摘要
An optimal control problem of traffic light duration is considered. The traffic noise level is introduced as a state variable ina dynamical optimization problem. A closed loop control system is designed which influences the green duration of the lights according to the equivalent noise level. Real time considerations lead to sub-optimal control implementation. This control policy decreases the noise levels at intensive traffic intersections. The traffic lights adapt their duration according to the noise pollution. Simulation and experimental results are discussed. (C) 1998 Elsevier Science Ltd. All rights reserved.
