【摘要】 在对交通规划的出行分布模型作了全面而深入探讨的基础上，提出了改进方案．指出增长系数法的各种模式均能得到相同的结果，并对此作了论证，提出了计算速度最快的模式．为机会模型法提供了一个参数标定的方法，为它的广泛应用打开了渠道，最后对重力模型法作了归纳和创新．更多还原

【Abstract】 This paper obtains an improved scheme, on the basis of discussion, of the trip distribution model of the Urban traffic planning. It also proves that various models of the growth factor method will lead to the same results. It provides an efficientst model, a parameter estimation method for the chance model and opens up a wide appication field. Finally, the gravity model method is concluded and some new ideas are brought out.更多还原
