We study the traffic states and queuing occurring in traffic flow on a toll highway with multi-lane tollgates. The traffic states change with increasing density and varying number of tollgates. When the manual-collection vehicles sort themselves into the tollgates, the queues occur just in front...

We study the traffic states and jams occurring in traffic flow on a two-lane toll highway with electronic and manual (traditional) tollgates. The electronic and manual collection vehicles sort themselves into their respective lanes at low density, while they mix at each tollgate at high density....

In this paper we review some recent results obtained in [F. den Hollander et al., Metastability and nucleation for conservative dynamics, EURANDOM report 99-025, J. Math. Phys. (2000), to appear] on metastability and nucleation for the two-dimensional lattice gas with Kawasaki dynamics at low...
