Algebraic Method of Arterial Progression Based on Green Center Line

Abstract

An algebraic method of arterial progression based on the green center line was presented in this study, which optimized the common signal cycle, phase sequence of each intersection, and offsets by seeking the ideal intersection positions with a small bias distance from the actual intersection positions. Since the bias split would determine the progression bandwidth and impact the progression effect directly, this method took the maximum difference of all bias splits as an evaluation index for scheme optimization. This method was applied to obtain an arterial progression for the 21 signalized intersections on Huanshi West Road in Nansha District, Guangzhou. Compared with the MAXBAND, MULTIBAND model, and the Synchro software, the VISSIM simulation results showed that the algebraic method achieved the best coordinated control effect for the through vehicles along the artery. The schemes obtained by the MULTIBAND model and algebraic method achieved the minimum delay and number of stops for all through vehicles on each road section.
