Motorway and ‘A’ road figures for reliability of journeys between July to September 2013.
This release represents finalised data for July and August 2013 and includes provisional data for September 2013. The statistics include reliability of journeys on motorways and ‘A’ roads managed by the Highways Agency, known as the strategic road network
77.4% of journeys on the Highways Agency’s network were ‘on time’ in the year ending September 2013, 0.3 percentage points higher than the year ending June 2013.
Reliability was at its peak in the year ending March 2012 with 81.5% of journeys ‘on time’. Reliability then fell for 12 consecutive months before stabilising from March 2013 onwards.
The recent stabilisation of reliability levels may relate to a combination of improved weather conditions, particularly less rain, and increases in traffic on motorways and rural ‘A’ roads, relative to the previous year.
