浅析美国公路安全设计模型(IHSDM)的应用

Application of American Interactive Highway Safety Design Model(IHSDM)

美国联邦公路管理局(FHW A)开发的交互式公路安全设计模型(IHSDM)自推出以来,以其先进的理念和可定量操作性在很多国家和地区得到了应用。在我国,已经对IHSDM有所关注,但并无验证性的使用结论。针对此现状,结合试例,对IHSDM的使用进行了详细的介绍,并将IHSDM的评价结果与经验性的安全预测相比较,得出了有益的结论;同时,也指出了IHSDM在我国实际应用中尚需改进的方面,旨在从路线线形设计的角度去提高公路的安全性。

Interactive Highway Safety Design Model （IHSDM） developed by FHWA has widely used in many countries and regions for its advanced concepts and quantitative analysis ever since its appearance. In China, IHSDM has already been touched, but there are still lacks of probative application and tests. In view of present situation, this paper takes an example to introduce the method of using IHSDM and then compares the IHSDM safety evaluation report with the experiential forecast of the example highway project, and finally gets the positive conclusions. Meanwhile, this paper also points out many aspects of IHSDM to be improved for its application in China. The purpose is to improve the highway safety by the way of highway geometric design.
