Auxiliary Power Unit

APU’s provide a larger array of comfort features for drivers looking to reduce idling. APU’s can provide heat, air conditioning, power for household electrical devices and engine heat. Most devices combine a small heater, a compressor for air conditioning and an alternator. APU’s may be powered by diesel fuel directly from the tractor fuel tank, or by a bank of rechargeable batteries. Diesel driven APU’s can operate for 5 hours or more on a single gallon of diesel fuel. Costs for these devices can range from $3500 to $9000, but are typically in the $6000 to $7000 range. For a partial list of manufacturers and device specifications, please visit the SmartWay website at http://www.epa.gov/otaq/smartway/idlingtechnologies.htm. For locomotives APUs automatically shut down the main locomotive engine idle while maintaining all vital main engine systems at greatly reduced fuel consumption.

Onboard Monitoring – FOT

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.
