中文摘要：
以往研究多从中观的角度，将路口归入路段，但都未能对交叉口交通状态作重点分析。针对该问题，将路口交通状态划分为4个等级，建立了路口运行状态评价指标体系及相应的模糊综合评判模型，并结合一典型交叉口实例对其运行状态进行了评价分析，从而为评估城市交通拥堵、制定相应的交通管理和控制策略提供了一种有效的定量分析方法。
英文摘要：
Previous research put intersection into road sections more from the meso perspective, however, ignoring the effects of intersection to traffic network state. In this work, urban intersection traffic state is classified into four grades, intersection traffic state evaluation index systems and corresponding fuzzy comprehensive evaluation model were established, then the traffic states of one typical intersection was evaluated and analyzed. Accordingly, an effective quantitative analysis method was provided for evaluation of the urban traffic state, development of appropriate traffic management and control strategy.
