Abstract:
The main objective of this paper is to illustrate the applicability
and potential advantages of model-based traffic control for the
reduction of emissions. We investigate the impact of a model-based
control strategy on emissions and traffic flow using model predictive
control (MPC). We consider reduction of emissions and total time spent
(TTS). The MPC controller is based on a car-following traffic flow
model and an average-speed-based emission model. Moreover, we
illustrate that a control strategy, that only addresses the
improvement of traffic flow does not necessarily guarantee improvement
in the level of emissions. We demonstrate that a traffic control
strategy (such as MPC) addressing emissions and total time spent can
result in a balanced reduction of emissions and total time spent.
Using simulation, we analyse the effects of different weighting
combinations on the different emission gases of traffic flow and the
TTS. We illustrate with a simulation example that the proposed traffic
control approach can reduce both emissions and TTS. Simulation results
show 11.1% reduction in average time spent, and 37.55% reduction in
total average emission levels.
