The Akashi-kaikyo Bridge completed in 1998 and the Shimanami Expressway completed in 1999 followed the Ohnaruto Bridge and the Seto-ohasi Bridge that were built in 1985 and 1988. These changes in transportation networks have had strong effects on the truck transportation and the ferry lines between the Honshu and the Shikoku regions. A rise in the toll of these bridges by about 25% from April 2003 had been scheduled. On the other hand, the committee, which was established to discuss the problem of the public corporations for expressways and Honshu-Shikoku bridges, proposed in December 2002 that the toll of these bridges should be lowered by about 50%. The purpose of this study is to analyze influence of the rise, and the reduction, in the toll of Honshu-Shikoku bridges on trucks' use of the ferry lines and these bridges. We also try to find out the truck operators' requests to ferry companies. In this study, we make use of the result of the questionnaire survey which we carried out to the truck operators in December 2002. It is founded through this study that the truck operators have strong preference for ferry boats but over 20% to 50% of the trucks using ferry boats may change to the routes using the bridges if the toll of the bridges is reduced by more than 30%. We can also see the truck operators' requests to the ferry companies such as cuts in toll prices and increases in the frequency of ferries.
