Understanding the structure of hyper-congested traffic from empirical and experimental evidences
High resolution, individual vehicle data from videos have been analyzed. An experimental study of car-following behavior has been carried out. The structure of traffic flow in hypercongested states has been studied. Our data contradict the existence of a Homogeneous Congested Traffic state. The instability mechanism of hypercongested traffic has been discussed.
