摘　　要：城市道路网络容量是判断现状城市道路网是否处于一种平衡稳定状态的重要决策变量。在对路网容量影响因素进行分析的基础上,将路网容量计算方法按照微观和宏观2个层面划分。针对研究路网容量存在的问题,提出一种新的基于出行者随机路径选择的研究路网容量方法,为今后深入研究在复杂道路条件下的路网容量提供科学理论依据和技术路线。Urban road network capacity is a vital decision-making variable which is used to judge whether or not current situation of the urban road network is in a balanced and steady state. Based on the analysis on influence factors of road network volume, calculating methods of road network capacity are divided into two aspects： microscopic and macroscopic. According to the issues of research on the road network capaci- ty, a new study approach is put forward based on stochastic user route choice behavior and provides a scientific theoretical basis and a technology route for further research on the road network capacity under the complicated road condition.

关 键 词：城市道路网容量 路径选择行为 双层规划 随机用户均衡
