§ Mr. Flynn
To ask the Secretary of State for Wales what changes have been made over the past 10 years in the predictions of traffic flows in the years 2000 to 2010 on the M4 between Tredegar Park interchange and the Coldra. 
§ Mr. Hain
Traffic predictions made in 1988 were based on the National Road Traffic Forecasts (NRTF) (Great Britain) 1984. From 1989 to 1997 they were based on the 1989 version of NRTF. Predictions from 1997 are based on the 1997 NRTF.
