Abstract

The invention relates to a traffic signal mode field, discloses a method for a supermode of traffic signal control: String Supermode, its main steps includes: 1)get String Supermode instruction; 2)set the basic parameters of String Supermode: subareas of a roadnet, period-redistribution; 3)set 2D greenwave mode in the relative subareas according to a String Supermode structure; 4)calculate the 2D greenwave time-offsets and their interim-period in each subarea; 5)run new mode after the above interim-period run out. The present invention realizes the effectiveness of signals equilibrium, high effieciency, multi-purpose, universe, easy to use: vehicles entering Wormhole-area from any direction and going to any position of the diagonal far-corner area, need 4.5 times of red lights on average, no matter how large a Wormhole-class controlled area and how big the number of intersections in the area are, multiple-class-change based on Wormhole-class presents the functions of the fast inhalation of vehicle flow from omni-direction, :the fast spitting out of vehicle flow to omni-direction, the relieving jammed vehicle flow during spitting out to omni-direction, the relieving jammed vehicle flow during inhalation from omni-direction, the coordinating artery roads to quickly shunting vehicle flow, and also, the vehicles' going through an area by only 1 red light of Pulsar-class; this String Supermodes are determined by only about 20 of parameters, can switch rapidly with no redundance, provide an area-type traffic control, analysis, operation basic mode.
