Improving the quality of public transport services can produce a modal shift towards this more sustainable modes of transport. In this research and using data from customer satisfaction surveys, we applied decision trees for analyzing the service quality of the metropolitan public transport of Granada (Spain), in order to define transport strategies that leads towards a higher level of quality of the service and, conse-quetly, more satified passengers.
