摘要:

为理清道路交通安全反事实仿真发展脉络,进一步推动反事实仿真技术的应用,从反事实仿真技术基本原理出发,梳理反事实仿真5个阶段,比较事故场景与自然驾驶场景的差异,讨论仿真模型在驾驶人避险行为、路面条件、事故损伤与事故风险结合等方面的不足,归纳、对比仿真过程、评估指标技术要点;并在分析反事实仿真技术适用性的基础上,归纳该技术的发展趋势。结果表明:驾驶员因素的不确定性限制了反事实仿真的应用领域,目前该技术更适于碰撞、避险阶段的交通安全评价与分析。

Abstract:

In order to clarify the development of counterfactual simulation and further promote application of counterfactual simulation technology, five stages of counterfactual simulation were sorted out, the differences between accident scenarios and natural driving scenarios were compared, the shortcomings of simulation models in the aspects of drivers' avoidance behavior, road conditions, accident damage and accident risk combination were discussed, and the simulation process and technical key points of evaluation indicators were summarized and compared based on the basic principle of counterfactual simulation. In addition, the development trend of counterfactual simulation technology was summarized based on the analysis of its applicability. The results show that the uncertainty of drivers limits the application field of counterfactual simulation and this technology is more suitable for evaluation and analysis of traffic safety during collision and hedging stages currently.

Key words: traffic safety, counterfactual simulation, safety assessment, simulation model, applicability
