Applicability of microscopic shockwave theory for evaluating collision risk in vehicle platoon

In this study, an applicability of microscopic shockwave (μSW) theory is evaluated whether it is efficient in assessing the risk of rear-end collision in vehicle platoon. Two different types of μSW behavior are proposed for the evaluation; one is the car-following that shows a higher risk, whereas the other is a low-risk vehicle platooning. The numerical analysis attempts to evaluate whether the conventional risk evaluation approaches are able to distinguish those two cases; high and low risk platooning based on the proposed μSW technique. The statistical analysis showed that the behavior of μSW is capable of assessing the risk of rear-end collision of platooning vehicles.
