Issues on making neighborhoods walkable for the elderly has drawn wider attention in the process of aging. Considering the physical and mental characteristics of the elderly, walking activities are sensitively influenced by environmental perception, like the satisfaction of walking environment and necessity of walking activities. The aim of this research is to find out the key environment factors which influence the perceived assessment in the elderly’s walking.
Based on 21 neighborhoods cases in central Shanghai, method of questionnaire survey (n=1365) was employed to get the elderly’s assessment of walking environment. The measures of physical environment factors, including the aspects of urban fabric, land utilization, interface form and walking facilities, were collected by site observation and GIS database. Correlation and multinomial logistic regression analysis were taken to find out the key variables which are associated with perceived assessment.
It was found that environmental factors such as width of sidewalks, density of commercials, population density and presence of transparent boundaries have influences on the elderly’s environmental satisfaction assessment. While the scale of the neighborhoods, density of commercials, presence of education facilities, width of sidewalks are related to the necessity evaluation of the elderly’s walking activities. In addition, socio-demographic attributes like age, gender and income also have effects on the elderly’s perception of walking environment.
