Possible influence of space weather changes on dynamics of traffic accidents in middle latitudes

We describe the results of joint studies to reveal a possible effect of space weather variations on the dynamics of traffic accidents in middle latitudes. We arrived at the conclusion that impulsive geomagnetic disturbances (storms) affect the number of traffic accidents more significantly than gradually changing background geomagnetic activity. The probable cause of this is the retarded or inadequate human brain's reaction. We also found a high correlation between cosmic ray activity (neutron flux) on the Earth's surface and the number of traffic accidents. Spectral analysis has revealed certain periodicities in the dynamics of traffic accidents, well-known in solar-terrestrial physics.
