Recently, interest in the first/last mile has increased with the development of personal mobility vehicles (PMVs), a new eco-friendly and easy-to-use transportation mode. As shared transportation has become more active, existing pedestrians have begun using shared PMVs (e.g., e-scooters and bicycles). The main purpose of this work is to compare and analyze the travel characteristics of each shared-PMV usage group and short-distance travel group, interpret intergroup relations, and calculate the benefits of introducing shared-PMV as an alternative means of short-distance travel. First, the data of shared-PMV usage in Korea were analyzed to understand the characteristics (average number of days of use, average time of use, user growth rate, etc.) of the shared-PMV usage group. Mobile data analysis distinguishes the travel mode and extracts short-range travel groups that fit the scope. The travel modes are distinguished by the variables of mobile data (travel speed, department time, travel distance, travel time, etc.), and the short-distance group consists of short-distance passenger cars and pedestrians (main mode and access mode). This study presents similarities and differences between shared-PMV and short-distance groups via mobile data and evaluates the time, cost, and environmental benefits of introducing shared PMVs as a medium distance.
