Abstract:

针对美国HCM 2000基于车道组计算信号交叉口控制延误方法中对同一车道组内各车道使用不均衡情况的处理方式与实际情况不符合的问题，依托交叉路口实例分析了基于车道组和基于车道两种控制延误计算方法的差异，且对Webster延误计算公式以及排队论模型进行了探讨，分析了造成此差异的原因，得出了基于车道组和基于车道的两种控制延误计算方法的适用条件，并对普遍采用的控制延误计算方法及计算工具的开发提出了改进建议.研究成果对于准确计算信号交叉口控制延误、指导相应的辅助计算工具开发具有参考价值.

Key words:signalized intersection; control delay; unequal lane utilization; lane group based; lane
