摘要
从影响交通客流分布的最主要因素——人口、能耗、区域面积出发,提出交通质量的概念,并基于它提出了新的交通发生(吸引)模型,参照万有引力定律对重力模型进行了改进。用实例将预测模型与传统的预测模型相比,说明模型的可行性和有效性。
In view of the major factors influencing distribution of tragic flow, such as population, energy consumption, regional area, etc., this paper gives the concept of tragic quality, based upon which, it introduces a novel traffic occurrence （attraction） model. With the reference of the law of universal gravitation, the gravity model is improved. It gives practical instances to compare the forecast model with conventional forecast model and illustrates the feasibility and validity of this model.
