与自动驾驶系统（ADS）及其与环境的相互作用相关的复杂性对其安全评估提出了挑战。驾驶里程数已被建议作为衡量技术成熟度的指标之一。然而，ADS遇到的经验或场景是一个更有意义的指标，并导致汽车行业和研究界转向基于ADSs的测试方法。各种场景生成技术已经被提倡，包括真实世界的数据分析，事故数据分析和通过系统的危险分析。虽然场景生成可以通过这些方法完成，但需要一种场景描述语言格式，该格式能够在具有不同使用要求的不同利益相关者（作为系统工程生命周期的一部分）之间交换场景。在本文中，我们提出了一个两级抽象的方法，场景描述语言（SDL）- SDL 1级和SDL 2级。SDL级别1是监管机构或系统工程师使用的更高抽象级别的场景的文本描述。SDL Level 2是一种正式的机器可读语言，可由测试平台（如仿真或测试轨道）接收。可以通过添加更多细节将SDL级别1中的场景转换为SDL级别2，或者通过抽象将SDL级别2转换为SDL级别1。
The complexities associated with Automated Driving Systems (ADSs) and their interaction with the environment pose a challenge for their safety evaluation. Number of miles driven has been suggested as one of the metrics to demonstrate technological maturity. However, the experiences or the scenarios encountered by the ADSs is a more meaningful metric, and has led to a shift to scenario-based testing approach in the automotive industry and research community. Variety of scenario generation techniques have been advocated, including real-world data analysis, accident data analysis and via systems hazard analysis. While scenario generation can be done via these methods, there is a need for a scenario description language format which enables the exchange of scenarios between diverse stakeholders (as part of the systems engineering lifecycle) with varied usage requirements. In this paper, we propose a two-level abstraction approach to scenario description language (SDL) – SDL level 1 and SDL level 2. SDL level 1 is a textual description of the scenario at a higher abstraction level to be used by regulators or system engineers. SDL level 2 is a formal machine-readable language which is ingested by testing platform e.g. simulation or test track. One can transform a scenario in SDL level 1 into SDL level 2 by adding more details or from SDL level 2 to SDL level 1 by abstracting.
