Title Assessing Effects of Mixed-Mode Design in a Longitudinal Household Travel Survey
Year 2017
Access date 14.07.2017
Abstract The German Mobility Panel (MOP) is a national household travel survey that has been collecting data on the travel behavior of the German population since 1994. One of the MOP’s central assets is the ability to provide time series data on travel behavior. Thus, the comparability of survey results from different years is a mayor objective on the survey method used. Within the last decade declining survey participation rates amongst different socio-economic groups resulted in the need to implement a mixed-mode design of the MOP in 2013, both for the sampling stage (landline and mobile phone recruitment) and in the data collection stage (paper and web). The authors analyze whether the adaptations in survey modes do affect the survey results and if so why. Ideally, the authors have increased the representativeness of the MOP. However, measurement biases because of the mixed-mode design are also conceivable. For the decomposition of survey mode effects the authors applied the propensity score weighting method. This method aims to impute the hypothetic responses participants would have given under different survey modes; disparities between actual responses and potential outcomes under another mode are traced back to the mixed-mode design. The authors' analyses indicate that trip rate biases on shopping and leisure trips and on short trips are partly caused by the mixed-mode design; quantities in time spent in the transportation system and trips made by car and public transport and commuting trips are barely biased.
