Key points

We have implemented some methodology changes this month to improve the quality of these statistics. As expected, the changes have resulted in a shift in the estimated level of journey time reliability and revisions to the historical national series. Further information on the methodology changes is provided in Section 2 of this release.

  • In the year ending January 2013, provisional data show that 78% of journeys on the Highways Agency managed network were ‘on time’. This is 0.6 percentage points lower than the previous year, ending December 2012.

  • Provisional data show that 73.5% of journeys on the Highways Agency network during January 2013 were ‘on time’, down 7.3 percentage points from January 2012.
