In year ending to June 2015 average speeds on local ‘A’ roads in England during the weekday morning peak were 23.8 mph. This is a 0.6% decrease on the year ending March 2015.
For individual months average speeds on local ‘A’ roads in England were slower across April, May and June 2015, with decreases of 3.1%, 1.2% and 2.3% respectively, compared to the same months in 2014.
Over the longer term, a combination of increases in traffic on the ‘A’ road network and intermittent periods of high rainfall levels are likely to have contributed to the fall in speeds observed between March 2012 and June 2015.
