An error has been identified in the congestion statistics published by the Department for Transport on 2 June 2011.

This was published under the 2010 to 2015 Conservative and Liberal Democrat coalition government

An error has been identified in the congestion statistics that were published by Department for Transport earlier today (2 June 2011). The error affects the A428 which was identified in the statistics release as a poor performing route.

Some of the data for sections of the A428 has now been found to be faulty; this contributed to the artificially low reliability figures for the A428 up to February 2011, which we do not believe reflect the actual journey times on the route. We are urgently reviewing our data checking procedures to establish why this error was not identified earlier and ensure this does not happen again.

However, because there was an error in one of the detailed routes all individual routes have been withdrawn for further checks. We will reinstate this data as soon as possible.

The revised publication is available.
