Using the spatial and temporal characteristics of vehicle movement to analyze the control effect of the corridor progression, we can deeply explore the essential principle of progression design. Based on the progression design principle and the geometric elements' transformation in the time-space diagram, a graphical optimization method for bidirectional corridor progression under the split phasing design is proposed. The initial comprehensive optimization determines the initial coordinated design scheme, and the iterative optimization re-optimizes the signal phase sequence, signal cycle, and offset. The case study shows that the proposed graphical method can quickly obtain a coordinated control scheme for the corridor with significant bandwidths in both directions. Simulation analysis using VISSIM shows that the proposed graphical method brings an optimal progression effect better than the PBAND method. The proposed method has a straightforward design process, a continuous optimization space, and a fast solution speed, which leads to its certain engineering application value.
