Summary
This study addresses the persistent problem of occupational road accidents among professional drivers, specifically within the Swedish telephone company, Televerket. Despite technical improvements in vehicles and infrastructure, driver behavior remains a critical safety factor, yet there is limited empirical evidence regarding the effectiveness of various behavioral countermeasures. The research aims to experimentally compare four distinct interventions—driver training, road safety campaigns, group discussions, and bonus systems for accident-free driving—to determine which methods most effectively reduce accident risk and associated costs. The experimental design involved five groups of approximately 900 drivers each, matched for prior accident involvement, employment time, and driving environment. Four groups served as test groups, each implementing one of the four measures, while the fifth served as a control group that received no intervention. The study evaluated outcomes over a two-year period following the implementation of the measures. The driver training program included manoeuvring, skid simulation, and commentary driving designed to highlight driver limitations rather than just improve skills. The campaign consisted of five seasonal meetings with video presentations and pamphlets. The group discussion method utilized small-group decision techniques to identify problems and commit to behavioral changes. The bonus system offered financial rewards to entire working units based on collective accident-free performance. Accident risk was calculated as accidents per 10,000 km, and accident costs were derived from company and insurance records. The results indicated that driver training, group discussions, and the bonus system significantly reduced accident risk compared to the control group, with driver training and group discussions showing the largest reductions. The campaign group showed no statistically significant reduction in accident risk. Regarding accident costs, all four experimental groups demonstrated a reduction, whereas the control group did not. Notably, the group discussion measure was particularly effective in lowering costs, reducing them from approximately SEK 800 per 10,000 km to SEK 300 per 10,000 km. Statistical analysis confirmed significant risk reductions for the training, discussion, and bonus groups, while the campaign and control groups showed no significant change. The study concludes that behavioral interventions can effectively improve road safety in large organizations, but their success depends on the specific method employed. Traditional campaigns were ineffective, whereas methods that engaged drivers in recognizing their limitations (training) or fostering social responsibility and problem-solving (group discussions and bonuses) yielded positive results. The findings suggest that companies should prioritize interactive and socially oriented measures over passive information dissemination to achieve meaningful reductions in both accident frequency and economic losses.
