摘要
为研究影响城市道路交通事故的主要因素,提出了灰色关联系统宏观影响预测方法。从人、车、路综合环境整体观点出发,结合城市交通事故的自身特点,建立了交通事故影响因素预测模型,通过EXCEL图表工具分析各影响因素与道路交通事故的关系,并应用灰色理论模型计算各影响因素的灰色关联度。以城市交通事故调查和统计资料为基础参考对象,对预测模型进行了实例验证。结果表明,所建模型可行、有效,能较好地预测交通事故各影响因素相互关系及主要影响因素,为交通管理部门事故预防提供了参考对策。
Macroscopic influencing prediction model of grey correlation system was presented to re- search the main factors that affect urban traffic accident.Concerning the overall environmental perspective of people ,automobile ,and road as well as the distinctive characteristic of urban traffic accident,the predic- tion model of factors contributing to traffic accident was proposed.EXCEL software was applied to analyze the relations between the influencing factors and traffic accidents with grey theoretical model adopted to calculate the correlation grade among different factors. The prediction model was also validated through ex- amples on the basis of the investigation of traffic accident and the relevant statistics.The results show that the model is applicable and efficient in forecasting the main factors and the relations between them, thus providing reference for traffic administrative department to avoid traffic accidents.
