Analysis of the Ring Road Tendency Influencing Factors on Route Choosing : A Case Study of the Third Ring Road in Beijing

21世纪以来，北京的三环路、四环路周边也形成了新的办公业集聚现象。

Since the21st century , Third Ring Road and Fourth Ring Road in Beijing has developed a new around office industry center .

采用北京市三环路检测断面测得的交通数据，验证所提出的算法是有效的。

The traffic data from a measured section of Beijing 's third_wreath road has been adopted to verify the algorithm presented in the paper to be effective .

结合城市环路的交通运行特性，构建了基于卡尔曼滤波的交通流短时预测模型，并根据北京市三环路的实际数据对模型进行验证。

In accordance with the traffic characteristics of urban ring road , a model of dynamic real-time forecasting based on Kalman filter is proposed , and the traffic flow data of Beijing third ring road are explored to test the validity of the model .

但是，以北京为例，三环路以外的地区开始出现蔓延。

But beyond the third ring road in Beijing , the urban sprawl begins .
