一个新的交通出行分布模型系列

交通出行分布预测是城市交通规划的一处重要环节，当今流行的重力模型法在预测中尚有不如人意之处，文中提出一种新的预测模型，意在提高出行分布预测的精度并使共操作方法比重力模型更加简便，在重力模型中，区与区之间的出行阻抗是建模中必备的资料，然而阻抗在实际应用中人们对其有着许多不同的理解，也不容易进行比较精确的标定，它影响了模型的精度和预测的功效。

New Series Trip Distribution Model

In the paper, we now put forward a new series in trip distribution model. The model requests only moderate accuracy about data of trip resistance in establishing the model and moderate worktime, but it has a better fitting accuracy than the Gravity model. This series model in the paper is very suitable for cities where the function of land--use often varies and especially for those cities just newly built.
