Question to the Department for Transport:

To ask the Secretary of State for Transport, if he will estimate how many vehicles per day using all or part of the M25 between junctions 3 and 29 in an anticlockwise direction joined the M25/A282 (a) before junction 2, (b) at junction 2, (c) at junction 1b, (d) at junction 1a and (e) at junction 30; and in each such case how many such vehicles left the M25/A282 (i) at junction 2, (ii) at junction 1a, (iii) at junction 31, (iv) at junction 30 and (v) after junction 30.

This information is not held.

The Department produces estimates of the number of vehicles per day using the main carriageway between motorway junctions (but not when they join and leave), available at the following link:
