Impact of Inside Intersection Pavement Markings to Mobility Performance at Urban Signalized Intersections in Japan and the Philippines

Inside intersection pavement markings category in Japan and Philippines are different, and the difference of its impact to mobility performance are still unknown. Left-turn lanes (right-turn in Japan) is one of key movements in urban signalized intersections and their capacity must be maximized. This paper aims to investigate the difference of the mobility performance of the right-turn guide lines in Japan and Yellow-Box pavement markings in the Philippines in terms of saturation flow rate, trajectory variation and speed. The analysis reveals that the turn guide lines are effective in achieving small turning vehicle trajectory variation and high saturation flow rate which are affected by the traffic signal phasing and the geometric layout of the turn lanes of the signalized intersection. The absence of guide lines of yellow box pavement markings creates cross-maneuvering behavior that lower the saturation flow rate of the turning lane.
