Test Planning, Analysis, and Evaluation System (Test PAES): A Data Archiving Tool for Engineers and Scientists 970453

As Intelligent Transportation Systems (ITS) become more prevalent, the need to archive data from field tests becomes more critical. These data can guide the design of future systems, provide an information conduit among the many developers of ITS, enable comparisons across locations and time, and support development of theoretical models of driver behavior. The National Highway Traffic Safety Administration (NHTSA) is interested in such an archive. While a design for an ITS data archive has not yet been developed, NHTSA has supported the enhancement of the Test Planning, Analysis, and Evaluation System (Test PAES), originally developed by Calspan SRL Corporation for the U. S. Air Force Armstrong Laboratory, for possible use in such an archive.
On a single screen, Test PAES enables engineering unit data, audio, and video, as well as a vehicle animation, to be time synchronized, displayed simultaneously, and operated with a single control. A time line depicts data that are loaded on the system. Dynamic windows display engineering unit data. Vehicle animations provide two perspectives (side and aft) and are driven from the state-data of the vehicle. Multi-media windows can display up to four videos. The Test PAES type of integrated display allows interested individuals to view the different forms of data together and perform crosscutting analyses to determine the effectiveness of ITS.
