| 摘 要： | 引入交通网络层次性这一基本特征来研究面向交通网络结构优化的配流算法.在充分分析算法的实践与理论基础后,定义了层次因子,并利用层次因子来计算最短路径、路段似然和路段权重;设计了基于Dial算法的交通网络结构优化算法.实例研究表明,所设计的算法可以通过将网络层次状况控制在合理范围内来有效地调节和优化交通网络资源配置,相对于Dial算法而言具有找到更优网络结构的灵活性.

| Abstract: | Hierarchical property of transport network as a common phenomenon has for the first time been introduced to study the transport network structure optimization oriented algorithm for traffic assignment.A definition of hierarchy factor was presented after the analyses,from practical and theoretical aspects,of bases for algorithm design.Hierarchy factors were then applied to compute shortest paths,link likelihoods,and link weights.All of the aforementioned investigations contributed finally to the design of a ... |
