This paper presents a task model and task ontology based on travelers’ tasks, and an intelligent tourist information service system using them. With the recent advances in Internet and mobile technologies, there has been an increase in the use of intelligent tourist information services via the Web and mobile systems. In addition, many ontologies have been introduced in tourist domain to provid...
With the generalization of real-time traveler information, the behavior of modern transport networks becomes harder to analyze and to predict. It is now critical to develop simulation tools for mobility policies makers, taking into account this new information environment. Information is now individualized, and the interaction of a huge population of individually guided travelers have to be tak...
TRAVELER ARRIVALS WORLDwide exceeded 800 million in 2005. Today’s mobile populations and global economies lead to extended stays for many travelers. For long-term travelers visiting malaria-endemic countries, recommendations for prevention have been difficult to standardize due to the diversity of long-term travelers and their itineraries, the variation in quality of and access to medical care,...
In a stochastic roadway congestion and pricing model, one scheme (omniscient pricing) relies on the full knowledge of each individual journey cost and of early and late penalties of the traveler. A second scheme (observable pricing) is based on observed queuing delays only. Travelers are characterized by late-acceptance levels. The effects of various late-acceptance levels on congestion pattern...
