摘　　要：儿童行为因素是导致儿童交通事故的重要风险因素之一。由于儿童认知发展水平的局限,他们在穿越城市道路时会比成年人更容易犯错,因此需要通过一种有效的交通安全教育方法改善儿童行为从而降低风险。针对车速车间距组合的感知与判断、车辆临时停车导致的视线遮挡这两个关键情境,利用虚拟现实技术进行仿真,构建交通安全训练虚拟现实系统,培训儿童安全穿越城市道路。系统试用结果表明,学生在多次训练后过马路成功几率及安全意识均有所提升。将虚拟现实用于儿童穿越城市道路的情境仿真和训练,能增强儿童过马路能力。Children’s behavior factors are one of the important risk factors of children’s traffic accidents.Due to the cognitive development characteristics of children,they are more likely to make mistakes than adults in some scenarios in the process of crossing urban roads.Therefore,an effective traffic safety education method is needed to improve children’s behavior and reduce their risks of crossing urban roads.The research goal of this topic is to use virtual reality technology to simulate and construct the traffic safety training virtual reality system for educating children crossing urban roads in view of the two key scenarios of perception and judgment of vehicle speed and vehicle spacing and children’s sight blocked because of temporary vehicle parking.The system was put into local primary school trials,and the experimental results proved that students have a chance to cross the road after passing many trainings.Questionnaire survey shows that students’safety awareness has improved after receiving training.It proves that virtual reality used for children’s cross-city road simulation and training can enhance children’s ability to cross the road.
