V2X Interactive Lighting and Warning UI Design to Prevent Personal Mobility-Vehicle Collision Accident

다국어 초록 (Multilingual Abstract)

Objective: The aim of study is to prevent collision accidents between personal mobility and vehicle. This study suggests a new infrastructure called V2X interactive lighting and warning UI system. Background: The lack of securing visibility, which occurred by a blind spot in both features of the vehicle pillar and outside geography, is a pain point of vehicle drivers. Personal mobility drivers keep high-speed riding without the perception of hazardous areas, and this is the significant reason to lead a collision accident. Therefore, measures are required to prevent personal mobility-vehicle accidents by securing visibility and inducing speed reduction. Method: This study distinguishes the types of blind spots through case analysis of collision accidents between personal mobility and vehicle. It proposes the V2X system as the intelligent road infrastructure, which directly transmits and receives significant traffic or road information beyond the vehicle drivers’ visibility. This paper decides to adopt the C-V2X system with lots of advantages by acknowledging the status of being established by policy implementation. To define a warning UI system, this study specifies navigation warning UI guidelines through the previous research case. Ultimately, this paper selects the left turn situation at the intersection, representing the type of the highest dangerous areas, to further deducing storyboards and UI scenarios. Results: The V2X interactive lighting system collects personal mobility drivers’ location data and emits light sequentially when approaching unpredictable areas. When it lights, the warning UI provides pop-up messages and voice guidance according to three steps of warning flow. Specifically, this study determines the timing of emitting LED studs by calculating the average recognition time according to the riding speed of the personal mobility drivers. The system increases vehicle drivers’ awareness of the high-risk areas and induces personal mobility drivers’ deceleration. It is the reason that why this study mentions the term of interaction. Interactive lighting, which induces preemptive consideration for each driver, possesses comprehensive visibility by illuminating the road and takes responsibility for our safety. These lights are also a bridge, in other words, which helps interaction between vehicle and personal mobility that has been insufficient so far. Conclusion: Expanding visibility improves the quality of safe driving for both drivers. The proposed systems, which are V2X interactive lighting and warning UI, solve the persistent collision accident between personal mobility and vehicle. In conclusion, it has the potential to increase the value of personal mobility as a means of upcoming transportation. Application: The proposed system in this paper effectively prevents accidents by being placed at intersections identified as representative hazardous areas.
