This dissertation addresses the question of how the quality of household travel surveys can be determined, evaluated, and ensured for the development of future surveys. The willingness of individuals to participate is an important, but by no means exclusive, indicator of quality. A central research question of this work deals with the concept of combining group-specific survey methods to increase survey quality. Beginning with some fundamental terminological considerations, this work then focuses on essential design elements and, in particular, sources of error in surveys in empirical social research in order to establish various approaches for assessing the quality of a survey. Building on this, household travel surveys are introduced in specific examples, and approaches for quality assurance in such household travel surveys are compiled. A comparison of design elements and possible errors in household travel surveys provides for the identification and description of nine areas of activity. In the context of findings from the surveying practice as well as experience in conducting several waves of the research project 'Mobility in Cities – SrV', the extent to which the respective fields of action can contribute to the reduction of errors and to quality assurance was assessed. On this basis, concrete options for action were selected. In order to evaluate the courses for action in terms of their effectiveness in securing and increasing the quality of surveys, a total of 24 quality indicators were compiled on the basis of extensive literature review. These allowed for the systematic assessment of three areas: quality of collection, content, and of application. With the involvement of analysis groups and quality indicators, a detailed empirical analysis was carried out to examine the extent to which the selected courses for action are suitable for group-specific combinations of survey methods and whether this can increase survey quality. In addition to extensive group comparisons, a survey simulation was implemented using the Monte Carlo method. The data foundation for these analyses primarily consisted of the surveys carried out for the research project 'Mobility in Cities – SrV'. These analyses enabled the establishment of recommendations which further the development of household travel surveys; these were divided into a cross-group section as well as a section for specific groups. Prior to these recommendations, it became clear that for future household travel surveys, only one individual in the household should be questioned regarding their trips on specific reference days. This decision significantly facilitates the future implementation of (even more selective) group-specific approaches. The compiled recommendations provide a consistent, practical foundation that can be applied to other surveys in order to adapt the design of existing and future household travel surveys, thus providing an overall or at least partial implementation of group-specific approaches which can improve overall survey quality.
