The invention provides a varying-period signal coordinating and controlling method of road intersections. The method solves the problems that main road intersection signal coordinating and controlling methods in the prior art cannot flexibly conduct optimization or adjustment of the period, scheme and phase difference of traffic signal control in real time according to traffic flow changes. The method effectively improves the green light utilization rate and passing capability of road intersections, reduces the frequency of vehicle stopping, ensures main road green wave coordination and control effect, achieves quick transition of signal coordinating and controlling schemes at the same time, and eliminates influence to traffic caused during the scheme transition. The method monitors traffic flow data of each intersection in real time, calculates the optimal coordinating and controlling common period in real time, optimizes and adjusts city main road traffic signal coordinating and controlling schemes, selects the optimal phase difference, enables the main road traffic signal coordinating and controlling schemes to adapt to road traffic flow changes quickly, and thus improves the effect of main road traffic signal coordinating and controlling.
