Results of SrV 2013
The tabulation of the city-specific results of the SrV 2013 survey has been completed. The results have been available to the commissioning institutions since October 2014.
The SrV City Comparison contrasts key indicators of the travel behavior of the residential population for the different participating study areas. This allows users of the results to understand the range of variation in the indicators collected for the SrV cities. It also makes direct comparisons with other cities possible. However, such comparisons are only meaningful if the specific local conditions of the respective cities are taken into account.
The tabulation of cross-city results makes it possible to analyze combinations of characteristics in a more differentiated way than in the standard tables for individual cities. This, in turn, yields results that would not be statistically reliable for an individual city. Mobility indicators for city groups also provide cities that did not participate in the SrV survey with referene values for typical characteristics of travel behavior in their own municipality.
The first classification scheme is primarily based on modeling-related considerations and represents a cross-sectional analysis of the current survey iteration. Since the composition of these city groups varies depending on the participating municipalities, they are not suitable for analyzing trends over time. Based on the characteristics of centrality according to central place theory (which classifies municipalities according to the services they provide for surrounding areas), population size, and topography, seven city groups were formed:
Lower-order centers/rural municipalities; topography: flat
Middle-order centers; topography: flat
Middle-order centers; topography: hilly
Higher-order centers with fewer than 500,000 inhabitants; topography flat
Higher-order centers with fewer than 500,000 inhabitants; topography: hilly
Higher-order centers of 500,000 or more inhabitants (excluding Berlin); topography: flat
The second classification scheme is mainly used for the presentation of cross-city results and is suitable for longitudinal analyses. Within this scheme, there are three groups of participating cities:
SrV Large Cities East represents the oldest SrV city group. Reflecting the historical division of Germany, this group has formed the basis for analyses of long-term developments in travel behavior in large cities in former East Germany since 1972. SrV Large Cities West comprises large cities in former West Germany that have participated continuously in the SrV survey since at least 2008. SrV Large Cities Combined comprises the cities from both groups, SrV Large Cities East and SrV Large Cities West.
The SrV Methodology Report provides a comprehensive description of the methodology of the survey. The appendix contains the questionnaire. The reports on data preparation and on non-response analysis and weighting supplement the Methodology Report with key details.

Key findings, cross-city trends, the scientific background, as well as experiences from the fieldwork were presented and discussed in front of more than 120 participants at the final conference on November 10 and 11, 2014. The papers presented at the event can be downloaded from the page on the final conference.
