As far as the author is aware no statistics of traffic accidents were so far concerned with the problem of a possible correlation of their frequency with the position of the moon, i.e. the lunar phase. Sudden cardiovascular deaths and some meteorological parameters (mean precipitation, atmospheric pressure and temperature) have this correlation and in most instances it is highly significant.
The authors processed data pertaining to a total of 60,142 traffic accidents in the former South Moravian region in 1983, 1984, 1990, 1991 and 1992. The number of accidents on every particular day was classified according to the lunar phase. It was revealed that the frequency of accidents increases twice in the course of the lunar cycle (i.e. in the semilunar stages). The first increase is on the second and third day following new moon (t = 1.89 < 1.96 which is closely beneath the 5% level of statistical significance, p > 0.05). The second increase is more prolonged and more marked and starts already on the first day before full moon and persists after full moon with a maximum on the second day after full moon (t = 1.32 < 1.96, which again is beneath the 5% level of statistical significance, p > 0.05). The curve of the frequency of traffic accidents follows practically the same course as the curve of changes of atmospheric precipitation except for the day before full moon and the day after full moon.
The revealed semilunar increase of traffic accidents is probably associated with the bi-phasic change of atmospheric precipitations with their increase closely after new moon and after full moon. However, one day before full moon the atmospheric precipitation is low and the increase in the accident rate on these days might be explained by the effect on the human factor, i.e. psychosomatic changes during the period near the full moon.
就作者所知，目前尚无关于交通事故统计数据涉及事故发生频率与月球位置（即月相）之间可能存在的相关性问题。突发心血管死亡与一些气象参数（平均降水量、气压和温度）存在这种相关性，并且在大多数情况下相关性非常显著。
作者处理了1983年、1984年、1990年、1991年和1992年原南摩拉维亚地区总共60142起交通事故的数据。根据月相将每天的事故数量进行分类。结果显示，在月周期（即半月阶段）过程中，事故频率会增加两倍。第一次增加发生在新月后的第二天和第三天（t = 1.89 < 1.96，略低于5%的统计学显著性水平，p > 0.05）。第二次增加持续时间更长且更为明显，在满月前一天就已开始，并在满月后持续，在满月后第二天达到最大值（t = 1.32 < 1.96，同样低于5%的统计学显著性水平，p > 0.05）。交通事故频率曲线与大气降水量变化曲线几乎遵循相同的趋势，只是在满月前一天和满月后一天有所不同。
所揭示的交通事故半月增加现象可能与大气降水量的双相变化有关，降水量在新月后和满月后会迅速增加。然而，在满月前一天大气降水量较低，这些日子事故率的增加可能是由于对人为因素的影响，即在满月附近时期的身心变化。
