Deliver advanced traveler information services

As the complexity of the requirements for advanced traveler information systems (ATIS) continues to grow, the research towards better and faster development of ATIS is gaining increasing attentions. However, two issues on the delivery of services remain to be addressed: 1) how to quickly build a flexible ATIS to incorporate services that reside in the extant software; and 2) how to perform complex services on the devices of limited resources like on-board PCs. In this paper, we propose a service delivery mechanism based on Web services and agent technology to alleviate these issues. Based on the proposed mechanism, a flexible and extensible ATIS can be developed and its services can be delivered in a systematic manner.
