Abstract

The invention concerns traffic signal control, is optimized period and green time ratio green wave control method, main steps includes: 1) build polarized period spectrum; 2) decide polarized period spectrum tactics; 3) AI optimized polarized period spectrum; 4) configure polarized green-wave interim and period; 5) run polarized green-wave, including differential green-wave and optimization time interval; Advantage: both provides concrete signal scheme/control methods of broad band traffic signal period/green time ratio to road-net that spreads very heavy traffic at some intersections of non-uniform traffic loads, and an interface frame for obtaining and dealing with traffic data/optimizing signals' parameters using AI tech dynamically on line; comparing to current traffic signal systems, waiting time is lessened by far more than 30%, efficiency of transportation is improved greatly; whose attributes as universal model easy to embed new signal technology such as Pan String, String Super-mode, Lined Mixture, Pan-Green-Wave, differential green-wave, and whose frame features embedding AI's methods may realize wider gain of double broadband, including special signals for bus, application prospect is broad.
