clusters. The same changes are observed in the spatial variability of coldspots from monsoon to nonmonsoon
period. While analyzing spatial pattern of accidents near to educational institutions, the hotspots
are concentrated in Kowdiar –Vazhuthacaud stretch, Vattiyoorkavu and Thirumala regions. At the same
time the accidents near to religious places show isolated high concentration near to Pettah and Thirumala
areas (Fig. 8 a&b). Both the images show isolated coldspots, which are well distributed in the study area.
Thus, the spatial pattern of accidents analysed in the present study enables the analyst to quickly and
aesthetically locate statistically satisfactory accident hotspots in the Thiruvananthapuram city corporation
area.
