. . . . Influencing Driver Yielding Behavior Gene Bourquin, Rob Wall, Dona Sauerburger at crossings without traffic controls
. . . . Influencing Driver Yielding Behavior What conditions cause drivers to yield: vests, flags, and cane, oh my?
. . . . Influencing Driver Yielding Behavior Why drivers yield?
. . . . Influencing Driver Yielding Behavior Social theories and empirical research indicate that dependency cues influence drivers Harrell (1993)
. . . . Influencing Driver Yielding Behavior (Bake & Reitz, 1978) Drivers yielded more readily to individuals perceived to be dependent: mothers with a carriage, people thought to have a physical disability, or people who are blind.
. . . . Influencing Driver Yielding Behavior What drivers see
. . . . Influencing Driver Yielding Behavior (Hughes, Vachon, & Jones, 2005) Attentional capture: a stimulus that alters attention away from the prevailing focus…which draw a attention without that person’s volition.
. . . . Influencing Driver Yielding Behavior What’s in your attention set? (Mack, Pappas, Silverman, & Gay, 2002)
. . . . Influencing Driver Yielding Behavior (Ramachandran & Rogers-Ramachandran, 2005) Inattentional Blindness: the phenomenon when items not expected, not of interest, or not meaningful are not perceived by the visual system.
. . . . Influencing Driver Yielding Behavior Conditions are likely to be noticed and understood when attentional capture is high and inattentional blindness in minimized.
. . . . Influencing Driver Yielding Behavior What we knew about drivers’ yielding
. . . . Influencing Driver Yielding Behavior driver yielding for pedestrians approaching crosswalk at a roundabout: no white cane: 52% drivers with white cane: 63% drivers (Geruschat and Hassan, 2005)
. . . . Influencing Driver Yielding Behavior driver yielding for pedestrians standing at roundabout crosswalks with a visible long white cane or dog (Ashmead, Guth, Wall, Long, & Ponchillia, 2005)
. . . . Influencing Driver Yielding Behavior Entry lanes (slower): No cane / dog: 20% With cane / dog: 36.4% Exit lanes (faster): No cane / dog: 0% With cane / dog: 9% (Ashmead, Guth, Wall, Long, & Ponchillia, 2005)
. . . . Influencing Driver Yielding Behavior driver yielding for pedestrians standing at crosswalk with a visible long white cane or dog (Guth, Ashmead, Long, Wall, & Ponchillia, 2005)
. . . . Influencing Driver Yielding Behavior mid-block campus crossing: no cane/dog: 80% trials with cane/dog: 96% trial (Guth, Ashmead, Long, Wall, & Ponchillia, 2005)
. . . . Influencing Driver Yielding Behavior Uncontrolled crossing at downtown intersection (stop sign on intersecting street): no cane/dog: 5% trials with cane/dog: 7% trials (Guth, Ashmead, Long, Wall, & Ponchillia, 2005)
. . . . Influencing Driver Yielding Behavior What we did What we found
C2 P C1 . . . . Influencing Driver Yielding Behavior X
. . . . Influencing Driver Yielding Behavior 375 trials
. . . . Influencing Driver Yielding Behavior Control yielding rate: 0.41 Flag 0.62 Vest 0.49 Cane 0.87 Cane waive 0.89 Cane waive vest 0.91
. . . . Influencing Driver Yielding Behavior The main differences seen in yielding were across the crossing conditions
. . . . Influencing Driver Yielding Behavior Secondarily, vehicle approach speed most critically impacted yielding
. . . . Influencing Driver Yielding Behavior This study, along with previous studies, indicate a general principle that using a cane will improve safety. A long cane is a well-known symbol that reduces inattention blindness through its visibility and meaningfulness.
