Abstract—This study describes a microscopic simulation model considering the interaction between a personal transporter and multiple pedestrians and proposed an avoidance assistance system using the concept of personal space, which is the space in which invasion by others induces a psychological strain. The simulation was examined under the condition that the personal transporter traveling toward pedestrian flow under different conditions of road width and different pedestrian densities. To evaluate the mutual effects of a personal transporter on nearby pedestrians, the invasion ratio and crossing time were introduced as evaluation indexes. The simulation results reveal that the effectiveness of the assistance system was clearly confirmed. In particular, the personal transporter equipped with the assistance system had invasion ratio and crossing time lower than those of the personal transporter without such system.
