Seepage of Smaller Vehicles under Heterogeneous Traffic Conditions
Agarwal, Amit; Lämmel, Gregor
In the direction of complex heterogeneous traffic modeling, the present study proposes a model to simulate the behavior of smaller vehicles in the congested regime called seepage action. As the name suggests, in congested part of links, smaller vehicles like motorbikes and bikes do not stop at the end of queue. Instead, they move continuously across the gaps between the stationary congested vehicles and come in front. This behavior is rarely modeled and quantified even though it is common praxis in most of the developing nations. In order to facilitate this behavior, a state of the art queue model is modified to allow for seepage in congested regime. Furthermore, the concept of backward traveling holes is introduced. Thus, the congested branch of the fundamental diagram is modeled more realistic.
