Abstract-This paper deals with the robust local H∞ regulation of a freeway section. The model used to describe the onramp neighborhood is a discrete-time linear switching model. We extended this model with parametric uncertainties. We propose to design a bank of robust PI controllers to ensure that the system follows the concentration references even in presence of parametric uncertainties and exogenous disturbances. These controllers are computed using LMI resolution.

“…The onramp metering aims at the improving of traffic condition by controlling the inflow of freeways. Most of the solution proposed are based on a hierarchical architecture [14], [7], [9]. This architecture is constituted by the high level (⇔optimization layer) and by the low level (⇔local controller level).…”

Abstract-Following about 40 years of successful deployment of coordinated traffic-responsive ramp control, a new generation is being developed for Minnesota's freeways based on density measurements, rather than flow rates. This was motivated from recent research indicating that the critical value of density at which capacity is observed is less sensitive and more stable than capacity, thereby allowing the opportunity for more effective control. The main goals of the new approach are to delay the onset of the breakdown and accelerate system recovery when ramp metering is disabled due to the violation of maximum allowable ramp waiting times. This is obtained by a dynamic zone partitioning of the freeway network to identify critical bottleneck locations and coordinated balancing of ramp delays, which aims to avoid mainline breakdown. The effectiveness of the new control strategy is assessed by comparison with the currently deployed version of the stratified zone metering algorithm through microscopic simulation of a real 12-mi 17-ramp freeway section. Simulations show a decrease in delays of mainline and ramp traffic and an improvement of 8% in overall system delays while avoiding maximum ramp delay violations.
