道路交通事故与路况关系研究

Study on the Relationship between Accidents and Road Conditions

通过对山东省４２００ｋｍ公路、近２４００起各级事故的调查研究，阐述了各等级公路的交通事故率与路况关系的研究方法，论述了事故模型的影响因素、事故的调查和整理，给出了低等级公路事故率的预测经验公式；对如何建立高等级公路事故模型提出了建议。

This paper discribes the survey of nearly 2400 accidents on highway sections of more than 4200 kilometers. The method of study relationship between accidents and road conditions is summarised. The paper also deals with the factors which affect accident model as well as the sorting out of survey data. The empired equations of the pridiction of accident rates on lower class roads and the proposal on how to set up the accident models on higher class roads are present.
