The effect of a temporary bottleneck in two-lane of a road on traffic flow based on the Kerner-Klenov-Wolf model

Considering a temporary bottleneck made by special accidents, we proposed a new two-lane traffic model based on the KKW (Kerner-Klenov-Wolf) model. According to the difference of driver behavior and vehicle type, we present a new asymmetry lane-changing rules and the model of grabbing the entrance of a bottleneck. In our simulation, as demonstrated by various examples, the asymmetry lane-changing and the heterogeneous distribution of vehicles easily result in complex fluctuations of traffic flow and jam.
