该文系统地回顾了透水性沥青路面对道路安全影响的研究,采用Meta-分析方法对6篇文献成果进行分析,共包含透水性沥青路面对交通事故率影响的18项评估,研究发现,透水性沥青路面对道路安全并没有明显影响;各项影响的总体评估表明交通事故率变化很小,与传统水平没有显著差异。此外,文章还回顾了透水性沥青对与交通事故有关的9种危险因素影响的研究文献,发现对其中4种因素产生有利影响,3种产生不利影响,2种没有影响;危险因素的变化对交通事故的净效应是不可预测的。总之,已发表的关于透水性沥青路面对道路安全影响的研究文献并没有得出明确的结论,研究质量不高且结果不一致。
This paper systematically reviews the impact of water-permeable asphalt pavement on road safety research, the use of Meta-analysis of six literature results were analyzed, including water-soluble asphalt pavement impact on traffic accident rate of 18 assessments, the study found , The permeability of asphalt pavement has no obvious effect on road safety. The overall assessment of the impacts shows that the traffic accident rate has little change and no significant difference from the traditional level. In addition, the article reviews the literature on the impact of water-permeable bitumen on nine risk factors associated with traffic accidents and found that four of them had a beneficial effect, three had adverse effects and two had no effect; and the risk factors were changed The net effect of traffic accidents is unpredictable. In summary, the published literature on the impact of water-permeable asphalt pavement on road safety has not led to definite conclusions, poor quality of research and inconsistent results.
