“…The comfort in mixed space with pedestrians and PMVs and the comfort in automated driving of an automobile are considered in setting the evaluation target of comfort in the autonomous locomotion of PMVs. In a previous study of comfort in mixed space with pedestrians and PMVs [14], invasion rate and invasion time of PMVs into the pedestrian personal space were used as indices of comfort. As seen here, the characteristics of pedestrian space are that it can easily lead to encounters with scenes involving danger and pressure due to the high degree of freedom and close distance to the surrounding traffic participants.…”

“…Therefore, "reassurance" gains particular focus in this study. In addition, the comfort of PMVs in autonomous locomotion is set as a state in which there is no "collision risk", "closeness or pressure to obstacle" or "surprise against the autonomous system" by considering elements that constitute reassurance based on previous research [14] [15].…”

During the autonomous locomotion of personal mobility vehicles (PMVs) in pedestrian space, it is necessary to avoid collisions with pedestrians walking nearby. The avoidance paths of the PMVs are affected by the behavior of the pedestrians, which may also affect passenger comfort. In this study, a local path planning method considering passenger comfort is proposed to design comfortable pedestrian avoidance strategies during autonomous locomotion of PMVs in pedestrian space. First, pedestrian behaviors that affect passenger comfort are investigated by evaluating the comfort in pedestrian avoidance scenarios with different avoidance methods and pedestrian behavior. Next, requirements for a pedestrian avoidance method considering comfort are set based on the behaviors affecting passenger comfort. Finally, a novel path planning method satisfying the requirements is proposed. It is confirmed that the proposed method can generate comfortable paths in pedestrian space, and the validity of the proposed method is examined by a subject experiment.

Abstract. Personal mobility vehicles (PMVs), such as an inverted-pendulum vehicle, have been attracting attention as next-generation vehicles for individual use. However, when PMVs travel in pedestrian flows, it is necessary to consider the safety and comfort of pedestrians. This paper investigated a simulation model considering the interaction between multiple PMVs and pedestrians, and analyzed the effects of PMVs in pedestrian flows using the concept of personal space. Furthermore, we proposed an assistance system for PMVs in order to ensure comfort for pedestrians in the presence of PMVs. The simulation results revealed that the avoidance angle and the velocity of PMVs significantly affected the invasion of pedestrians' PSs, and the effectiveness of the assistance system was clearly confirmed.

“…A potential solution to these problems is to reduce the use of individual cars in urban areas by encouraging city dwellers to use public transport for their daily commuting necessities and personal mobility to access the nearest public transport hubs and shopping centers, as well as for other short distance journeys. In the literature, the problem of reaching the nearest transportation hub is referred to as the last-/first-mile problem [7][8][9][10][11][12][13].…”

“…is study focuses on personal mobility vehicles, which offer a promising solution to the last-/first-mile problem and might thereby help realize effective, accessible, and multimodal public transportation networks for urban areas. Personal mobility vehicles are defined as transportation devices for individual use [10,11,13]. Several vehicles (e.g., electric scooters, single-seater mobility devices, and wheelchair-type mobility devices) are considered as personal mobility vehicles.…”

To significantly reduce the occurrence of severe traffic accidents, reducing the number of vehicles in urban areas should be considered. Personal mobility is essential for realizing this reduction, which requires consideration of the last-/first-mile problem. The overall objective of our research is to solve this problem using standing-type personal mobility vehicles as transportation devices; however, to evaluate the feasibility of such vehicles as future mobility devices, it is necessary to evaluate their operation under real-world conditions. Therefore, in this study, experimental and survey data relating to the velocity, stability, safety, and comfort of a standing-type personal mobility device are obtained to evaluate its performance in three different scenarios. The results show that the personal mobility vehicle is socially well received and can be safely operated on sidewalks, irrespective of the gender or age of the driver; moreover, the results suggest that subjects who routinely use a bicycle are adept at avoiding and absorbing the impacts of small holes and bumps, thereby yielding reduced acceleration values (in all directions) and pitch, roll, and yaw rates. This is anticipated to benefit the future development of personal mobility devices and help realize effective and accessible public transport systems, as well as reduce the number of vehicles in urban areas.
