摘　　要：阐述了一种将交通容量最大化的优化模型，考虑固定OD特性条件、交通守恒条件、路段容量条件、交通服务水平条件等不同约束条件，将其分为单O-D模型开始（单向）、单O-D模型（双向）、多O-D模型（多个出发点O，多个接收点D）和更为复杂的模型，找到优化目标和约束条件建立最大化交通容量的模型，并以西安市长安区为例具体计算其交通容量。The article describes a optimization model of traffic capacity maximization, considering the fixed OD conditions, traffic conditions, the conservation of road capacity conditions, the level of traffic service conditions, and other different constraint conditions, which can be divided into single O-D model （one-way）, single O-D model （BI）, O-D model （a starting point O, a plurality of receiving points D） and more complex models, in order to find the optimization objectives and constraints to establish maximum traffic capacity model. AT last, Taking Chang＇an District city of Xi＇an as an example to calculate the traffic capacity.
