Abstract
The influence of darkness on the rate of traffic accidents was studied for several straits where the diurnal changes in the traffic volumes were well known and the number of accidents in five years were so large that the number of accidents in each section of hours was more than 10. The specific rates of collisions or strandings, showed a tendency common to all areas. Since Japanese water spreads mostly from 30 degrees N 40 degrees N, we may regard the time zone from 1800 to 0400 (dark) and 0800 to 1600 (bright). The specific rate obtained at dark time was about 4 times larger than that at bright time. The influence of fog was also studied using the result of survey on the frequency distribution of visibility, which gave the frequencies of visibility less than 1 km were about 1% in most of Japanese waters and those less than 200m were 0.1%. The analysis gave the results that both specific collision rate, specific stranding rate and the rate per length of fog time, are approximately inversely proportional to the visual range.
