Abstract
After heated discussion, National Police Agency decided not to install Red Arrow signal at such major intersections as Gwanghwamoon, Sejongro. The major issues can be summarized in the following reasons. The one is the conflict of color and symbol (red means STOP and arrow means PROGRESS), and it would confuse drivers and may cause traffic accident. The other includes high replacement cost. This paper delivered how much red arrow signal would affect (1) drivers start up delay time, (2) saturation flow rate and (3) vehicle headway. The result showed that there was no statistical difference in those even when a red arrow signal is placed.
