Popis: Objective The objective was to explore the effect of driver Situational Awareness (SA) on “right-hook” bicycle-motor vehicle crashes involving right turns into adjacent bicyclists. Background Previous literature suggests that improper allocation of motorists’ visual attention, inadequate surveillance, and poor SA are contributing factors to bicycle-motor vehicle crashes in other types of encounters. Method Fifty-one participants completed this driving simulator study. Right-turning motorists’ SA was measured using the SAGAT technique in the presence of a through-moving bicyclist in an adjacent bicycle lane during the latter portion of the green phase at a signalized intersection using a three (bicyclist’s relative position) by two (presence of oncoming left-turning vehicle) within-subject factorial design. Each participant made 21 right turns, nine of which were immediately followed by SA queries, and crash avoidance behavior was measured at the last intersection, which involved a crash-likely scenario. Results The bicyclist’s position significantly influenced motorists’ overall SA (p Conclusion Motorists focused more attention on cars in front of them and less attention on bicycles in the peripheral vision. A common cause of observed crashes in the simulator was detection error. The bicyclist approaching from behind the motorist is the most vulnerable to a right-turning motorist.
