This study examined gap choices and crossing behavior in children and adults using an immersive, interactive bicycling simulator. Ten- and 12-year-olds and adults rode a bicycle mounted on a stationary trainer through a virtual environment consisting of a street with 6 intersections. Participants faced continuous cross traffic traveling at 25 mph or 35 mph and waited for gaps they judged were adequate for crossing. Children and adults chose the same size temporal gaps, but children left far less time to spare between themselves and the approaching vehicle when they crossed the intersection. Relative to adults, children delayed in getting started and took longer to reach the roadway. Discussion focuses on developmental changes in how children coordinate self movement with object movement.
本研究使用沉浸式交互式自行车模拟器，考察了儿童和成人的间隙选择及穿越行为。10岁和12岁的儿童以及成年人骑着安装在固定训练器上的自行车，穿过一个由一条有6个十字路口的街道组成的虚拟环境。参与者面对以每小时25英里或35英里速度行驶的持续交叉车流，等待他们认为足以穿越的间隙。儿童和成人选择的时间间隙大小相同，但儿童在穿越十字路口时，给自己和驶来车辆之间留出的备用时间要少得多。相对于成年人，儿童起步延迟，到达道路所需的时间更长。讨论集中在儿童如何将自身运动与物体运动进行协调的发育变化上。
