Ubiquitous travel environments and travel control strategies: Prospects and challenges

In the near future, ubiquitous travel environments in which travelers have direct access to information and communication technology will become widely available. In principle, it will allow various organizations and companies not only to provide real-time dynamic information but also to induce travelers to behave in ways that contribute with some underlying personal or system-wide objective (e.g. avoid risk, environmental concerns etc). The latter application assumes a sufficiently valid and reliable model of traveler response to information provision or recommendation. As these two fields have mainly developed in isolation, the purpose of this chapter is to provide an overview of the state of the art of these two fields.
