The target audience for the pedagogical product Urbax comprise those who want to acquire a holistic understanding of urban planning and development, for example, postgraduate students, local authority officers, elected representatives, practitioners. They must already have some notions through professional practice, post graduate studies or electoral mandate.

The number of participants is normally 12 to 18.

If possible, it is interesting to have a mixture of participants (for instance, private and public agents).

A session takes two or three consecutive days and should preferably not be split into several time spans in order not to break the continuity of the role game.
