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的影响,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了论述,进一步给出了多交叉口组合关联度的定义与计算公式,并制定了新的基于关联度分析的协调控制子区划分原则.
By analyzing the influences of the intersection distance, the traffic section volume and the signal timing parameters on the correlation between two neighboring intersections, a new traffic parameter, neighboring intersection correlation degree, is put forward to quantitatively describe the correlation between two neighboring intersections, and the corresponding calculation method is proposed. Then, the rationality of the parameter is analyzed and the definition and calculation formula of the multi-intersections combinatorial correlation degree are presented. Some new principles for the coordinative division of traffic control subareas are given based on the correlation degree analysis.
