In addition, because of the characteristics of control charts, including individual differences and monitor in time, control charts are well suited for adoption in car-following behavior evaluations. We conducted a simulator experiment to investigate 48 high and 48 low driving anger drivers’ driving performances, subjective questionnaire ratings, and divided attention (DA) response tasks under both simple and complex driving conditions when FCWs are presented by five-stage, X-bar control charts or X-bar and exponentially weighted moving-average (EWMA) chart interfaces. The results show that high-anger drivers drive maintain shorter time to collision and headway than low-anger drivers, and FCWs provided a substantial benefit, particularly FCWs using X-bar control chart. The user experiences of FCWs improved the response time of braking, decreased the maximum longitudinal deceleration, and expanded the minimum TTC and headway with the lead vehicle, particularly the user experiences of FCWs using X-bar control chart. The implications of these results are important to the designers of FCW systems.
