Results
TUD Dresden University of Technology has completed the city-specific analyses of the data collected from the 11th iteration of the SrV time series study. These results have been available to the commissioning institutions since November 2019.

Results of SrV 2018
Cross-city trends and key findings from the 2018 survey are summarized in the following presentation:
SrV 2018 – Presentation of Results
The SrV City Comparison measures and compares the key indicators of travel behavior of the residential population for the participating study areas. This makes the range of variation of the surveyed parameters for the SrV study areas visible. At the same time, the document enables direct comparisons between the participating cities and districts as part of a benchmarking process. In order to properly interpret the findings from these comparisons, the specific local conditions of the compared cities need to be taken into account.
The tabulation of the 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 reference 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
Mobility Fact Sheet Tabular Report - Lower-order centers/rural municipalities; topography: hilly
Mobility Fact Sheet Tabular Report - Middle-order centers; topography: flat
Mobility Fact Sheet Tabular Report - Middle-order centers; topography: hilly
Mobility Fact Sheet Tabular Report - Higher-order centers with fewer than 500,000 inhabitants; topography: flat
Mobility Fact Sheet Tabular Report - Higher-order centers with fewer than 500,000 inhabitants; topography: hilly
Mobility Fact Sheet Tabular Report - Higher-order centers of 500,000 or more inhabitants (excluding Berlin); topography: flat
Mobility Fact Sheet Tabular Report
The second classification scheme is mainly used for the presentation of cross-city results and is suitable for longitudinal analyses. As seen previously in SrV 2013, the following three city groups were formed:
- SrV Large Cities East
Mobility Fact Sheet Tabular Report - SrV Large Cities West
Mobility Fact Sheet TabularReport - SrV Large Cities Combined
Mobility Fact Sheet Tabular Report
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. Further explanations regarding the city groups can be found in the Tabular Reports.
The SrV 2018 Methodology Report provides a comprehensive description of the survey methods used in this project. The questionnaire is documented in the appendix. The report on non-response analysis and weighting supplements the Methodology Report with key details.
