摘　　要：提出了基于交通小区用地性质的交通需求模型建立方法,对该方法的基本原理、建模过程和可行性进行了阐述,针对传统交通需求的不足,用遗传算法进行模型的标定和求解来改进。在实例分析中,通过交通分配数据证明了该建模方法的精确性和有效性。In this paper, the traffic demand modeling method based on the land use function of the traf- fic zones is put forward, at the same time, the basic principle, modeling process, and feasibility of this method is clearly expatiated. Further more, the improvement advising to demarcate the modeling parameters and to solve the model with the genetic algorithm to the disadvantages in the conventional traffic model is advanced in this method, at the end of the paper, the instance analysis is set to prove the accuracy and validity of this modeling method.
