Abstract

A system for testing and evaluating driver situational awareness incorporates a device for displaying road and traffic images to a subject being tested, road and traffic image data for simulating operation of a vehicle to be outputted on the display device, instruction data to be outputted at least on the display device, input devices for inputting response data from the test subject in response to road and traffic image data generated on the display means, and a control device for controlling the operation of the system. The control device incorporates a vision test component for conducting a vision test of the subject and a driving reaction test component for conducting a driving reaction test of the subject. Each of the vision and driving reaction tests includes generating road and traffic image data for simulating operation of a vehicle, generating instruction data in coordination with the image data for providing instructions for the subject, monitoring for inputting of response data, and determining whether the inputted response data is correct or incorrect. The generated image data includes road and traffic video image data, test pattern image data and situation test image data. The test pattern image data is structured to test static visual acuity, static visual contrast sensitivity, dynamic visual acuity, dynamic visual contrast sensitivity and angular motion sensitivity. The situation test image data is structured to test divided attention capacity, selective attention capacity, attention switching, working memory functions, brake reaction time, and complex reaction time and decision making.
