ABSTRACT
This chapter examines the problem of urban transport in the context of the "tragedy of the commons" model through a detailed study of drivers' attitudes and behaviors in Madrid, Spain. It explores the application of this model to the sustainability of urban transport from the results of a comprehensive survey carried out in Madrid, Spain. Sampling quotas according to sex and age for each of the 21 districts of the city were established from data from the Spanish Transport Administration, which show that that in Madrid there are 20 percent more male drivers than female. The chapter presents some basic data from the survey to provide an image of the individual driving patterns. It evaluates the validity in the Madrid traffic case of the main strategies from psychosocial studies to solve social dilemmas. Intervention in traffic problems as a part of the behavioral solution includes limiting private car use.
