行人在环形交叉路口的行为和安全还没有得到很好的理解，特别是对于有感官或行动障碍的行人。之前的一项研究表明，参与者表示他们何时会过马路，这表明盲人行人比有视力的行人错过了更多的过马路机会，做出了更危险的判断。本研究复制了这些发现，并分析了实际的街道交叉口。六个盲人和六个有视力的行人在高低交通量下通过一个双车道的城市环形交叉路口。失明的参与者等待穿越的时间是视力正常的参与者的三倍。大约6%的盲人参与者的过马路尝试被认为是危险的，需要干预，而有视力的行人则没有。司机经常在入口车道上让步，但在出口车道上却没有。有视力的参与者接受司机的让步，而盲人参与者很少这样做。盲人视力的差异解释在听觉上获得有关交通的信息，并讨论了交通系统的可访问性的政策含义。
Pedestrian behavior and safety at roundabouts are not well understood, particularly for pedestrians with sensory or mobility impairments. A previous study in which participants indicated when they would cross suggested that blind pedestrians miss more crossing opportunities and make riskier judgments than sighted pedestrians. The present study replicated these findings and analyzed actual street crossings. Six blind and six sighted pedestrians negotiated a double-lane urban roundabout under high and low traffic volumes. Blind participants waited three times longer to cross than sighted participants. About 6% of the blind participants' crossing attempts were judged dangerous enough to require intervention, compared to none for sighted pedestrians. Drivers yielded frequently on the entry lanes but not the exit lanes. Sighted participants accepted drivers' yields, whereas blind participants rarely did so. Blind-sighted differences are interpreted in terms of auditory access to information about traffic, and policy implications are discussed regarding accessibility of transportation systems.
