Analysis of the Wiedemann Car–Following Model over Different Speeds Using Naturalistic Data

This research effort analyzes the Wiedemann car-following model using car-following periods that occur at different speeds. The Wiedemann car-following model uses thresholds to define the different regimes in car following. Some of these thresholds use a speed parameter, but others rely solely upon the difference in speed between the subject vehicle and the lead vehicle. The results show that the thresholds are not constant, but vary over different speeds. Another interesting note is that the variance over the speeds appears to be driver dependent. The results indicate that the drivers exhibit different behaviors depending upon the speed which can imply an increase in aggression at particular speeds.
