摘 要: 对高速公路诱增交通量的有关内容作了尝试性的探讨 ,主要明确了高速公路诱增交通量的定义 ,论述了诱增交通量的产生机理和基本特点 ;分析了高速公路诱增交通量的发展变化过程 ,根据其变化规律建立了定量计算的数学模型 ,并给出了模型标定的方法 ;同时 ,分别计算了成渝和京津塘高速公路的实际诱增交通量 ,采用实证归纳方法 。 This paper conducts trial discussions for the induced traffic volume on expressway,clarifies the definition of this traffic volume,explains its generation mechanism and the basic feature,analyzes its evolutions,establishes its mathematical model according to its changing laws,and comes up with the methods for model identification.The paper also calculates the actual induced traffic volume on Cheng Yu Expressway and Jing Jing Tang Expressway,and summarizes,with the help of induction of concrete examples,the changing features and the characteristic values of the induced traffic volume in the different areas.
