Cost-based Evaluation of Transport Survey Improvement Techniques

Abstract

Besides respondent incentive articles (RIA), there are many possible measures to increase response rate and improve accuracy in transport survey. This study proposes that performance of those measures can be evaluated based on the survey cost which satisfies given accuracy level. The proposed criteria can be applied for the technique which alter the response rate or accuracy unevenly for seleral sub-groups of the population. A case study of a shopping travel survey held in a shopping district in Hiroshima City practically illustrates the effectiveness of the RIAs, based on the proposed criteria.
