Agent-based Drivers' Information Assistance System

`Drivers' Information Assistance System (DIA system)' is an ITS (Intelligent Transport Systems) application framework that provides agent-based information assistance to drivers through car navigation systems or on-board PCs. DIA system enables flexible information retrieval over the Internet using intelligent mobile agent, and incorporates a high-speed event delivery facility that makes real-time information service possible. The goal of the system is to provide up to the minute information and services related to driver needs, such as parking lot vacancy information. Crucial to making this a practical operation is the agent-based ability to access the network while the vehicle is in motion.
