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

Table 3

Results for controlling traffic flow from the major driver sources of the freeway bottleneck versus controlling the traffic flow from the upstream on-ramps near the freeway bottleneck.

Traffic control approach	Decrease in maximum vehicle flow (%)	Optimization performance (%)
Controlling the major vehicle source of the freeway bottleneck	14.41	7.19
Controlling the on-ramps near the freeway bottleneck	8.47	5.15
