摘要: 分析1951—2009年间的中国交通事故死亡人数和太阳黑子数的有关资料, 用交叉小波、整体平均经验模式分解、相关分析等数学方法来探讨太阳长期活动统计上对交通事故死亡人数的 影响。结果表明:中国交通事故死亡人数与太阳活动的11年周期活动存在具有统计意义的正相关关系,严重交通事故的发生的确受太阳活动的影响。

Abstract: The relationship between death population of road traffic accidents and solar activity was investigated through ensemble empirical mode decomposition analysis, cross-correlation analysis, cross-wavelet analysis, and etc., which was based on the information of yearly mean sunspot number and annual death population (DP) of road traffic accident events in China from 1951 to 2009. The results obtained show that DP is statistically positively correlated with the 11-year-cycle solar activity. DP is not only closely related with human activities, but also affected by solar activity indeed.

Key words: traffic engineering, traffic accident, traffic safety, solar activity, correlation analysis
