Traffic congestion control using group metering

Abstract

The interest in maximizing the road utility has been increased. For maximizing the road utility, the vehicle density in the road should be optimized, otherwise there would be traffic congestion. To remove the congestion, the entrance of vehicle to the road should be controlled. On-ramp metering control strategy using group metering is proposed in this dissertation. Group metering reduces the number of metering gates but introduces the parameters with structured uncertainty, which needs more elaborate control algorithm. In this dissertation, robust and adaptive control strategy is proposed for single and multi-congestion case. With robust control, the control parameter to stabilize the network system in any traffic pattern is determined. And with adaptive control, the desired transient response for current traffic pattern is available by locating the poles in the specific bound. Finally, a control strategy for multi-congestion case is proposed.
