asked the Secretary of State for Transport by what percentage he expects roll-on/roll-off traffic through the Kent ports to have increased by the end of the century.

Traffic forecasts are not available in the form requested. However, the National Ports Council forecasts that roll-on/roll-off traffic through South-East ports—that is, ports between London and Plymouth—will increase by about 90 per cent. by 1990. A large proportion of this growth can be expected to go through the Kent ports.
