Isolated Ramp Metering Feedback Control Utilizing Mixed Sensitivity for Desired Mainline Density and Ramp Queues

This paper presents a feedback control design for isolated ramp metering control. This feedback control design, unlike the existing isolated feedback ramp controllers, also takes into account the ramp queue length. Using a nonlinear H(infinity) control design methodology, we formulate the problem in the desired setting to be able to utilize the results of the methodology

A new ramp metering control algorithm for optimizing freeway travel times

"In many cities around the world traffic congestion has been increasing faster than can be dealt with by new road construction. To resolve this problem traffic management devices and technology such as ramp meters are increasingly being utilized."--leaf 1.Masters of Information Technolog
