To ask the Secretary of State for Transport how much was spent on the analysis by consultants of the impact of tolls on the traffic flow at the Dartford River Crossing; what assumptions were used in the analysis; and if he will make a statement. (117724)

Two reports have considered the implications of tolls on safety and traffic levels. In 2001 Brown and Root Consulting prepared a report on the “Short Term Study of Extension of Dartford Tolls”. In 2004 Jacobs Babtie produced a report on “Getting the Most out of the Dartford Crossing”. Both reports are available in the House Library and on the DfT website. Information about the costs of the studies is not available.
