Attitude Survey of Youth for Mutual Aid Support System for Local Community Using Bayesian Network

Some Hiroshima citizens live in suburban residential estates at the slope of mountains surrounding the city, but the living environment is unsuitable for “vulnerable road users” mainly elderly people. To improve their living environments, we have shown the concept of information sharing system to support them living in regions where public transport is not sufficiently developed. In addition, we have constructed a web service to support their daily life named MASS. Our system’s role is to facilitate the encounter between local community people, provide the opportunity of resource sharing, generate some kinds of transport means, and solve the difficulties in daily life by mutual aid. Young people’s active participation is essential to make our system more effective for vulnerable road users because most of the skills will be provided by young people. The analysis of the previous work unveiled a trend of the youth consciousness about skill sharing in their local community and found the limitation of Quantification Method Type II. Therefore, in this paper, to discuss our system’s continuity as a business, we conducted an attitude survey on young people’s awareness of resource sharing in their local community and analyzed it with Bayesian network. From the experimental result, we re-confirmed the findings of the previous research and further clarified the relationship between the factors that we could not clarify so far. In addition, we conducted numerical experiments using the constructed Bayesian network, obtained results that support several hypotheses, and revealed factors that have a strong influence on the use of MASS.
