An in-vehicle information system for its information management

This paper presents an In-Vehicle Information System (IVIS) research and development facility to investigate management of messages from Intelligent Transportation System (ITS) Services. These services include navigation and route guidance systems, real-time traffic management, and non-ITS devices such as cell phones and pagers, as well as other information to be presented to the driver. The introduction into road vehicles of multiple information sources related to the ITS raises issues concerned with driver distraction and cognitive overload, as well as problems which stem from dealing with multiple device interfaces. The IVIS serves as the interface between the driver and all the information sources, including both input from and information display to the driver. However, introduction of an IVIS raises a number of issues which relate to things such as proprietary messages, message prioritization across devices from different manufacturers, and safe access to the vehicle manufacturer's proprietary data bus.
