In this report, we conduct a questionnaire survey in which we try to find the problems that ship's crews have regarding the speed restrictions along the Bisan Seto East Channel in Seto Inland Sea and whether the speed restrictions are necessary or not. We also conduct prototype simulation within the speed-restricted area of the Bisan Seto East Channel. The survey leads the following findings. (1) It becomes clear that the speed restrictions generate dangerous traffic congestion at the channel and more than 70% of the ship's crews require the improvement. (2) We newly propose a prototype simulation using the Collision Judgement with Fuzzy Inference. (3) This simulation shows that the values of the accumulations of Collision Judgment per day by the Collision Judgement with Fuzzy Inference do not increase when all the ships in the restricted area increase the speed by several knots. Meanwhile, when only one ship increase the speed, the accumulations of Collision Judgement the both crews that picks up the speed and of surrounding ships feel would increase. This shows a contrastive result to the case where all the ships increase the speed.
