| 摘 要： | 选取代表集中趋势的平均车速、15%位车速、85%位车速,代表离散程度的速度标准差作为车速分布特性的参数。结合4条普通公路速度调查结果,对道路因素、车辆因素、交通流因素与速度分布特性参数的关系进行了研究,通过实测统计数据图形的变化分析了各种因素对速度分布特性的影响。

| Abstract: | Data distribution characteristic can be measured and described in three ways： one is the central tendency of distribution,the other is the discrete degree of distribution and the last is the shape of the distribution.The average speed,15th percentile speed,85th percentile speed and the speed standard deviation are selected as the speed distribution parameters on behalf of central tendency and dispersion degree.Investigation results are used to study the relationship between speed distribution parameters and road conditions,vehicle factors,traffic flow.The impact of different factors on the parameters is analyzed through the line chart. |
