Driver Behavior in Highly Critical Situations

The following reactions in this situation are possible in general  

Key findings include the time of driver reaction with respect to the system action, the TTC at the activation of the brake pedal, the time between the acoustical warning and the activation of the brake pedal, and the maximum deceleration. In addition the perception of the different warning signals by the drivers was investigated. 

These numbers indicate that there is no difference in the result due to the experimental conditions. The impact speed cannot be evaluated due to low number of collisions. The distance to the pedestrians in all avoided collisions is comparable for both
