山区双车道公路事故预测模型路侧危险度事故修正系数研究

在综合事故预测模型的研究和应用中,包括基础模型、事故修正系数、标度程度、EB函数应用等几个部分。事故修正系数的研究和使用可以使事故预测模型应用时包含更多、更可靠的影响要素信息。针对我国山区双车道公路两侧路侧危险度的实际情况,对路侧危险度对安全的影响规律做了具体分析,分别建立了针对全部事故预测模型、碰撞事故预测模型和路侧事故预测模型的我国双车道公路路侧危险度事故修正系数函数。

A Study on Accident Modification Factor About Roadside Hazard Rating in Accident Prediction Models for Two-Lane Highway in Mountainous Area

There are base models,accident modification factors,calibration procedure,Empirical Bayes in the study and application of accident prediction models.The accident prediction models can include more factors about highway safety with the using of accident modification factors.The characters between roadside hazard rating and highway safety based the fact of the roadside hazard characters in the two-lane highway in China are analysed.So the accident modification factors of roadside hazard rating for accident models about all accidents,collision accidents and roadside accidents are made.
