Statistics on travel time measures for the Strategic Road Network (motorways and ‘A’ roads managed by Highways England) and for locally managed ‘A’ roads in England. For each, there is a measure of speed and delay, with an additional measure of reliability for the Strategic Road Network.
All statistical tables on congestion are updated on a quarterly basis. For local ‘A’ road statistics, we provide statistics by region and local highway authority which are updated on an annual basis (in February).
Following user feedback, from February 2018, we no longer intend to publish quarterly travel time statistical reports. Instead, we will publish an annual report (in February), although we will continue to update the supporting tables on a quarterly basis.
