摘要： 在比较国内外现有事故多发位置鉴别方法的基拙上，通过对我国312国道某路段事故交通状况和事故统计资料的分析，提出了适合此路段的事故多发位置的鉴别方法—累计频率法，并在实际应用中从综合考虑各种交通安全评价因素的角度出发，基于当量和数理统计的理论对此方法进行了改进.在应用实例中，详细论述了改进后的应用原理和步骤，对比分析了前后两种不同的鉴别结果.应用结果表明该方法改进后鉴别出的事故多发位置更为准确，而且考虑了事故多发位置道路改造的经济性，在我国项目级事故多发位呈的鉴别中更具有现实意义.

Abstract: On the basis of comparing the black-spots identification methods at home and abroad, by analyzing the accident statistical data of national road 312, the paper puts forward the accident cumulative frequency method that can find the black-spots in the road, and make some improvement considering various comprehensive traffic safety factors. On the application case analysis，this paper introduce its uses and compare two results using the different methods. Application results show that the improved methods have the advantages of precision location and economical efficiency, so it is more practical in the identification of black-spots in China.

Key words: black-spots, identification, accident cumulative frequency method, equal quantity
