摘要：

We analyze the origin and characteristics of the bottleneck-induced shock in a two-channel totally asymmetric simple exclusion process with Langmuir kinetics under symmetric coupling conditions. The variation in height of the spike, which has been found to be a precursor to the bottleneck-induced shock, is analyzed with respect to lane-changing rate Omega and bottleneck rate q. The critical value of q(q(c)), below which the effect of bottleneck turns from local to global, has been identified. A non-monotonic variation of qc with respect to Omega is observed. The bottleneck-induced shock exhibits turning effect with respect to an increase in Omega. (C) 2016 Elsevier B.V. All rights reserved.
