摘　　要：分析国内现有的3种典型的信号交叉口通行能力计算方法,阐述有序加权平均算子理论及其赋权方法,以信号交叉口的通行能力为决策因子,建立了一种信号交叉口通行能力优化算法。通过对南京市某一信号交叉口进行实际调查并进行通行能力计算,结果表明:经有序加权平均算子理论综合加权优化后的信号交叉口通行能力与传统计算方法相比,具有更高的精度。By analyzing the existing three typical signal intersection capacity calculation methods in China, expounding the ordered weighted averaging operator theory and the empowerment approach, this study established an optimizing model which took signal intersection capacity as the decision-making factors to calculate the capacity. Through investigating a signal intersection in Nanjing and calculating the capacity, it shows that the capacity which was optimized by the ordered weighted averaging operator has a higher accuracy than the traditional calculation methods.
