Abstract
This paper proposes a new ramp metering control algorithm, Feed-Forward ALINEA
(FF-ALINEA), for bottlenecks located both nearby on an on-ramp and further away
from it (i.e. more than just a few hundred meters). The formulation of the
controller is based on a feed-forward modification of the well-known control
algorithm for ramp metering, ALINEA. The feed-forward structure allows to
anticipate the future evolution of the bottleneck density in order to avoid or
reduce traffic breakdowns. The proposed controller is tested, using the
macroscopic traffic flow model METANET, for 9 scenarios and the results are
compared with the ones obtained with ALINEA, PI-ALINEA, and with the optimal
solution. The simulations show that FF-ALINEA is able to approach the optimal
behavior, thereby outperforming ALINEA and PI-ALINEA. Moreover, results
indicate that FF-ALINEA is quite robust in cases where different demands are
considered, there is a limited number of available detectors, or there are
errors in the estimation of the capacity and/or the critical density of the
bottleneck.
