Summary
This study investigates the efficacy of high-fidelity simulator training in improving real-world fuel efficiency for Commercial Driver’s License (CDL) truck drivers. The research addresses the need for cost-effective and safe methods to enhance driver performance, specifically focusing on whether skills acquired in a simulator transfer to actual driving conditions. The primary objective was to quantify improvements in fuel economy and determine the durability of these gains, as well as identify which driver characteristics influence training outcomes. The study involved forty employees from a local commercial trucking company, aged 25 to 66, with varying years of tenure. Participants underwent a two-hour fuel management training program delivered by GE Driver Development. The curriculum consisted of 19% lecture, 24% computer-based training, and 57% simulator training using the TranSim VS™ simulator. The training focused on optimizing shifting techniques, including progressive shifting, double clutching, timing, and gear selection. To assess transfer of training, researchers collected monthly fuel consumption data (miles per gallon) from the drivers’ own vehicles over a six-month post-training interval. Results demonstrated that simulator training significantly increased fuel efficiency by an average of 2.8% over the six-month period ($F(1,39)=14.23, p<.01$). The benefits were durable, persisting throughout the entire post-training interval, although a modest decline in improvement was observed over time, dropping from approximately 4% in the first two months to 2.5% by month six. Analysis by pre-training performance quartiles revealed that drivers with the lowest initial fuel efficiency benefited most, showing over 7% improvement, whereas those with the highest pre-training efficiency showed no significant benefit due to ceiling effects. Furthermore, the training effects were independent of driver age and job tenure. Crucially, drivers who changed vehicles after training showed similar improvements to those who did not, indicating that the training imparted a generalized skill rather than vehicle-specific knowledge. The findings validate the transfer of simulator-based training to real-world driving, confirming that such programs effectively reduce operating expenses for commercial fleets. The study concludes that simulator training is particularly valuable for drivers with below-median fuel efficiency and that the acquired skills are robust, transferring across different vehicles and persisting over time. This supports the use of high-fidelity simulation as a practical tool for enhancing driver efficiency and economic performance in the trucking industry.
