To ask the Secretary of State for Transport what assessment he has made of the merits of funding new trunk roads in the private sector through road tolls; and if he will make a statement. [101639]

There has been no general assessment of funding new trunk roads in the private sector through road tolls.

To ask the Secretary of State for Transport what his latest estimate is of the total external social costs in pence per average vehicle mile for road travel in the United Kingdom accounted for by (a) congestion costs, (b) accident costs, (c) air pollution costs, (d) noise pollution costs and (e) climate change costs; and if he will make a statement. [101526]

A study commissioned by my Department from the Institute for Transport Studies¹ at the University of Leeds made the following estimates of the marginal external social cost of road use per vehicle kilometre in Great Britain:

a) Congestion costs: 9.71 to 11.16 pence

b) Accident costs: 0.82 to 1.40 pence

c) Air pollution costs: 0.34 to 1.70 pence

d) Noise pollution costs: 0.02 to 0.78 pence

e) Climate change costs: 0.15 to 0.62 pence

To ask the Secretary of State for Transport what his estimate is of the total growth in vehicle miles travelled on United Kingdom roads in each year from 1980–81 to 2002–03; and if he will make a statement. [101527]

The year on year growth rates for vehicle miles travelled from 1980–81 to 2002–03 are detailed in the table.
