Abstract:

In order to reveal the domino effect resulting from the vehicle queuing, a determination model of vehicle queuing location is constructed based on the kinetic start-stop wave model, which can real-timely decide the head location, the end location and the length of any queue in a traffic network. Then, according to the model and the correlation among vehicle flows, two random neighbor intersections in 10 conditions are taken to reveal whether the downstream flow blocks the upstream flow or the conflicted flow and further results in the domino effect. The results demonstrate that the coupling of vehicle queues on neighbor segments constitutes the core of the domino effect in a traffic network.

Key words: traffic conflict, congestion, jam, vehicle queuing location, domino effect
