Abstract:
The equations describing the relationship of phase difference adjustment quantities were established for intersection before and after transition. Considering the allowable range of each intersection's signal cycle length in transition period, the single-cycle symmetrical adjustment transition algorithm and the N-cycle weighted adjustment transition algorithm were proposed based on the minimax principle of offset adjustment ratio. Analysis result shows that when the symmetrical adjustment transition algorithm is finished in one cycle, and the actual maximum adjustment of intersection phase difference is minimized. The weighted adjustment transition algorithm comprehensively consideres the allowable range of each intersection's transition signal cycle, and can make a coordinated control scheme rapidly and smoothly transit to a new coordinated control scheme after N transition signal cycles based on the minimum requirement of the maximum adjustment ratio of phase difference. Compared with other transition algorithms, the global optimization of phase difference adjustment for all intersections in control area can be realized by the weighted adjustment transition algorithm, which better satisfy the control demands of different signal intersections, so the weighted adjustment transition algorithm is more practical and has a broader application scope. 2 tabs, 7 figs, 16 refs.
