Accessibility in the local food supply. A multidimensional conception, modelling and analysis based on empirical consumer surveys.
Final Report Abstract
Based on a mix of methods consisting of a household survey, statistical analysis, modelling and qualitative interviews, the question of the accessibility of grocery stores in the predominantly rural region of Main-Franconia was examined. In addition to the choice of shopping location, a particular focus was on consumers' perceptions, evaluations and preferences, taking into account various dimensions of accessibility. The survey allowed the identification of essential parameters for the choice of shopping location and a typification of consumers according to their shopping behaviour, preferences and evaluations as well as socio-demographic criteria. New findings have emerged, particularly with regard to the embedding of grocery shopping in everyday routines and chains of routes: above all, the high degree of car availability has led to the fact that spatial proximity starting from the place of residence does not have the importance attributed to it in previous research and practice. Based on the empirical survey results, a further methodological-technical aim was formulated: the development of models that combine spatial interaction models and GIS-based accessibility models. Various kind of models were developed and aligned with the empirical results. While classic accessibility models are often based on distance zones, the approach pursued here was to integrate actual shopping trips. This is particularly valuable for retail research, as the model is able to integrate not only pure distance factors but also demand-side preferences and opportunity costs. The combining of grocery shopping on the way to work, as determined in the survey, was taken up in a further GIS accessibility model approach along commuter routes. The model not only reflects everyday routines in shopping and mobility behaviour. It is also possible to make statements about the extent to which travel times are reduced compared to the usual accessibility and market area models, which always have the residential location as source and destination. The modelling results also help to explain why a larger proportion of respondents rate the food supply relatively highly (despite the objectively poor supply situation at their place of residence). The models open up possibilities for adapting retail location structures and developing local supply concepts. By enabling accessibility values to be transferred to larger areas, the models also provide a robust basis for spatial planning decisions.
