Multiple previous studies at international level have examined the effects of land use policies regarding to sustainability, and particularly devoted to the induced private car mobility excess. However, it is remarkable the different urban planning tradition depending on the country or region. Thus, the Mediterranean urbanism has been generally featured by high or moderately high population and dwellings density, which has promoted the presence of pedestrians on streets. In this paper we analyse the case of Burgos city, as an example of mid-sized city in Spain. Although it isn't suffering sprawl symptoms, its local administration is trying to improve current modal share by increasing sustainable means of transport. The performed analysis includes population, dwellings density and absolute compactness, to check their influence in car trip generation. In coherence with previous studies, our results have shown a qualitative correlation between low densities and higher use of private car for the studied case. The effects of some urban planning policies are discussed as possible reasons of observed behaviour, serving as basis for future recommendations.
