摘要
以上海城市快速路交通数据采集系统采集的大量实测交通数据为分析对象,提出了一种基于统计学原理的自由流车速确定方法。介绍了自由流车速的定义,基于统计学原理的自由流车速确定方法、步骤。对计算结果进行正态分布检验和稳定性分析。这一车速确定方法得到的城市快速路自由流车速可为进一步研究城市快速路的有关问题提供很好的基础。
Through analysis of a large amount of site-detected traffic data collected by Shanghai Urban Fast Road Traffic Data Collection System,the method and steps are proposed to determine the free-flow vehicle speed using principles of statistics,including its definition.After normal distribution verification of the result from calculation and stability analysis,the free-flow speed thus obtained can be a good foundation for further study on urban fast roads.
