摘　　要：在对现有研究成果进行分析与总结的基础上,基于服务水平、路段及交叉口通行能力重新定义交通网络储备容量.在确定限制因素、交通分配方法及阻抗函数后,建立交通网络储备容量模型及相关算法,并运用Trans CAD软件计算某市区的交通网络储备容量,将所得结果与时空消耗法所得结果进行对比分析,验证了所建立的模型在交通网络储备容量研究领域具有一定的实用价值.Aiming at traffic network reserve capacity, the relevant definitions and influence factors are formula- ted, and the service level, road traffic capacity and intersection traffic capacity are determined as the limiting factors of traffic network reserve capacity ceiling. A traffic network reserve capacity model and relevant algorithm are proposed, and the model is testd through a medium-sized network. TransCAD software is applied to estimate the traffic network reserve capacity, and it compares the data with the data by the widely used space- time consummation method, which verifies the practical applicability of the proposed model.
