Ramp metering: modeling, simulations and control issues

  title={Ramp metering: modeling, simulations and control issues},
  author={C{\'e}dric Join and Hassane Aboua{\"i}ssa and Michel Fliess},
The aim of ramp metering is to improve the highway traffic conditions by an appropriate regulation of the inflow from the on-ramps to the highway mainstream. Our presentation rests on several improvements: 1) Our simulation techniques do not need contrarily to other approaches any heuristic fundamental law. 2) There is no need of crucial time-varying quantities, like the critical density, which is most difficult to estimate correctly online. 3) Our feedback loop, which is stemming from model… 

Active queue management: First steps toward a new control-theoretic viewpoint

Active Queue Management for mitigating Internet congestion has been addressed via various feedback control syntheses, among which P, PI, and PID regulators are quite popular and often associated to a Smith predictor, but to better account for the many uncertainties, the above controllers are replaced by an intelligent proportional controller associated to Model-Free Control.

Model-Free Control Policies for Inventory Management in Supply Chain

In the frame of supply chain networks, several approaches stemming from control theory seem to be more adapted to deal with dynamic inventory management. Nevertheless, the used methods, until today,

This paper exploits the recent advances on model-free control and proposes a robust and easy implement able algorithm to deal with the DTR problem in the case of non-recurrent congestions.

Toward more realistic social distancing policies via advanced feedback control

A feedback control where the transmission rate, i.e., the control variable, is piecewise constant and remains constant during an appreciable time interval so that strict extended lockdowns may be avoided.

An Efficient Framework for Tactical Management in Supply Chain Systems

Although dynamic supply chain management is nowadays quite widely studied, several problems related to their control remain a challenging task. Indeed, most of the methods are model-based control

A fresh look at ramp metering control: ALINEA without any tedious calibration

This report shows that ALINEA may be slightly modified in order to be efficiently implemented without any need of crucial time-varying quantities, like the critical density and the free-flow speed, which are most difficult to estimate correctly online.

On ramp metering: towards a better understanding of ALINEA via model-free control

A theoretical proof of its efficiency at least when the traffic conditions are rather mild is given here, perhaps the first time, and relies on tools stemming from the new model-free control and the corresponding ‘intelligent’ proportional controllers.


ALINEA, a new local traffic-responsive strategy for ramp metering, is presented. The new control strategy is based on a feedback structure and is derived by use of classical automatic control

Feedback Ramp Metering in Intelligent Transportation Systems

This book provides traffic theory fundamentals and then the design of feedback controllers for isolated and coordinated ramp metering problems, and software simulation code in Matlab and Paramics is provided so that the reader can get a hands-on feel for the various algorithms.

Freeway ramp metering control made easy and efficient

"Model-free" control and the related "intelligent" proportional-integral (PI) controllers are successfully applied to freeway ramp metering control thanks to new estimation techniques where the differentiation of noisy signals plays a key role.

Heuristic Ramp-Metering Coordination Strategy Implemented at Monash Freeway, Australia

A new traffic-responsive feedback control strategy, heuristic ramp-metering coordination (HERO) that coordinates local ramp- Metering actions in freeway networks is presented, which outperforms uncoordinated local ramp metering and approaches the efficiency of sophisticated optimal control schemes.

Traffic flow modeling of large-scale motorwaynetworks using the macroscopic modeling tool METANET

The macroscopic simulator METANET, involving a second-order traffic flow model as well as network-relevant extensions, is utilized and a rigorous quantitative validation procedure is applied to individual network links, and subsequently a heuristic qualitative validate procedure is employed at a network level.
