| 摘 要： | 重力模型是交通分布预测中应用最广泛的模型之一，其参数需要根据对象的具体情况进行标定。理论证明，利用最小二乘法、多元线性回归法、试算法分别标定不同的重力模型，可得出针对于不同重力模型的标定方法。

| Abstract: | Gravity model is one of the most widespread models used in the traffic distribution forecast Parameters of gravity model should be calibrated according to the situation of the object. This paper calibrates the different gravity models with the least-square regression and multiple linear regression and trial and error procedure, and concludes the proper choice by comparing the result. |
