구조방정식모형(SEM)을 활용한 교통약자 이동편의시설의 만족도 요인분석

다국어 초록 (Multilingual Abstract)

Due to increasing life expectancy and declining birth rate, Korea is becoming a aging society in which aged population takes place 10.3% in total population; however, provision of facilities for the elderly and disabled people are insignificant. In order to enhance socio-economic participation and provide equal right of mobility for the disabled people, more investment for transportation related facilities are necessary. Currently, the facilities with lower installation rate and higher satisfaction factor have an investment priority. Namely, a separate improvement plans are performed without considering a cause and effect relationship between installation rate and satisfaction factor. In other words, without a specific rules of operation for investing disabled facilities, the local governments allocate budget to the region that has a more disabled population and lower installation rate.
In this study, a combined analysis method between facility and its satisfaction is provided for use in disabled facility investment plans. By using a Structural Equation Model(SEM), we can analyze a cause and effect relationship between mobility disabled facility and its satisfaction.
Yesan-City which has over 65 aged population rate is more than 20% and has become a post-aged society is selected. Survey for transportation related facilities such as bus sops, walkways, crosswalks etc. and satisfaction level for these facilities are performed
In order to use SEM, firstly statistical reliability for the surveyed data is analysed and then latent variables can be derived by using a Confirmation Factor Analysis. The results show that facility service and satisfaction level has a positive relationship as we assumed. The loading factor for three latent variables are bus stops(0.209), crosswalks(0.155) and walkways(0.024) in order. In terms of bus stops, the loading factor for bus stops are cube height(0.911), wheelchair area(0.736) and message board position(0.596) in order. The bus stop is the most influential facility for the satisfaction of disabled people in Yesan-City. Among the bus related facilities, the cube height is the most influential facility factor for the disabled people satisfaction.
