Risk driving behaviors are the main causes of commercial vehicle crashes. In order to improve drivers’ behaviors, safety educations are frequently adopted by fleet managers. Behavioral Based Safety (BBS) is a popular education method that used to improve risk driving behaviors in the transportation area. However, the BBS education setting, which refers to combination of education frequency and materials, varies in different studies. It is uncertain which BBS education setting is more appropriate. This study was conducted to evaluate the BBS education effects and compare different education settings. Forty five participants in Shanghai were recruited to participate in the BBS experiment, which contains 13 weeks baseline phase and 13 weeks feedback phase. The participants were divided into three groups, where three different education settings were adopted. During the baseline phase, safety-related events were recorded using event-triggered video recording equipment and risk driving behaviors were captured, while in the feedback phase drivers were educated base on the individual risk driving behaviors identified in events. Negative binomial (NB) model was first used to assess the relationship between education and safety-related event occurrence frequency, effects of driver age and mileage were also considered. Results showed that education have substantial influence on safety-related event occurrence. Besides, before-after (BA) analyses were conducted to evaluate the effects of three different education settings based on relative risk ratios. The education setting which used video materials with fixed frequency provided the lowest relative risk ratio, which was recognized as the most promising education setting among the three.
