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 …

The emerging technologies of connectivity and automation enable the potential for signal-
free intersection control. In this context, virtual platooning is posited to be an innovative …

When freeway traffic is dense, shock waves may appear. These shock waves result in longer
travel times and in sudden large variations in the speeds of the vehicles, which could lead to …

The emergence of automated vehicles may have significant impacts on traffic flow. While
many studies suggest that fully automated vehicles can improve traffic flow by changing their …

A nonlinear model-predictive hierarchical control approach is presented for coordinated
ramp metering of freeway networks. The utilized hierarchical structure consists of three …

A new traffic-responsive feedback control strategy, heuristic ramp-metering coordination
(HERO) that coordinates local ramp-metering actions in freeway networks is presented. The …

In this section we give a characterization of freeway traffic problems and briefly discuss the
motivation for the traffic control problem statement in Section 1.2. A full policy analysis is out …

Some of the criticalities associated with traffic phenomena in freeway networks can be
mitigated or even eliminated with suitable control strategies. The most important and evident …

This article presents a study on freeway networks instrumented with coordinated ramp
metering and the ability of such control systems to produce arbitrarily complex congestion …

The objective of this paper is the regulation of freeway traffic by means of optimal control
techniques. A first innovative aspect of the proposed approach is the adopted objective …
