Abstract:
In addition to the challenge to reduce traffic jams, reduction of
traffic emissions in such a way that the dispersion of the emissions
to residential areas, hospitals, schools, and other neighborhoods is
decreased is a problem that requires state-of-the-art traffic control
and management solutions. In this paper we model the dispersion of the
emissions from a freeway traffic using a grid-based approach where the
variability of the speed and direction wind is considered into
account. The model is developed in such a way that the computation
time is less than a previously proposed point-source model, while
still capturing the important dispersion dynamics so that it can be
used for on-line control applications. In order to reduce the
dispersion of emissions to a neighborhood we design a parametrized
model predictive control (MPC) strategy to optimize variable speed
limits and ramp metering rates. We illustrate the proposed dispersion
model and control approach with a simulation-based case study.
