Faculty Civil Engineering and Geosciences Department Transport and Planning Date 2014-01-12 Abstract We present a new control strategy that aims to reduce total delay at sags. The strategy is based on the concept of mainstream traffic flow control. The traffic density at the bottleneck area is regulated in order to keep it slightly below the critical density, hence preventing traffic from breaking down while maximizing outflow. Density is regulated by means of a variable speed limit section that regulates the inflow to the bottleneck. Speed limits are set based on a proportional feedback control law. We evaluate the effectiveness of the control strategy by means of a case study using microscopic traffic simulation. The results show a significant increase in bottleneck outflow, particularly during periods of high demand, which considerably reduces delay.
