Title: A new method of social survey on transportation noise using the Internet and GIS
Abstract: Up to now, two ways of fulfilling social survey have been mainly used in Japan; one is a face-to-face interview in which investigators visit individual households and the other a questionnaire survey by mail. In both cases, noise exposure levels at respondents’ locations have been estimated using results of field measurements. Needless to say, such methods are in general expensive, and methodological limitation has prohibited us to collect a sufficient amount of survey data from much wider areas. Technical innovation has, however, made us possible to invent a new method of social survey, in which we perform questionnaire surveys through the Internet (we call it as web-based questionnaire survey in the following) and estimate noise exposure levels at locations of individual respondents by applying the GIS database and noise calculation models. Respondents to the web-based questionnaire survey were invited via several means including posting, handbill distribution and recruitment on the Internet. This method not only enables us straightforwardly to establish a dose-response relationship based on a large volume of human responses from a wide area or without ristriction of survey area, but also permits us to calculate the population exposed to certain levels of noise exposure by combining census data with the GIS information. METHODS The newly developed method of social survey consists of a web-based questionnaire survey and a noise exposure estimation using the GIS as is shown in Figure 1.
