摘要
以新疆乌鲁木齐市机场高速公路采集的数据为基础,在分析新疆降雨特点的前提下,运用非线性回归的方法,对比分析了不同降雨强度在不同车道上的交通流特征的规律。研究表明:随着降雨强度的增加,速度、流量减少的程度越大;同强度降雨对高速车道的影响比低速车道的大,但呈现的规律表现基本一致。在此基础上,对实采数据拟合,得到了速度与密度、密度与流量、流量与速度的关系图。
Based on the data collected from Urumqi Airport Highway in Xinjiang City, according to the characteristics of rainfall in Xinjiang are analyzed, the characteristics of traffic flow in different lanes are compared with the method of nonlinear regression. The research shows that ： with the increase of rainfall intensity, the speed and the flux decrease, and the influence of the same intensity of rainfall on the speed of the high speed lane is bigger than that of the slow lane, but the performance of the same law is the same. On the basis of this, the relationship between velocity and density, density and flow rate, flow rate and velocity is obtained.
