The aim of these surveys is to find out the level of satisfaction of users with the services provided by the Tramway of Parla, in order to know the strengths and weaknesses of the system and to be able to improve those aspects necessary to offer users a higher quality service.  To this end, surveys were carried out with passengers both on board and at different stations between 6.30 a.m. and 8.30 p.m.

This campaign was also accompanied by a mystery shopping campaign to analyze the behavior of the operating personnel of the Parla Tramway: drivers, inspectors, customer service and PCC operators, using the mystery customer technique, which was carried out during the months of September and October.
