Abstract
Sensitivity and response for car followers is known from the speed and acceleration of the vehicle that follows the vehicle in front of it. The study was conducted using a test vehicle equipped with a hidden camera and operated with the IonRoad Augmented Driving Professional program. To determine the difference in sensitivity, vehicle test is installed with a warning sign that has been previously designed. The study was carried out vehicle test on the traffic flow on the arterial road and collector road with two conditions. First condition, the vehicle test was installed a warning sign on the back and the second condition the vehicle test uninstalled the warning sign. The relative speed and relative distance for each time unit between the vehicle test installed and uninstalled warning sign with the follower vehicle show a significant degree of difference. So it can be concluded that the installation of warning sign material on the back of the vehicle test affects the sensitivity of follower vehicle.
