相邻交叉口关联度分析研究及其应用

通过分析相邻交叉口间距、路段交通量、以及交叉口信号配时参数对相邻交叉口关联性强弱的不同影响，提出一个对相邻交叉口之间关联性进行定量化描述的交通参量——相邻交叉口关联度，并对其计算方法与科学合理性进行详细论述。利用相邻交叉口关联度分析方法，进一步给出多交叉口组合关联度的定义与计算公式，并制定新的基于关联度分析的协调控制子区划分原则，为建立定量化分析的控制子区动态划分理论提供了一条科学有效的新途径。

Analysis and Research on the Correlation Degree of Neighboring Intersections and Its Application

By analyzing the different influences of neighboring intersections’ distance, traffic section volume and signal timing on correlation between neighboring intersections, a new traffic parameter named correlation degree of neighboring intersections is put forward. This new traffic parameter can describe the correlation between neighboring intersections quantitatively, and its calculation method and rationality analysis are discussed in detail in this paper. Using neighboring intersections’ correlation degree analysis method, the definition and calculation of multi-intersections’ combinatorial correlation degree are further presented, and some new principles for division of traffic control sub-area based on correlation degree analysis are given. A new scientific approach that contributes to establishing the dynamic division theory of traffic control sub-area upon quantified analysis is effectively provided.
