ATLAS: A World-Wide Travel Assistant Exploiting Service-Based Adaptive Technologies.

Nowadays, users can count on a large amount of mobility services offering disparate functionalities and providing all needed information. Yet, from a user perspective, properly exploiting the available mobility services to organize journeys meeting personal expectations, is becoming a complex task. Indeed, discover and select the appropriate services in an open and constantly expanding domain, is a challenging and time-consuming task. We claim that a uniform and easy way for exploiting these services while moving around, getting accurate and personalized information is still missing. In this paper we propose a platform for the definition of value-added mobility services by (i) enhancing interoperability among the existing services, (ii) supporting their execution via run-time adaptation, (iii) through the definition of multi-channel front-end applications. On top of the platform, we have implemented and evaluated a world-wide travel assistant.
