In this paper, the authors introduce an In-Vehicle Information System (IVIS) which will manage messages from a variety of Advanced Traveler Information Services (ATIS) devices which can be installed in a road vehicle. The IVIS serves as the interface between the driver and the driving environment. Increasingly, after-market systems, such as routing and navigation aids, are becoming available which can be added to vehicles to aid in travel and/or the conduct of business in the vehicle. The installation of multiple devices, each with its own driver interface, increases the likelihood of driver distraction and thus the risk of an accident. The goal of this project is the development of a fully-integrated IVIS which will filter, prioritize and display highway and vehicle information safely and efficiently. Such a system, using modern digital technology, will tailer information both to the driver's needs and to the driving environment. A variety of other efforts, both in the U.S. and abroad, either have been completed or are nearing competion, and the results of these efforts will be incorporated into this present system. IVIS must perform three high level fuctions. It must 1) interact with (ATIS) subsystems, 2) manage information, and 3) interact with the driver. To safely develop and evaluate such a device, a platform must be devised which permits testing in an off-road setting. The development and testing of an IVIS is proceeding along two lines. First, a computer nework has been built which emulates the functioning of various ATIS devices that send information management to a PC, which serves as the IVIS. The IVIS PC serves as the device on which the information mnanagement logic is developed and tested. The second line of development is dual-task platform on which to develop and evaluate the driver interface - both for display and for control input. The platforms to carry out this work are described, along with the plans to integrate actual ATIS subsystems into the platform. |
