The application of internet based surveys in the Lisbon Metropolitan Area

Novembro 2011

This paper describes three web based surveys developed and conducted recently in the Lisbon Metropolitan Area for the development of two research projects in the MIT-Portugal Program (SCUSSE and SOTUR). The first survey was a stated preference survey regarding the mode choice assessment for innovative intermediate transport modes devised in the SCUSSE Project. The other two surveys consisted on data collection regarding residential choice (past and current), residential satisfaction and stated neighborhood preferences, connected with regular mobility patterns and accessibility levels. The first survey, needed to be programmed whereas the other two used commercial web software platforms. The objectives of this paper are manifold. It aims to compare the application of different surveying techniques (Web based and CAPI) and how they can be used to reduce costs and at the same time increase the overall responses quality while controlling for sampling biases. The second objective is to compare the accuracy levels in the answers of both techniques. Other objectives involve a detailed assessment of the evolution of response rates in the web based applications. These are related with the implemented dissemination strategies, in order to analyze its impact on the curve of the response rate. The paper also analyzes the variance in time required to complete the surveys, , the number of responses with the same IP address and the attrition rates for each component of the surveys. The paper concludes with a discussion of the obtained results, lessons learned and recommendations for future surveys.
