摘要
对应用累计频率曲线法进行事故多发段判别时,加入动态步长法的思路进行了讨论,并应用实例对加入前后的判别结果进行了对比分析,旨在提高累计频率曲线法的判别精度。
This paper discusses the using of accident cumulative frequency curve method joined with dynamic step filtration method in accident prone location (APL) identification.Some examples are analyzed to show the before-after result of joining with dynamic step filtration method.The purpose is to improve the precision of accident cumulative frequency curve method.
