This study examined the relative effects of education and eco-IVIS(in-vehicle information system) to reduce fuel consumption and greenhouse gas emissions. Also the study investigated the increasing of driving workload when drivers interact with intervention technique, Thirty participants randomly assigned into two groups(training and eco-IVTS) and conducted driving before and after the each intervention tech¬nique, While driving, we observed three driving behaviors: Frequency of excessive RPM, percent of speeding, and mean fuel efficiency. Also the Driver Activity Load Index was used to rare participants` subjective ratings of driving workload. Although the results showed positive impact of both education and eco-IVIS to increasing the eco-driving behaviors, eco-IVIS was more effective than education. However, we found comparable level of driving workload in the education and eco-IV1S.

This study implemented self-management technique to improve supervisory behaviors at a construction site. Self-management in the current study consisted of goal setting, self-monitoring and providing reward for two supervisory behaviors; (1) conducting safety observations of workers safety behavior and (2) providing safe related feedback. Two supervisors severed as participants. An AB within-group design was adopted. After baseline (A), self-management technique was implemented(B). Results suggested that self-management was effective in increasing the two supervisory behaviors. Moreover, the increased supervisory behaviors were associated with improvement in workers` safety performance.

This study examined the relative effects of feedback frequency and specificity of Eco-IVIS(eco in-vehicle information system) on the fuel-efficiency and workload. Eighty participants randomly assigned into four experimental groups (high frequency/specific, high frequency/global, low frequency/specific, and low frequency/global feedback) and they drove 16.4Km motorway under the each feedback condition. The dependent variable were fuel efficiency and Drive Activity Load Index which measured participants’ subjective ratings of driving workload. The results showed that high frequent feedback was more effective for increasing fuel-efficiency than low frequent feedback, however, there was no significant difference of fuel-efficiency between specific and global feedback. Although, overall DALI score was comparable among four experimental conditions, visual demand score was significant higher under the high frequent feedback condition than low frequent feedback.

The purpose of this study was to examine the effects of goal-setting on Eco-driving behaviors. An additional purpose was to examine whether setting goals on target behaviors had spread effects on non-target eco-driving behaviors. Three office workers who drive regularly participated in this study. An AB multiple baseline design was adopted. After baseline (A), participants set goals on two or three target behaviors(e.g., over speeding, put the gears in neutral, extreme acceleration) (B). Results showed that goal-setting was effective in increasing the targeted eco-driving behaviors. In addition, most of the non-target eco-driving behaviors(e.g., extreme break, extreme acceleration) increased

This study examined the effects of safety-aisle on the safety climate, safety leadership, safety behavior, work loading and perceived accident risk in the small sawmilling industry. We distributed a questionnaire that measured various demographic variables, safety related variables by mail to 200 sawmilling companies. Finally 59 managers’ and 129 workers’ questionnaires were used for data analysis. An independent t-test was conducted to identify significant mean differences of safety related variables between safety-aisle installed and non-installed companies. Results indicated that mean differences of safety climate and safety behavior between safety-aisle installed and non-installed companies were significant. However, mean differences of safety leadership, work loading and perceived risk were not significant at the p < .05 level. Based on these results, the implications of this study and suggestions for future research were discussed.
