移動軌跡が作る面積と外周の間の統計則と個人属性

抄録

Using data on the movement trajectories of approximately 15,000 people per day passing through Urayasu City, Chiba Prefecture, in August 2022, we confirmed that there is a strong correlation between the area and perimeter of the polygons they depict. The correlation parameters showed that the trajectories of people moving long distances of 5 (km) or more are linear. This trend is stronger on weekends and holidays. On the other hand, the trajectories of people moving short distances of less than 5 (km) are circular or square, enclosing a large area. This trend did not change significantly between weekdays and weekends or holidays. Analysis was also carried out according to the attributes of gender and age, which are added to the movement track data. The results showed that the linear trend for long-distance movement was stronger for women than for men. For age groups, the trend was stronger for those under 30 years of age. These results mean that long-distance movers have a specific destination and move in a straight line to and from that destination, and that this tendency is stronger among women under 30 years of age.
