Summary
This study evaluates the effectiveness of simulator-based training for snowplow operators, specifically assessing potential reductions in fuel consumption and drivetrain maintenance costs for the Arizona Department of Transportation (ADOT). Motivated by rising diesel prices and environmental concerns, the research investigates whether the Fuel Management Driving Techniques (FMDT) course, delivered via the L-3 TranSim VS III simulator, improves operational efficiency. The study focuses on the Globe District, where simulators were deployed in 2005, and utilizes Kirkpatrick’s four-level evaluation model to measure training impact across reaction, learning, performance, and results. The methodology combined simulator assessments with real-world field tests and historical data analysis. Researchers established a 168-mile round-trip test route on US 60, featuring steep grades and winding roads, to measure fuel economy. Five newly hired drivers performed pre- and post-training runs in both manual and automatic transmission trucks equipped with GPS telemetry. Additionally, the study analyzed three years of aggregate fuel and repair records for the district’s heavy vehicle fleet, focusing on high-mileage work activity categories before and after the 2006 training implementation. Findings were mixed across evaluation levels. At the reaction level, drivers reported increased awareness of fuel-efficient behaviors. At the learning level, experienced drivers showed improved simulated fuel economy, while novices did not consistently improve. In real-world performance, drivers of manual transmission trucks achieved an average 4.5% improvement in fuel economy post-training. Conversely, automatic transmission trucks showed a 6.1% decrease in fuel efficiency, potentially due to drivers overriding programmed shifts or inconsistent ambient temperatures affecting vehicle performance during testing. Aggregate fleet data revealed no clear reduction in driveline repair costs for the winter of 2007, though excluding one major transmission repair suggested a potential decrease. The study noted that external variables, such as vehicle age and terrain, complicated the isolation of training effects. The research concludes that while simulator training shows promise for improving manual shifting techniques and fuel economy, current evaluation methods are hindered by fragmented data systems and inconsistent training delivery. The authors recommend integrating simulators more fully into ADOT’s field training programs, establishing a state-level champion for simulator initiatives, and developing a unified fuel usage reporting system to provide drivers with immediate feedback. They also suggest refining training protocols for automatic transmissions and addressing simulator downtime to maximize the operational and economic benefits of the technology.
Key finding
Drivers of manual-shift trucks achieved an average 4.5% improvement in fuel economy following FMDT training, whereas automatic transmission trucks showed a 6.1% decrease in fuel economy.
