152 Ergonomics in the Automotive Design Process
5. New signal functions: Besides the presence, parking, stop, and turn information, signal
lamps based on new technologies have the potential to provide additional information to
other drivers. Thus, some future application issues are
a. A new “stopped vehicle signal” may have the potential to reduce rear-end collisions.
b. Improving effectiveness of stop lamps by incorporating a “stopping” vehicle signal
that provides information on the rate of closure during stopping (i.e., providing infor-
mation about the level of lead vehicle deceleration).
c. Displaying state of other decelerating devices (e.g., retarders on heavy trucks, vehicle
stability control systems).
d. Displaying other ...
