摘　　要：驾驶人是影响道路交通安全的主要原因,而使用汽车驾驶模拟器模拟危险的交通环境,对驾驶人进行培训可以有效提高驾驶人的应急操作技能和安全意识水平,对于减少和预防道路交通事故的发生具有重要意义。以2000～2010年道路交通事故数据为基础,分别从人、车、路以及事故形态进行统计分析道路安全影响最大的因素,获取典型的动态交通场景。并考虑城市道路环境的复杂性和多样性,选取发生在城市道路场景中的1种类型动态场景-公交站台行人过街作为案例,采用虚拟现实技术完成这一动态交通场景的设计和实现。Human is one of the most important reasons influencing road traffic safety.Therefore,improving drivers' traffic safety awareness and emergency operation skills is of great significance to reduce and prevent traffic accidents.In this paper,the driving simulator was used to simulate dangerous traffic environment to make drivers experience the harm of illegal driving in virtual traffic scenarios.Through this driver training,the drivers' safety awareness could be effectively improved.Based on 2000-2010 road traffic accident data from several aspects such as human,vehicle,road environment and accident form,the greatest impacts of traffic safety were selected to make up the typical dynamic traffic event.For the complexity and diversity of urban road environment,one type of dynamic events in city road scene was selected as a case,which is the conflict between the main vehicle and pedestrians in front of parking bus when pedestrians crossing street on the main road in city.The virtual reality technology was used to achieve it.
