T his method can be used to optimize the phase sequence of each intersection, determine the optimal common signal cycle and signal offsets, and calculate the green w ave bandw idth in different arterial road directions. Analysis results show that compared w ith the algebraic method in the signal design mode of one- phase-symmetry-flow , this method can be used to select the ideal intersection spacing
