A way to assess subjectively the risk of collisions between ships was developed to design new traffic routes and evaluate the change of marine traffic environment. Authors analyzed factors concerned with the risk assessment on ships collisions, using radar simulator and ship handling simulator. The results of pre-experiment indicated that two parameters, distance between ships and changing rate of relative bearing to target ship were useful to assess risk of ships collisions, rather than other parameters such as TCPA and DCPA. Regressive formulas to assess risk categories (danger area, caution area, safety area) were drived from total about 30,000 data points of simulator experiment. This experiment was carried out on pilots, captain and officers, by using mainly radar simulator with asking subjective categories to assess the risk collisions on traffic situations at every one minute. As a practical application, the assessment of risk categories, in case of crossing Akashi Strait, was carried out using above the regressive formulas, and we got reasonable results.
