Abstract

We studied the relation between deaths due to traffic accident in India and geomagnetic activity indices: Kp, Ap, Dst and solar activity (SA) parameters, sun spot number, solar flare index (FI), coronal index (CI) and yearly average of cosmic ray intensity, observed during the period of 1989-2011. It is seen that rate of death by traffic accident are well correlated with these parameters. We have found large negative correlation with correlation coefficient of -0.84,-0.79 between rate of death by traffic accident and Kp and Ap indices; large positive correlation with correlation coefficient 0.79 rate of death by traffic accident and Dst index. Further good medium correlation with correlation coefficient of -0.56,-0.60.-0.56 has been found between rate of death by traffic accident and yearly average of sunspot number, solar flare index and coronal index respectively. A positive correlation with correlation coefficient of 0.69 between rate of death by traffic accident and yearly average of cosmic ray intensity was also obtained.

Key words: Sunspot numbers, solar flare index, coronal index, cosmic ray intensity, Ap index, Kp index, Dst index, traffic accident death.
