| Outline of Final Research Achievements |
The purpose of this study is to construct a causal model for living environment evaluation caused by transportation noise and vibration. A social survey for living environment along Nagano Shinkansen railway were conducted by mail method in 2013. Target detached houses were selected in the range of up to 100m vertically from the rail of near side. The sample size was 294, and the response rate was 45%. The response of male was 60%, and about 80% were 50 years old or more. Noise exposure level for each house was estimated the prediction formula by Nagakura and results of field measurements in October. It was shown that respondents of about 16% responded "very" or "extremely" annoyed at 70dB (LASmax) using logistic analysis. A causal model was constructed by using this survey data. Fit indexes of this model were 0.951 at CFI and 0.074 at RMSEA. This result is fairly good, but it is possible that this model can be improved by further considering the significance of the path in the model.
