The aim of this study was to compare parents' expectations for their children crossing streets with children's actual crossing behaviours and determine how accurately parents judge their own children's pedestrian behaviours to be.
Using a fully immersive virtual reality system interfaced with a 3D movement measurement system, younger (7-9 years) and older (10-12 years) children's crossing behaviours were assessed. The parent viewed the same traffic conditions and indicated if their child would cross and how successful she/he expected the child would be when doing so.
Comparing children's performance with what their parents expected they would do revealed that parents significantly overestimated the inter-vehicle gap threshold of their children, erroneously assuming that children would show safer pedestrian behaviours and select larger inter-vehicle gaps to cross into than they actually did; there were no effects of child age or sex. Child and parent scores were not correlated and a logistic regression indicated these were independent of one another.
Parents were not accurate in estimating the traffic conditions under which their children would try and cross the street. If parents are not adequately supervising when children cross streets, they may be placing their children at risk of pedestrian injury because they are assuming their children will select larger (safer) inter-vehicle gaps when crossing than children actually do.
本研究旨在比较父母对孩子过马路的期望与孩子实际的过马路行为，并确定父母对自己孩子行人行为的判断准确程度。
使用与3D运动测量系统接口的全沉浸式虚拟现实系统，对年幼（7 - 9岁）和年长（10 - 12岁）儿童的过马路行为进行评估。家长观看相同的交通状况，并指出他们的孩子是否会过马路以及他们期望孩子过马路时的成功率。
将孩子的表现与父母对他们行为的期望进行比较发现，父母显著高估了孩子的车间距阈值，错误地认为孩子会表现出更安全的行人行为，并选择比实际更大的车间距过马路；孩子的年龄和性别没有影响。孩子和家长的得分不相关，逻辑回归表明二者相互独立。
父母在估计孩子试图过马路时的交通状况方面并不准确。如果父母在孩子过马路时没有进行充分监督，他们可能会使孩子面临行人受伤的风险，因为他们认为孩子过马路时会选择比实际更大（更安全）的车间距。
