The invention relates to an arterial traffic four-intersection control sub-area bidirectional
green wave coordination control method based on phase
sequence optimization. A new cycle calculating formula is provided, the problem that a
signal cycle value obtained with an original cycle formula is small is solved, and a more reasonable
signal cycle is generated. A four-intersection phase sequence simultaneous-optimization method is designed, the phase sequence of intersections of four-intersection control sub-areas is optimized through a speed prediction control reward function, guide vehicle speeds corresponding to different road sections are given according to the optimized phase sequence, smooth bidirectional green
waves are formed by the control sub-areas, and phase segmentation and upper-lower-line phase conflicting are avoided. The arterial traffic four-intersection control sub-area bidirectional
green wave coordination control method has the advantages that the more reasonable
signal cycle is generated, the vehicle speed on an
artery can be highest within an allowed range under the manual control condition, the traveling time is saved, phase changes of the intersections are stable and smooth, the integrity of the phase sequence
green time is guaranteed, conflicting of an original
artery coordination
control mode to control over road physical conditions and phase segmentation are overcome, and the arterial traffic four-intersection control sub-area bidirectional
green wave coordination control method is an efficient and simple
artery coordination control method.
