ENGINEERED VISIBILITY WARNING SIGNALS: AN IDEA PROJECT

This project centers on the development and testing of an integrated display of warning signals for the intelligent transportation systems (ITS) vehicles driver. Plans for the highway of the future predict as many as 12 new warning signals whose purpose is to alert the driver to incipient difficulties related to vehicle operation, proximity of other vehicles, driving conditions, and vehicle position. In this study, the optimal configuration of these signals at the driver's eye is explored. The aim of the study is to maximize detectability and identifiability of such signals while minimizing the time to react. Accumulated research in the human factors and vision literature points to a number of constraints and desirable properties that a warning signal display must satisfy. Using this work, plus known characteristics of the human visual system, a set of specifications for the warning signal display is developed. Specifications include temporal, chromatic, and spatial characteristics of the visual stimuli to be used as warning signals. A proprietary process is incorporated in the design that is thought to optimize both signal detectability and salience by supplying visual warning signal optimized for processing by the fastest and most sensitive nervous pathway in the human visual system. The project will rigorously test human performance with a display that satisfied these specifications and will provide the ITS community with a description of design constraints, an example of a design developed within these constraints, benchmark performance tests of it, and a means of evaluating future prototypes developed for commercial application.
