Abstract
The invention relates to a traffic signal mode field, discloses method enabling traffic signal running greenwave in the two cross direction within the whole roadnet, the control method comprises the following steps: calculating the allocation ratio mode with obtaining the set-driving-time of road-segments; calculation of the 2-D greenwave-offset on the corner-intersection of the roadnet; run RATIO mode after the 2-D greenwave-offset run out. The invention can make the same directional flow (isotropic) with the characteristics of the medium flow traffic load reduce waiting-time for more than 15% compared with the 1-D greenwave signal mode to, reduce greater than 30% compared with the ratio of signal to, and reduce more waiting-time further if adjusting signal-mode to matching traffic flow characteristics, and greatly improve the efficiency of transportation.
