Abstract:
The steady-state dynamics of a two-channel TASEP coupled with Langmuir kinetics in the
presence of a localized bottleneck are investigated under a fully asymmetric lane-changing rule. A
hybrid mean-¯eld approach is adopted to generate the density pro¯les as well as phase diagrams.
The e®ect of lane-changing rate and strength of bottleneck on the stationary dynamics of the
system has also been investigated. It is observed that an increase in lane-changing rate weakens
the e®ect of bottleneck. As a part of studying the shock dynamics, we have identi¯ed and analyzed
turning e®ect in the movement of shock with respect to lane-changing rate. Our theoretical
arguments are in good agreement with extensively performed Monte-Carlo simulations.
