The increasing number of hybrid and quiet internal combustion engine vehicles may impact the travel abilities of pedestrians who are blind. Pedestrians who rely on auditory cues for structuring their travel may face challenges in making crossing decisions in the presence of quiet vehicles. This article describes results of initial studies looking at the crossing decisions of pedestrians who are blind at an uncontrolled crossing (no traffic control) and a light controlled intersection. The presence of hybrid vehicles was a factor in each situation. At the uncontrolled crossing, Toyota hybrids were most difficult to detect but crossing decisions were made more often in small gaps ended by a Honda hybrid. These effects were seen only at speed under 20 mph. At the light controlled intersection, parallel surges of traffic were most difficult to detect when made up only of a Ford Escape hybrid. Results suggest that more controlled studies of vehicle characteristics impacting crossing decisions of pedestrians who are blind are warranted.
混合动力和安静的内燃机车辆数量不断增加，可能会影响盲人行人的出行能力。依靠听觉线索来规划行程的行人，在遇到安静的车辆时，做出过马路的决定可能会面临挑战。本文描述了初步研究的结果，该研究观察了盲人行人在无交通控制的交叉路口和有信号灯控制的十字路口的过马路决定。在每种情况下，混合动力车辆的存在都是一个因素。在无交通控制的交叉路口，丰田混合动力车最难被察觉，但在由本田混合动力车结束的小间隙中，行人更常做出过马路的决定。这些影响仅在车速低于每小时20英里时出现。在有信号灯控制的十字路口，当只有福特翼虎混合动力车组成平行车流时，最难被察觉。结果表明，有必要对影响盲人行人过马路决定的车辆特性进行更多的对照研究。
