A Study on Signal Offset Settings during Oversaturation

Abstract

The purpose of this study is to investigate signal offset settings during oversaturation. The study considered a wide variety of factors that might influence the number of discharged vehicles, including the distance between intersections, a cycle length and green duration. I investigated offset settings by analyzing time-space trajectories of vehicles. As a result, I identified the relation among offset, the number of discharged vehicles and these factors, and showed the procedure for setting signal offset during oversaturation.
