Mix effect model on the relation between braking pedal velocity and physiology

It is necessary to ensure the traffic safety to predict the driver behavior by analyzing the physical &psychology. Eight drivers were selected with age between 35 to 48, Electrocardiograph, Frecord data collecting system and dynamics GPS were utilized to study the drivers' behavior under emergency in the Transportation Communication Trial Field. The mix effect model between physiology and braking pedal velocity, which is affected by distance between the vehicles and the obstacle, driving velocity, driving time, personality and have influence between them, has been established. This can offer new method for the drivers' behavior analysis under emergency.
