Enhancing Safety with a Mutual Assistance System for Automobile
Author information

2015 Volume 8 Issue 2 Pages 161-170


Recently, a number of safety assistance systems for automobiles have been proposed. Most systems, such as adaptive cruise control systems (ACC), attempt to assist in improving driving safety for individual drivers. The authors' study focuses on a new type of safety assistance system, by which drivers are able to mutually assist each other based on a “Mutual Assistance” paradigm. The authors' previous study examined the effectiveness of the mutual assistance system from both the recipient and assister side with a driving simulator. In this paper, the effectiveness of a mutual assistance system is examined with a more detailed analysis. The results of experiments from the assistance recipient side indicate that early warning from a mutual assistance system statistically decreases the risks of collision by increasing the margin of collision avoidance. The results from the assister side indicate that a mutual assistance system brings positive attitude changes and enhances self-efficacy, particularly by including some voluntary actions. From the results of experiments the authors' proposed system is expected to contribute to a much safer driving environment by reducing the target level of risk.
