摘　　要：在交通工程学范畴,车速不仅反映了车辆的行驶状态,还反应了交通设施的服务水平。以分布特征为切入点,可以深入对交通流特性进行研究。本文基于现有的研究成果,从车速分布与交通流参数的关系、车速分布特征、影响因素及其与交通安全的关系四个方面归纳分析了目前关于交通流车速分布的研究,并从车速离散性的角度提出了提升道路交通安全的思路,希望能够为后续车速分布内容的研究和交通管理决策部门提供一定的借鉴和参考。In the field of traffic engineering, vehicle speed not only reflects the driving state of the vehicle, but also reflects the service level of transportation facilities. With the distribution characteristics as the starting point, it is possible to study the characteristics of traffic flow in depth. Based on the existing research results, this paper summarizes and analyzes the current research on the speed distribution of traffic flow from the four aspects: the relationship between speed distribution and traffic flow parameters, speed distribution characteristics, influencing factors and the relationship with traffic safety. From the perspective of speed dispersion, this paper puts forward the idea of improving road traffic safety, hoping to provide certain reference for the subsequent research on the content of speed distribution and traffic management decision-making department.
