Summary

This study evaluates the effectiveness of driving simulator training for snowplow operators within the Arizona Department of Transportation (ADOT). The research was motivated by the high risks associated with operating $200,000 heavy equipment in blinding snowstorms and the limitations of traditional on-the-job training, which often consisted of only two or three shifts with a partner-trainer. The primary objective was to determine if simulator-based training could enhance driver safety, improve skill transfer to real-world operations, and reduce operational costs such as equipment repairs and liability claims. The evaluation, conducted by an interdisciplinary team from Arizona State University, spanned two winter seasons. In Year One (2004–05), ADOT contracted with L-3 Communications to provide mobile simulator training to 149 drivers across five rural districts. This introductory course included classroom instruction and simulator segments. In Year Two (2005–06), ADOT procured a dedicated simulator for the Globe Maintenance District, where all 61 drivers underwent more intensive training led by experienced local operators. This training focused on situational awareness in the fall and fuel management and shifting skills in the spring. The researchers employed a mixed-methods approach, utilizing mid-season surveys, end-of-season focus groups, supervisor interviews, and ride-along task analyses to assess qualitative driver responses. Quantitative assessments compared historical data on accidents, repair costs, and liability claims from 1999–2006 against baseline figures, adjusting for exposure metrics such as miles plowed and snowfall amounts. The findings revealed distinct differences in training effectiveness based on driver experience and skill type. Qualitative data indicated that newer drivers found the simulator training highly beneficial for tactical skills, such as situational awareness, while experienced drivers felt it offered little new information unless it addressed complex multi-tasking scenarios. The fuel management and shifting training, which targeted control-level skills, was well-received by drivers of manual transmission vehicles, who reported immediate application of techniques to improve fuel efficiency. Quantitatively, the results were inconclusive regarding accident reduction due to the low frequency of crashes and small sample sizes. However, when repair costs and liability were normalized for exposure, the Globe District showed improved performance metrics after the intensive Year Two training. Additionally, the study highlighted the broader economic significance of efficient snow removal, noting that delays in commercial shipping could cost millions of dollars annually. The study concludes that simulators are a valuable component of a comprehensive winter maintenance training program, particularly for training tactical skills in new hires and control skills related to fuel efficiency. The authors recommend refining training programs to address the specific needs of different driver experience levels, enhancing scenario realism, and utilizing simulator feedback to reinforce proper driving techniques. Based on these findings, ADOT expanded the program by procuring additional simulators for other districts. The research underscores the potential for simulators to reduce operational risks and costs, advocating for continued quantitative documentation to validate these qualitative benefits.

Key finding

Simulator training showed a trend toward reduced equipment repair costs for trained drivers in the first year, and qualitative feedback confirmed positive transfer of tactical awareness and control skills to on-the-job performance.
