大城市快速路网布局方法研究

Study on the Layout Method of Expressway In a Big City

针对我国大城市干道网布局主要以环放射式为主的现状,从计算数学的角度出发,提出了主要面向环放射式路网结构的基于交通单元划分的大城市快速路布局规划方法,并给出了快速内环半径计算和交通单元规模确定的方法。

To ease the growing pressure on urban traffic, the paper aiming at the phenomenon that the majority of big city in our country had built ring-radial road network,bring up the layout method of urban expressway network,which based on traffic unit deviding by numerical mathematics method. And provides the methods of in-ring expressway radius calculate and scope of traffic unit confirm.
