| 摘 要： | 对城市快速路车头时距分布的特征进行了详细分析，将分布曲线划分成反映不同交通情况的区域，以此为基础对交通流基本特性和理想状态下的车头时距提出假设。使用q-指数形式函数对分布曲线进行非线性回归拟合，并应用叠加统计变量的概念建立了车头时距的分布模型，并能够很好地从交通流基本特性出发解释分布陷线的形状特征。

| Abstract: | This paper analyzes the characteristics of headway distribution for urban expressway traffic.The distribution curve obtained from empirical data is divided into four regions which reflect different microscopic situations,and assumptions are made to obtain an idealized traffic situation,of which the distribution curve is fitted using q-exponential forms.Based on the concept of superstatistics,a model linking the basic characteristics of traffic flow to the headway distribution is proposed,which gives a good ... |
