以事故率和冲突数作为评价指标,建立对公路平面交叉口安全的灰色理论评价方法,综合历史数据和现实数据,引入冲突分析快速、定量的特点,弥补事故分析周期长、数据缺失严重的不足。运用灰色理论方法,算法含义清晰、明确,评价结果更加全面、可信,为安全诊断和后续的改善工作找到重点,提供科学依据。经结果分析和对比,方法的有效性更强,适用性更广。
Taking the accident rate and the number of conflicts as the evaluation indexes, a gray theory evaluation method for highway intersections safety is established. Based on the historical data and the real data, the rapid and quantitative analysis of conflict analysis is introduced to make up for the long period of accident analysis and the serious lack of data . By using the gray theory method, the meaning of the algorithm is clear and definite, the evaluation result is more comprehensive and credible, and the key points for safety diagnosis and subsequent improvement work are provided, providing a scientific basis. The results of analysis and comparison, the method is more effective and more applicable.
