摘　　要：重力模型法是交通规划课程交通分布预测一章的主要教学内容。目前重力模型法的教学多侧重于公式计算,对模型优缺点和实际应用效果的讲授比较欠缺,教学内容与研究前沿存在脱节。2012年在Nature发表的“辐射模型”弥补了重力模型的几个缺陷,引发了交通分布预测领域的新一轮研究热潮,然而也有研究指出辐射模型在城市区域的应用效果反不如重力模型。文章以辐射模型为切入点,提出若干教学改革建议,旨在拓展重力模型法教学内容,培养学生的科学批判思维。Gravity model method is the main teaching content of the“traffic distribution prediction”chapter in the course of transportation planning.At present,the teaching content of gravity model method mostly focuses on formula calculation.The introduction of the advantages and disadvantages of the model and its actual performance is relatively lacking,and the teaching content lacks connection with research frontier.The radiation model published in Nature in 2012 can solve several shortcomings of the gravity model and triggered a new wave of research in the field of traffic distribution prediction.However,there are some studies indicating that the performance of radiation model in urban areas is not as good as the gravity model.This article takes radiation model as the starting point and puts forward some teaching innovation suggestions,aiming to expand the teaching content of the gravity model method and promote students'scientific critical thinking.
