INITIAL ON-THE-ROAD TESTS OF DRIVER INFORMATION SYSTEM INTERFACES: ROUTE GUIDANCE, TRAFFIC INFORMATION, IVSAWS, AND VEHICLE MONITORING. FINAL REPORT

The purpose of these experiments was to examine the safety and ease of use of simulated driver information system interfaces and to provide data that might be used to certify those qualities. In the first experiment, 6 pairs of drivers (12 participants) drove an instrumented car over a 19-turn, 35-minute route aided by an experimental route guidance system. The route guidance was provided on a head-up display (HUD), on the instrument panel (IP), or by voice. Drivers also used the other three information systems. The purpose of this experiment was to discover flaws in the driver interface or test protocol that were so serious that the experiment could not continue. There were none. In the second experiment, 43 drivers followed the same route using the same route guidance system and other information systems. Drivers made very few turn errors (mean = 1.8), with the fewest for the HUD, followed by the IP and voice designs. Also considered were measures obtained from the instrumented car including the mean and standard deviation of steering wheel angle, throttle position, speed and lane variance. There were very few differences among the three route guidance interfaces. Eye glance durations and frequencies were also obtained, as well as ratings of safety and ease of use of the driver interfaces.
