Hyder Consulting is reviewing the toll system on the Forth Road Bridge in Scotland, UK. Payments are cash-only now but traffic has boomed to 23 million vehicles per year up from 13.6 million since the existing system was specified in 1991. "We will be looking at whether customers might be offered a greater choice of payment methods, such as contactless smart cards and electronic toll collection," says Jack Opiola, Hyder Consulting's director for intelligent transport systems.
