Driver Source-Based Traffic Control Approach for Mitigating Congestion in Freeway Bottlenecks

Figure 1

Illustration of the driver sources of a bottleneck freeway segment. The red dots denote the on-ramps that contribute to the traffic flow of the bottleneck freeway segment, which are defined as the driver sources in this study. The on-ramps that do not contribute to the traffic flow of the bottleneck freeway segment are denoted by the grey nodes. The freeway segments that drivers use to travel from the driver sources to the bottleneck freeway segment are highlighted in blue.
