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 6):
A method as defined in  claim 1 , wherein the 2) of step S2 includes the steps of:\n S21 when an interim category is wave-initial, configure wi-interim-period: calculate and configure the greenwave time-offset of every intersection and its interim-period: (S21.1) according to the running rules of the two modes determine the positions of their source-intersections, for a raw RATIO, the source-intersection can be any intersection in a roadnet due to the synchronization of all the intersections, for a greenwave mode, the source-intersection can be determined by the greenwave mode, the source-intersection of a Lead greenwave mode is the first intersection in its channel led traffic direction, the source-intersection of a Jam-Relief greenwave mode is the last intersection in its relieved channel traffic direction, a Lead greenwave direction is same as its channel led traffic direction, but a Jam-Relief greenwave direction is reverse of its channel relieved traffic direction; the 2D modes includes IDEN-Lead, IDEN-Jam-Relief, DIFF-Mix, their origin source-intersections all are at a corner in an area, called as corner-intersection, for a IDEN-Lead mode, the origin intersection is the first intersection both of a direction Lead greenwave and of its cross direction Lead greenwave, for a IDEN-Jam-Relief mode, the origin intersection is the last intersection both of a direction Jam-Relief greenwave and of its cross direction Jam-Relief greenwave, for a DIFF-Mix mode, the origin intersection is the first intersection of a direction led traffic channel with Lead greenwave but the last intersection of its cross direction relieved traffic channel with Jam-Relief greenwave, set one of the two directions as master direction and the other as slave, the source-intersection of the greenwave time-offsets of slave direction channel is the corner-intersection which is one of the source-intersections of master direction greenwave channels; (S21.2) according to the running rules of the two modes determine their time-offsets of every intersection: the sum of the traffic-time from the corner-intersection to one of its downstream intersections for each mode, then get their respective remainder by dividing the sum by the period; (S21.3) configure the wi-interim-period: make a signal interim-period with the remainder, i.e., wi-interim-period;
