Scenic Athens: A Personalized Scenic Route Planner For Tourists

Several mobile guides for unknown destinations provide assistance to tourists (through personalized tour recommendations) in making feasible plans and visiting the most interesting POIs within their available time. However, existing tourist tour planners only regard available attractions as sites lacking physical dimensions (i.e. POIs are treated as points). Although this is adequate for scheduling visits at POIs with single entry/exit points, it fails to capture practical properties of typical tourist visiting styles in urban destinations (e.g. tourists typically enjoy walking on pedestrian zones, market areas and scenic neighborhoods). Herein, we introduce Scenic Athens, a context-aware mobile city guide for Athens (Greece) which delivers personalized tour planning services to tourists deriving near-optimal sequencing of POIs along recommended tours. Scenic Athens takes into account a multitude of travel restrictions and POI properties, also incorporating scenic (walking) routes (in addition to point POIs), thereby supporting more experiential exploration of tourist destinations. A user evaluation study validated the recommendation value, usability and perceived utility of the proposed application.
