AUTOMOBILE BRAKING RESPONSE SPEED: AGE DIFFERENCES AND EFFECTS OF COLLISION WARNINGS
To examine age differences in emergency braking response times and the benefit of collision warnings, 18 older (age=74 yrs) and 29 young (age=26 yrs) licensed drivers completed four tasks in an automobile driving simulator. Participants attempted to brake as quickly as possible in response to braking of a car in front of them and to auditory and visual collision warning signals. Braking responses were made when the participant's car was stationary, traveling on an empty road, following at a comfortable distance, and following very closely the car in front of them. Participants also completed three laboratory reaction (RT) and movement (MT) time tasks to investigate age- and sex-related differences in the relationships of laboratory task performance and emergency braking responses. Results showed that the presence of collision warnings improved response times dramatically, especially for older drivers when following closer than comfortable.
