Recent studies of the relationship between the speed of traffic and road safety, stated as the number of fatalities and the number of injury accidents, are reviewed and their results synthesised by means of meta-analysis. All studies were based on data fully or partly for years after 2000. Previously proposed models of the relationship between the speed of traffic and road safety, including the Power Model and an Exponential Model, are supported. Summary estimates of coefficients show that the relationship between speed and road safety remains strong. The Power Model and the Exponential Model both fit the data very well. The relationship between speed and road safety is the same at the individual driver level as at the aggregate level referring to the mean speed of traffic.
最近的研究探讨了交通速度与道路安全之间的关系，以死亡人数和受伤事故数量作为衡量标准，并通过荟萃分析对其结果进行综合。所有研究均基于 2000 年后的数据，这些数据全部或部分来自当年。此前提出的交通速度与道路安全关系模型，包括幂模型和指数模型，得到了支持。系数的汇总估计表明，速度与道路安全之间的关系仍然很强。幂模型和指数模型都非常适合这些数据。速度与道路安全之间的关系在个体驾驶员层面和总体层面（指交通平均速度）上是一致的。
