One of the significant factors constantly monitored by a vehicle driver while driving is the behavior of the preceding vehicle. A person driving a vehicle, while observing the vehicle directly in front of them, tries to adjust their speed to the speed of the predecessor and maintain a safe distance from it. This distance ensures that the driver can stop the vehicle without causing a collision. This paper compares experimental measurement results with the results of modeling the movement of a vehicle following another in road traffic. Several commonly used safe-distance models were selected for comparison.Among all traffic flow models, microscopic traffic models constitute the largest group. The classification of microscopic traffic models is usually carried out based on the way the following process is implemented, i.e., the behavior of a vehicle while driving behind another vehicle, the leader. In the group of car-following models, one can distinguish: stimulus-response, safe-distance, and psychophysical models [1,2].
Stimulus-response models use the concept of describing a vehicle in a flow based on the principle of reaction to a stimulus. The stimulus for changing the movement strategy of a single vehicle is the occurrence of a speed difference in relation to the preceding vehicle. (…)
