Parliamentary constituencies are not held centrally.</p><p> </p><p> </p><p> </p><p>We
do however hold data at the local authority level. Road congestion is measured in
the Department by morning peak speeds, defined as 7am to 10am. In 2013, the average
weekday morning peak speeds, on locally managed ‘A' roads in Blackburn with Darwen
(local authority) and Lancashire County, both of which partly contain Rossendale and
Darwen constituency, were estimated to be 19.3 and 25.3 miles per hour respectively.
The equivalent figure for the whole of England in 2013 was 24.7 miles per hour.</p><p>
</p><p> </p><p> </p><p>Equivalent figures for earlier years back to 2007, and all
other local highway authorities in England, can be found on the Department for Transport's
website at:</p><p> </p><p><a href="https://www.gov.uk/government/uploads/system/uploads/attachment_data/file/279125/cgn0206.xls"
