摘　　要：城市道路网络模型及其算法是城市道路网络分析和分配的基础。本文首先分析了交通管制条件下原有城市道路网络模型和算法的不足,在此基础上提出一种改进模型和算法,并给出算例。这种改进的模型和算法能较好地满足实际分配的要求,在交通规划、交通管理和交通流模拟中都有着十分广阔的应用前景,且已经被成功地应用于郑州市综合交通规划中。Urban road network model and assignment algorithm are the basis of urban road network analysis and traffic assignment, This paper first analyses the shortcoming of old model and algorithm under traffic control condition, then proposes a new improved model and algorithm, which can make up for the shortcoming, and can satisfy the demand of urban traffic assignment. This article also presents an example of the new model and algorithm. The new model and algorithm can be applied to traffic planning, traffic management planning, and traffic flow simulation, and it has already been successfully applied to the'Comprehensive Traffic Planning of the City of Zhengzhou'.
