This study assessed the ability of people with visual impairments to reliably detect oncoming traffic at crossing situations with no traffic control. In at least one condition, the participants could not hear vehicles to afford a safe crossing time when sound levels were as quiet as possible. Significant predictors of detection accounted for a third of the variation in the detection time.
本研究评估了视力障碍者在无交通管制的十字路口可靠检测迎面驶来车辆的能力。在至少一种情况下,当声音水平尽可能安静时,参与者听不到车辆声音,无法获得安全的过马路时间。检测的显著预测因素占检测时间变化的三分之一。
