| 摘 要： | 为了在区域内分析高等级路网交通状态,建立了一种区域高等级路网交通状态分析模型。首先分析路网结构并对路段的交通状态进行识别分类,建立在实时交通状态下的区域高等级路网模型;然后基于路网模型运用系统结构分析法建立路网交通状态分析模型,根据不同交通状态分析需求得到不同的交通状态可达矩阵,并对可达矩阵分层分析。通过实例表明：该模型能够有效地判别路网中节点的可达性和连通性,描述路网的交通状态时空变化规律,若通过及时发布信息,出行者可根据不同的信息需求来选择最优路径,避免大范围拥挤,从而提高整个路网的运行效率。

| Abstract: | In order to analyze traffic state of regional high-grade highway network,this paper researches on how to establish a model for analyzing.It firstly analyzes the structure of network,then recognizes and classifies traffic state of sections.After this,a model of regional high-grade highway network is established under the real-time traffic state.Based on this model,another model for analyzing the traffic state of network is established by using the method of system structural analysis.Though this model can ob... |
