Abstract:
The invention relates to a traffic signal mode field, discloses a method that supports the mode-changing of traffic signals in real time, acts including: 1) recognize a mode instruction, 2) calculate and configure the interim period according to the mode instruction, 3) run the instructed mode after the interim period runs out. The present invention optimizes signal mode conversion, shorten the time of signal mode conversion, obtain 0 redundent waiting mode conversion and smoothly switching, lessen the response time of signals with traffic change, solving the beset “A mode response for smooth traffic may turn out to be an aggravating congestion factor.”, improving the real time performance of traffic signal system. Even if the remainder as wait is compared with for mode switching, this invention also improves the signal efficiency 50%, lessens redundant wait by 50%, makes the smooth conversion of signal modes, avoids traffic jam due to mode changing execellently.

Claim (Index 1):
A method for real time changing mode used in road traffic signal network includes steps:\n S1: Set RATIO as initial state with obtaining the length and its traffic-time of every road-segment of a roadnet; S2 set new mode and its interim time-offsets based on a new mode instruction: 1) determine the interim category according to a mode-instruction and the current running mode: wave-initial, wave-delete, or wave-wave, said wave-initial is a mode instruction that orders an intersection to change from a RATIO mode to a greenwave mode, said wave-delete is a mode instruction that orders an intersection to change from current greenwave mode back to RATIO mode, said wave-wave is a mode instruction that orders an intersection to change from current greenwave mode to another greenwave mode; 2) calculate interim-period according to the category: (2.1) find the source-intersections and their positons of the two modes; (2.2) calculate the time-offsets and their period remainder of the new mode of every intersection: said period remainder=remainder of the time-offset/period; (2.3) configure the interim-period corresponding to the period remainder: interim-period=period remainder=master direction interim+slave direction interim; S3 run the new mode after running out the interim-period of every intersection with red-light-on or without signals;
