BEHAVIOUR OF A GROUP OF DRIVERS IN EMERGENCY SITUATIONS

VERHALTEN EINES FAHRERKOLLEKTIVS IN NOTSITUATIONEN

The behaviour of car drivers with respect to braking and steering in critical situations can be recorded for future evaluation with the appropriate apparatus. No large scale tests have been carried out to date. Emergency situations were simulated on the Daimler-Benz works test track with the aid of pedestrian type dummies of foam rubber. They were hidden from the oncoming drivers and were made to appear suddenly by means of wire rope gear. The behaviour of the drivers was determined by recording the steering angle, braking pressure, throttle, pedal travel, and the movement of the vehicle by measuring longitudinal and transverse acceleration and speed. Reaction times were measured in two groups of test drivers numbering 22 and 27 persons respectively, who were not aware of the test programme. The average values are about 1,3 seconds. There is no significant difference between men and women. The values are dependent on the circumstances. (TRRL)
