Quantifying the Influence of Road Geometric Parameters on Road Safety
 
Road safety depends on humans, vehicles, and highway conditions. These factors influence road safety separately or in combination. Despite these facts,the police report indicated that only a single cause of accident has been reported for a given accident in Ethiopia and the number of accidents that had been caused by road defect accounted around 1% of total accidents per year,which underestimates its contribution to road accidents. Beside these facts,only a few studies were carried out in Ethiopia on this issue. Even though dangerous road segments were identified and ranked along the same study area of this paper in our previous publication, Hawassa-Shashemene-Bulbula two-lane rural highway, the influences of road geometric parameters on road safety were not correlated along this study area. Therefore, it is imperative to clarify the relationship between the expected number of traffic accidents and the geometric conditions of the road under study to reduce accidents and provide safe driving environment. The main objective of this study was to quantify the influence of road geometric parameters on road safety. Using historical accident data, traffic data, and road data, the expected numbers of accidents were estimated by using the empirical Bayes (EB) method. Then,the expected numbers of accidents have been correlated with one or more road geometric parameters at a time. Accordingly, the identified dangerous road segments in the previous publication (DOI: 10.4236/jtts.2018.83009) were further analyzed to estimate the influence of road geometric parameters on road safety based on expected accident frequency. The result of the analysis shows that the radius of horizontal curve, superelevation, transition curve length, lane and shoulder widths were negatively correlated with the expected frequencies of accidents. 

道路安全取决于人员、车辆和公路状况。这些因素分别或综合影响道路安全。尽管存在这些事实,但警方报告显示,埃塞俄比亚发生的一起事故只报告了单一事故原因,每年因道路缺陷造成的事故数量约占事故总数的 1%,低估了这一点。它对道路事故的贡献。除了这些事实外,埃塞俄比亚在这个问题上只进行了少数研究。尽管在我们之前的出版物 Hawassa-Shashemene-Bulbula 双车道农村公路中沿着本文的同一研究区域识别并排列了危险路段,但道路几何参数对道路安全的影响在该研究区域没有相关性。因此,明确交通事故预期数量与所研究道路几何条件之间的关系,以减少事故发生,提供安全的驾驶环境势在必行。本研究的主要目的是量化道路几何参数对道路安全的影响。使用历史事故数据、交通数据和道路数据,使用经验贝叶斯(EB)方法估计事故的预期数量。然后,预期的事故数量一次与一个或多个道路几何参数相关联。相应地,进一步分析了先前出版物(DOI:10.4236/jtts.2018.83009)中识别出的危险路段,以基于预期事故频率估计道路几何参数对道路安全的影响。分析结果表明,水平曲线半径、超高、过渡曲线长度、车道和路肩宽度与事故预期频率呈负相关。(在线翻译)
