【摘要】 针对道路安全审计中如何量化评价线形的设计质量这一重大技术问题,在分析国内外相关研究及实际调查研究的基础上,构造了高速公路线形设计质量量化评价模型,找出了模型量化评价值与亿车公里事故率之间的内在联系,充分验证了评价模型的适应性和有效性,最后给出了高速公路线形设计质量评价标准.更多还原

【Abstract】 The paper aimed at the important technique problem of how to quantify the evaluation of quality in line design during road safety audit.Based on analyzing the researches at home and abroad,and practice investigations,we structured the quantity evaluation model of line design quality in freeway,and have found out the inherence contact between the cost of quantity evaluation model and accident rate per 100 million vehicle kilometers.The paper validated thoroughly the adaptability and validity of the model.Finally it presents the evaluation standard of freeway line design.更多还原
