The field of personal mobility is experiencing rapid growth worldwide, driven by the proliferation of shared services and its appeal as an environmentally friendly and convenient mode of transportation. However, the increasing number of safety incidents involving users and pedestrians, attributed to factors such as user inexperience and inadequacies in regulatory frameworks, raises concerns. In this study, we employ text mining techniques to analyze the public perception of safety in personal mobility and propose policy alternatives to promote the development of the personal mobility industry. Specifically, our recommendations include: 1) Advancing technological sophistication through the development of camera-based Vision Positioning System (VPS) technology, augmented reality (AR) technology, and support for helmet materials and innovation research; 2) Improving business models by introducing distance-based charging mechanisms; 3) Strengthening infrastructure through enhanced battery safety measures, expansion and enhancement of bicycle lanes and roads; and 4) Reinforcing safety verification tests by developing and supporting a safety speed monitoring system and introducing specialized licenses for personal mobility operation.
