TRAFFIC NOISE AND TRAFFIC LIGHT CONTROL

摘要

An optimal control problem of traffic light duration isconsidered. The traffic noise level is intro- duced as a statevariable in a dynamical optimization problem. A closed loop controlsystem is designed which influences the green duration of the lightsaccording to the equivalent noise level. Real time con- siderationslead to sub-optimal control implementation. This control policydecreases the noise levels at intensive traffic intersections. Thetraffic lights adapt their duration according tot he noise pollution.Simu- lation and experimental results are discussed.
