交叉口转向交通量调查布点方法研究

Study on the Survey Point Layout of Turning Traffic Volum e of Intersection

分析了现状交叉口转向交通量观测方法的不足 ,提出了通过观测进出口交通量和部分易观测转向交通量来推算各个转向交通量的精确算法 。

The turning traffic volumes of major intersections are the fundamental data of present traffic evaluation, management improvement of intersection and traffic forecasting. The shortcomings of the survey method that is widely used nowadays were pointed out in this paper. And a new precise calculation method to estimate the turning traffic volumes was put forward. This method merely needs traffic volumes of correlative segments and a few turning traffic volumes those are easily surveyed. Finally the method was proved.
