内容記述 | The aim was to propose techniques for analysis of spatiotemporal patterns of vehicle collisions with an endangered species. We examined Iriomote cat-vehicle collisions from 1978-2008 (n=46) along only a 50-km trunk road in the Iriomote island of Japan. The collisions obeyed a nonhomoge-neous Poisson process with mean λ(t) that increased with time t. Hence, the collisions turned out to be increasing steadily. To test for spatial distribution, the road was divided into 500 segments. We assumed a null hypothesis that each collision occurred with the same probability on each of the seg-ments. We generated 1000 samples, each of which consisted of 46 randomly selected segments, and counted clusters of various sizes. We defi ned a cluster as collisions 4 (size 4) within 1 km. The results were 1.544/sample for size 4, 0.349/sample for size 5, 0.054/sample for size 6, and 0.008/sam-ple for size 7. The real distribution had 1 cluster of size 4, 2 clusters of size 5 and 2 clusters of size 7 (P<0.001). In the almost all of these clusters, it have already paid for many eff ort to prevent cat-vehicle collision such as underpasses, elevated segments of the road and zebra zone, our fi ndings suggest that it is reasonable statistically. Because the situation around the cat-vehicle collisions, such as road structure, traffic volume and habitat condition of the cat along the road, has been changed, we think also that it is necessary to examine further analysis using additional data to sug-gest the measurement against collision eff ectively. | |||||
