An Examination of Overtaking Judgments Based on Limitations in the Human Perceptual System: Implications for the Design of Driver-Assistance Systems - Digital Signal Processing for In-Vehicle Systems and Safety - page 234

Fig. 17.1 A model for designing driver-assistance systems to overcome perceptual limitations in
drivers
allocating more attention will not improve driver performance. Therefore, DAS can
contribute significantly toward enhancing the effectiveness of visual information
which will lead to better perceptual judgments, reduce collisions, and increase
driving safety.
17.7 Conclusions
The global data on overtaking accidents suggest that such traffic maneuvers require
immediate attention. Additionally, the limitations in the human perceptual system
suggest that drivers' judgments are not always accurate while performing such
maneuvers. Therefore, it is important to design DAS that can aid the drivers during
these complex maneuvers. Current FCAWS are typically designed for rear-end
collisions. However, the visual information and environmental characteristics
involved in a car-following task is different from an overtaking maneuver. In
short, it is important to design DAS that can help drivers during overtaking
maneuvers. Also, I have identified seven functional requirements that are important
to consider in the design of such DAS. Finally, a model has been proposed for the
