A Convex Reformulation of the Robust Freeway Network Control Problem with Controlled Merging Junctions
Marius Schmitt, John Lygeros
In the freeway network control (FNC) problem, the operation of a traffic network is optimized using only flow control. For special cases of the FNC problem, in particular the case…
On monotonicity of FIFO-diverging junctions
Marius Schmitt, John Lygeros
This technical note concerns the dynamics of FIFO-diverging junctions in compartmental models for traffic networks. Many strong results on the dynamical behavior of such traffic ne…
An Exact Convex Relaxation of the Freeway Network Control Problem with Controlled Merging Junctions
Marius Schmitt, John Lygeros
We consider the freeway network control problem where the aim is to optimize the operation of traffic networks modeled by the Cell Transmission Model via ramp metering and partial…
An Integrated and Scalable Platform for Proactive Event-Driven Traffic Management
Alain Kibangou, Alexander Artikis, Evangelos Michelioudakis +7
Traffic on freeways can be managed by means of ramp meters from Road Traffic Control rooms. Human operators cannot efficiently manage a network of ramp meters. To support them, we…
Sufficient Optimality Conditions for Distributed, Non-Predictive Ramp Metering in the Monotonic Cell Transmission Model
Marius Schmitt, Chithrupa Ramesh, John Lygeros
We consider the ramp metering problem for a freeway stretch modeled by the Cell Transmission Model. Assuming perfect model knowledge and perfect traffic demand prediction, the ramp…
Distributed Learning in the Presence of Disturbances
Chithrupa Ramesh, Marius Schmitt, John Lygeros
We consider a problem where multiple agents must learn an action profile that maximises the sum of their utilities in a distributed manner. The agents are assumed to have no knowle…
