The invention relates to a traffic signal control field, discloses method and system of dynamic adjust signal time according to traffic flows in order to decrease stops/starts and green-light idle time: method includes: 1) get parameters of roadnet, signals; 2) get traffic flows; 3) I-neurons predict traffic flows about over thresholds; 4) P-neuron determine pre-judges according to over thresholds of intersection; 5) overall trade-off accept/reject, priority, schedule, and management of pre-judges, make and send I-instructions; system includes: 1) predict method package; 2) traffic data center or vehicle queue detecting equipments; 3) or vehicle in/out detectors; 4) traffic signals controllers. The predicting math model based signals net universal “A-A” serial method, support String mode control, enable roadnet traffic always run low energy consumption signals, avoid redundant stops/starts one time per period per vehicle per road-segment about 60 seconds and idle gasoline consumption, 30 vehicles about 30 minutes idle gasoline consumption per road-segment, and with solitary wave technique for dissolving jam-core, suddenly-happened big queue, provide a serial continuity solution means for signal control to dissolve congestion core, early congestion, delay arrival of a large cluster of congestion, improve efficiency of traffic signal response.
