Correlation between Wheelchair Users’ Great Good Place and their Life Satisfaction via using Colored Motif: focusing on Mobile GPS data

Abstract

As the necessity of mobility trajectory collecting technology using CDR or GPS data increases and research on human mobility in a hyper-connected society is ongoing, studies on urban computing have expanded in diverse ways. In particular, mobility technology minimizes spatio-temporal restrictions on the movement of people and vehicles, and this surpasses social limits by connecting diverse communication networks using GPS. This paper, however, excludes a few regional matters like individual characteristics, the density of places, and traffic congestion and solely focuses on identifying and understanding the mobility pattern of physically disabled people and that of non-physically disabled people. We compare the GPS trajectory data between the wheelchair users and non-wheelchair users and then check the correlation between the number of visited types of places and the life satisfaction. Physically-disabled people are not just random walkers but also plan their trips, deciding their stopovers and destinations like non-physically disabled people do. In this paper, we figured out the number of visited places and the types of activities by counting the number of different colors of nodes from the motifs and the total number of nodes regardless of those other colors. Consequently, we were able to find out through the correlation that the less the number of different daily colors among the total number of colors, the higher the life satisfaction of wheelchair users. Therefore, we need to listen to their demands not because of their forceful subway demonstration that was done recently, but by looking at the data in detail. However, the life satisfaction was high as the frequency and ratio of visitation of those few visited ‘great good places’ like welfare, cultural, and physical training facilities. Also, it is predictable that the demands of those places would be high. We compare this with that of non-physically disabled people.
