It is a common practice for left turning vehicles (left hand traffic system) to share the same traffic signal phase with pedestrian at signalized intersection. Although signalized crosswalk are operated to give pedestrians prioritized right of way, accident data reveal that left turning vehicles are not always being able to give pedestrians their right of way. As such, it is important to find the reasons for why the left turning vehicle driver fails to grant a legally-crossing the pedestrian right of way. To investigate the effect of intersection angle on the yielding behavior of the left turning vehicle driver with pedestrians, this study used data from an observational study, conducted at nine signalized intersections in Japan in 2013. In this study events related with sudden brake and acceleration for avoiding collision is considered as “non-yielding” behavior. The results show that driver's behavior at obtuse angled intersections is more "non-yielding" than other typed intersections.
