Instead of joining a package tour, many people become backpackers and choose self-guided travel for many reasons, especially when it is much easier to find travel information nowadays. Thus, many social websites are popular now for backpackers. We noticed that the issues discussed in those websites can be classified into three major types: making a travel plan before departure, asking for instant help on the journey, and sharing experiences after home. After searching related travel information and making a detailed travel plan, one usually writes or prints the plan on a small and portable paper notebook for reference on the journey. However, it is inconvenient to look up specific information in the paper notebook. In this study, an integrated e-tourism service for self-guided travel, named IEBSR, is presented. IEBSR consists of four major components: (1) a web-based itinerary editor where a user can make a complete and detailed travel plan, (2) an itinerary browser app for smart mobile devices in which a user can easily browse her travel plan anytime and anywhere, (3) an itinerary sharing and discussion subsystem, and (4) an itinerary recommendation subsystem. IEBSR integrates with Google Maps and other travel information systems. Thus, users can edit their travel plans intuitively on the map. They can easily and quickly browse the information recorded in a travel plan in the app based on the GPS location information sensed by their smart mobile devices. With itinerary sharing and recommendation, they can customize a proprietary travel plan from an existent one. Experiment results have successfully demonstrated that the proposed integrated e-tourism service can help backpackers significantly.
