Self-perception of Assister Driver Responsibility and Contribution in Mutual Assistance System
Noting the current deep interest in advanced driver assistance systems (ADAS), this study focuses on the “mutual assistance” paradigm, by which drivers mutually assist each other to promote a safer automobile culture. In our previous study, we examined the effectiveness of mutual assistance systems from both the recipient and assister sides using a driving simulator. In this paper, assister attitude changes, especially those related to their responsibility and contribution to an incident/accident, are compared for manual, semi-automatic and automatic warning scenarios. The results indicate that more positive attitude changes will result if “participants felt that he/she had some responsibility related to accident”. Additionally, it was determined that semi-automatic warnings were most likely to engender feelings of responsibility in an assister. These experimental results indicate that semi-automatic mutual assistance system is the most effective examined technique for reducing the target level of risk.
