Abstract
The Japan Coast Guard (JCG) provides the tidal current information at Kurushima Kaikyo Strait for vessels which are passing the Strait according to the Maritime Traffic Safety Law. In March 2012, we unified the information provision methods to the Electric Sign. We have 6 Electric Signal Boards at 4 Signal Stations and we installed 4 LED Signal Boards at 2 Signal Stations. The result of visibility survey of the signal boards using LED Units shows good condition to provide the tidal current information for vessels at Kurushima Kaikyo Strait area. usually use
