Figure 7

(a), (b) Optimization of traffic flow for freeway bottlenecks of Beijing-Hong Kong-Macao Expressway and Changzhou-Zhangjiajie Expressway. The bar chart indicates the reduction in traffic flow after implementing the traffic control scheme. The dashed black line represents the target traffic flow volume , whereas the blue solid line represents the traffic flow under traffic control.
