基于改进Logit模型的动态交通分配算法[EB/OL]
北京:中国科技论文在线
) 摘要: 将容量限制---增量加载交通分配模型和Logit模型相结合,提出一种分批加载并使用改进Logit模型进行概率选择的多路径交通分配方案
对交通量进行分批加载
这样一方面可加快分配速度,使其适用于大型网络的交通分配;同时较好地满足容量限制条件,以使交通分配结果更符合实际状况
最后以一个实际算例证明了该算法的可行性

) Abstract: This paper presented a Multi-path traffic assignment algorithm which based on Capacity constrain and modified Logit-model
The new model combined the strong poi -nts of Capacity constrain model and Logit-model
Speed of the Multi-path dynamic tra -ffic assignment model is largely improved and is enable to apply to large-scale networ -k
At the same time the model can meet constrains of capacity better
In the and, a sam -ple is used to prove algorithm feasibility and to show the traffic distribution result with the method more in line with actual traffic conditions
Keywords: Capacity constrain; Multi-path traffic assignment; modified Logit method 下载PDF阅读器 PDF全文下载: 初稿 ( 193 ) 作者简介: 通信联系人: 【收录情况】 中国科技论文在线: 王晓巍
