INTEGRATED ATMS/ATIS SIMULATOR FOR HUMAN FACTORS RESEARCH

As part of the Federal Highway Administration sponsored research program for an Advanced Traffic Management Center Simulator, the Georgia Tech Research Institute (GTRI) has developed a test bed for interface concepts in Intelligent Transportation Systems. Operators are trained on the simulator to scan a series of simulated camera scenes for vehicle incidents and for congestion. Operators use a set of interface tools to select cameras, to transmit messages to central public safety dispatchers, and to post to variable message signs. The simulator includes an in-vehicle mock-up for testing Advanced Traveler Information System (ATIS) concepts. Presently, the authors are using a 32 monitor to display the out-of-vehicle point of view. The out-of-vehicle scenery includes digitized video taken from a moving vehicle on interstate highways and on surface streets. The drivers are asked to make decisions based on the out-of-vehicle scenes and on information presented via a simulated in-vehicle computer. The ATIS simulator includes a Silicon Graphics Indigo2 with a JPEG compression board to process the video. Digitized video presented at 30 frames per second allows real-time control of the video to be played based on decisions made by the driver. The decision making behavior of drivers is examined under heavy traffic conditions in conjunction with information presented to drivers via the in-car displays. The combined ATMS-ATIS simulation supports research on the interaction of the two primary components of an Intelligent Transportation System, including situations in which information provided by the ATIS conflicts with information disseminated by the ATMS.
