort, this FOT will involve approximately 20 instrumented vehicles and approximately 40 drivers to determine whether onboard monitoring and feedback (real-time and delayed) can improve commercial motor vehicle driver performance and safety. It is envisioned that the technology suite will provide driver performance feedback on a number of critical safety factors including hours of service, lane keeping, steering and pedal inputs, safety belt usage, following distance, turn signal use, and hard braking and hard steering events.
