Presentation technique for bicycle safety information system and its effectiveness verification

In this study, we conducted bicycle riding experiments that focus on the method of information presentation by an automated system to cyclists, with the intent to design an information system related to bicycle safety information. In an evaluation of information presentation, we confirmed that auditory presentation was the most effective from the viewpoints of both recognition and comprehension. In addition, information presented using the auditory method was more likely to be recognized than information presented using the visual and tactile method combined. The results of the analysis of variance for recognition showed that the visual presentation method had no significant effect. In addition, the experiments involved behavioral observation using the system and a questionnaire survey on changes in behavior before and after experiencing the system. The results showed that information was correctly conveyed by the system using a combination of auditory, tactile, and visual presentation methods, regardless of the users' degree of awareness of the system. Two weeks after the experiment, a survey was conducted to investigate the changes in the participants' awareness and behavior regarding risky or illegal riding. The results showed an improvement in the awareness of risky or illegal riding in daily life and an increase in right behavior, confirming the effectiveness of this system. Consequently, the results demonstrate the effectiveness of the system and provide knowledge for realizing a bicycle riding safety support information system.
