不确定需求条件下的交通平衡问题分析方法研究
, PP. 111-115
Keywords: 交通工程,点估计法,表达式分析法,不确定需求,交通平衡问题
Abstract:
对不确定需求条件下交通网络平衡问题的分析方法进行了研究。针对不同的需求情形,分别提出了求解交通平衡模型的基于需求点逼近的点估计法和基于模型的表达式分析法。首先给出了点估计法求解交通网络平衡问题的过程,研究了点估计法的局限性;然后,提出了求解交通网络平衡模型的表达式分析法,即从模型表达式出发,在需求分布为已知的条件下计算模型的解,包括模拟法、公式推导法和情形概率法,并以用户平衡模型求解为例,分别研究了各种方法具体的适用范围和求解过程。最后通过实例,对各种分析方法进行了对比分析。
