摘要
城市道路的路阻函数是交通研究中的关键点和难点,对交通分配起着至关重要的作用。本文先对城市道路路段阻抗函数进行细致的分析,通过实际调查的数据对该函数进行了验证。对信号交叉口的路阻函数进行了比较详细的分析,提出了隐性冲突点的概念,对信号交叉口阻抗函数中添加了与流向有关的心理参数项,并进行了分析和标定。
Resistance function of urban road is the key and difficult problem in traffic study. It plays a vitally important role in traffic assignment. This paper gives a specific analyze in urban road resistance function. And the function is proved with investigation data. The concept of recessive conflict point is brought forward as well. Moreover, psychological parameter is analyzed and added to the resistance function of the signal intersection.
