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.

Claim (Index 1):
A method for a String SuperMode used in road traffic signal network includes steps:\n S1: Set RATIO as initial state with obtaining the length and traffic-times of every road-segment of a roadnet; S 2  calculate and configure new String Supermode according to a String Supermode instruction: 1) set the basic parameters: 1.1) divide the roadnet area of intersections into several subareas, 1.2) or redistribute period and speed limit according to the features of road-segments, 1.3) or equip signal devices for limit speed, countdown timer, change-speed including guideboard, vehicle navigator, mobile communication equipment or autopilot system, etc; 2) configure the 2D mode of greenwave in each said subarea of the String Supermode structure, said 2D mode of greenwave including IDEN-Lead mode, IDEN-Jam-Relief mode, DIFF mode, etc, the combination of the origins' positions and their master directions of 2D mode in said subareas determine the class of String SuperModes, vice-verse , 2.1) determine the position of the origin of instructed 2D mode of every subarea: an intersection at a corner in a subarea, {circle around (1)} determine master/slave directions, {circle around (2)} determine Lead/Jam-Relief greenwave, {circle around (3)} get the position of an origin and the configuring channels of 2D greenwave time-offsets and their strat-intersections: for 2D Lead mode of greenwaves, i.e. IDEN-Lead mode, its origin is the intersection of the most upstream intersection both of master direction and of slave one, the start-intersection from where every master direction channel's every intersection's greenwave time-offset is calculated is its channel most upstream intersection, the configuring channel of slave greenwave time-offsets is composed of the start-intersections of master direction channels and its start-intersection is the above origin; for 2D Jam-Relief mode of greenwaves, i.e. IDEN-Jam-Relief mode, its origin is the intersection of the most downstream intersection both of master direction and of slave one, the start-intersection from where every master direction channel's every intersection's greenwave time-offset is calculated is its channel most downstream intersection, the configuring channel of slave greenwave time-offsets is composed of the start-intersections of master direction channels and its start-intersection is the above origin; for 2D Lead and Jam-Relief mode of greenwaves, i.e. DIFF-mix mode, its origin is the intersection both of the most upstream intersection of Led direction and of the most downstream intersection of Jam-Relieved direction, the start-intersection from where every led direction channel's every intersection's master greenwave time-offset is calculated is its channel most upstream intersection, the configuring channel of slave greenwave time-offsets is composed of the start-intersections of master direction channels and its start-intersection is the above origin, and for 2D Jam-Relief and Lead mode, i.e., the master-Lead direction and slave-Jam-Relief exchange of DIFF-mix mode: and also the master-Jam-Relief direction and slave-Lead direction; 2.2)calculate the greenwave time-offsets of every intersection and configure its interim period: {circle around (1)} determine the traffic-time of the time-offsets of every road-segment, Lead mode uses set-drive-times to sum, Lead mode uses JVQ-start-times to sum, {circle around (2)} calculate the time-offset t 1  from its start-intersection of every intersection of a master channel, {circle around (3)} calculate the time-offset t 2  from the origin intersection of every intersection of the slave time-offset configuring channel, {circle around (4)} add master time-offset t 1  and slave tie-offset t 2 , get 2D mode time-offset t , {circle around (5)} obtain the period remainder of the 2D mode time-offset t, {circle around (6)} make the period remainder a signal interim period of every intersection: the remainder as time=North-South permit time+East-West permit time; S 3  run RATIO mode after running out the respective interim period of every intersection with red-light-on or without signals.
