Comparison of community response to road traffic noise in japan and sweden --Part II Path analysis
Journal of Sound and vibration, (2002)
Abstract
Path analysis was applied to data obtained in social surveys in Kumamoto
and Sapporo, Japan, and Gothenburg, Sweden, to cross-culturally compare
the causal models that describe the multiple stratum relationships
between road traffic noise annoyance and endogenous and exogenous
variables. Path models can estimate not only the direct effect of
a variable on annoyance but also the indirect effect of the variable
via other variables. The exogenous variables were selected from housing,
personal and environmental factors, and the endogenous variables
were selected from various activity disturbances and related effects,
based on the results of correlation coefficients between variables
and discrimination by factor analysis. An a priori path model was
constructed at the start of the analysis and the structure equations
for the endogenous variables were formulated. The standardized partial
regression coefficients are called path coefficients and show the
strength of the linkage between variables. A revised path model was
constructed by deleting insignificant paths. The characteristics
of annoyance responses were as follows: (1) annoyance caused by exhaust
has the strongest relation to noise annoyance and (2) structures
of noise annoyance were different between Japan and Sweden and between
housing types, probably owing to differences in lifestyle.
