Application of Gravity model of double limit in traffic distrbution prediction of XingTai traffic planing

摘要

Traffic distribution is an important part of four phases method. Many ways are applied in the work. Among these ways, growth ratio way and Gravity model way are often adopted. Through intrduction the Gravity model and analysis on charactics, the emphasis is on Gravity model by double limtit. By means of analysis on choosing and branding model, it concludes that it is feasible in traffic distrbution prediction which the planing area has great changes during the planing phase.
