Analysis on Safety Check Behaviors and Vehicle Movements at Roundabouts in Japan

DOI

Description

This study carried out driving experiments on safety check behaviors and vehicle movements at five roundabouts in Japan. Specifically, each driver's attention when entering or exiting the intersection was analyzed by using video and drive recorder data. As a result, it is revealed that the safety check position is positively correlated with the safety check speed for the case of entering roundabout, however this relationship is not clearly confirmed for the case of exiting roundabout, especially 4-leg roundabout cases. From the analyses of necessary deceleration rate (NDR) for safety stop before the crosswalk, it is found that colored pavement triggers high deceleration at roundabout entries. On the other hand, as for roundabout exits, it is revealed that 4-leg intersection has a high impact on the deceleration value, whereas both left turn movement and the existence of pedestrian at far side edge of crosswalk reduce the NDR value.
