Novel Freeway Traffic Control with Variable Speed Limit and Coordinated Ramp Metering
control freeway traffic in the United States, particularly in California. It is recognized that ramp metering can directly control the flow into the freeway (demand) and the average density immediately downstream, which indirectly affects the traffic upstream. After drivers enter the freeway, their collective behaviors are not controlled, which determines the traffic flow pattern. In addition, ...

This paper prcseirts aj'2edback contrd design for isolated ramp metering cmtrol. This feedback control design, i:nlike the existing isolated feedback ramp controllers, Glso ta1:es into account (he ramp queue length. Using a !ionlizmr Hm ;ontrol design methodology, we formulate ihe problem in the desired setting to be able to utilize the results of the methodolop.
متن کاملModel predictive control for optimal coordination of ramp metering and variable speed control
We apply model predictive control to optimally coordinate variable speed limits and ramp metering. The basic idea is that speed limits can increase the (density) range in which ramp metering is useful. For the prediction we use a slightly adapted version of the METANET traffic flow model that takes the variable speed limits into account. The optimal control signals aim at minimizing the total t...
متن کاملOptimal coordination of ramp metering and variable speed control – An MPC approach
We present a model predictive control (MPC) approach to optimally coordinate variable speed limits and ramp metering for highway traffic. The basic idea is that speed limits can increase the range in which ramp metering is useful. The control objective is to minimize the total time that vehicles spend in the network. For the prediction of the evolution of the traffic flows in the network we use...
متن کاملModel predictive control for optimal coordination of ramp metering and variable speed limits
This paper discusses the optimal coordination of variable speed limits and ramp metering in a freeway traffic network, where the objective of the control is to minimize the total time that vehicles spend in the network. Coordinated freeway traffic control is a new development where the control problem is to find the combination of control measures that results in the best network performance. T...
