**Introduction**
|
|
|
The Smart Mobility and Tourism (SMT) use case has been implemented in cooperation with the industrial partner from the Genoa city (Italy). The main scope of the SMT use case is to realize a Collaborative Travel Agent System (CTAS) through the cooperation of several content and service providers, organizations and authorities publicly available in Genoa. The SMT use case involves a mobile application as an "Electronic Touristic Guide" that exploits CTAS in order to provide both smart mobility and touristic information.

The use case starts with the mobile application **STApp** detecting the current position of the user, and asking for which type of point of interest to visit and which type of transport mode to use. From this information, **Tourist Agent** initiates two parallel flows in order to retrieve the information required by the "Electronic Touristic Guide". In particular, the left-most branch retrieves smart mobility information according to the selected transport mode, while the right-most branch gathers touristic information. Finally, the two parallel flows are joined together to produce the data needed for the "Electronic Touristic Guide". Finally, the guide is shown to the user by means of **STApp**.
