两种运行车速预测模型的研究与应用

Study and application of two operation speed predication model

分析比较了国内外两种车速预测模型,并分别采用美国交互式道路安全设计模型(IHSDM)的车速预测模型以及我国《公路安全性评价指南》的车速预测模型对某高速公路进行了运行车速预测计算,对计算结果进行了分析研究和比较,对下一阶段公路安全评价和提出限速标准具有重要意义。

Two operation speed predication models at home and aboard were analyzed and compared, the operation speed of some express high- way was predicated calculation with American Interactive Highway Safety Design Model （IHSDM） and Chinese speed divining model of Highway safe evaluation index. The calculation result was analytic studied and compared, which was significance to next highway safe evaluation and speed rising norm presentation.
