To ask the Secretary of State for Transport if he will make a statement on the relative changes in the cost of travel by rail, bus and car over the last 20 years; and what estimate he has made of the future changes under the 10 year plan. 
Real changes in the cost of different transport modes between 1974 and 1999 was shown in Graph 3c on page 22 of "Transport 2010: The Ten Year Plan" available in the Libraries of the House.The Department's latest forecasts for 2010 use a set of assumptions about the costs of travel in 2010, including future oil prices, fuel efficiency, and rail and bus fares. These assumptions are set out in "Modelling and Forecasting using the National Transport Model" (paragraphs 14 and 15). This document is available at www.transtat.dft.gov.uk/roadtraf/modelling/index.htm. These assumptions will be reviewed and updated as necessary as part of the review of the 10 Year Plan.
