A-road congestion

Average vehicle speeds on A-roads in England have increased, to 24.9mph

Getting stuck in traffic on A-roads in London is common, but how does the average speed of vehicles in England's capital compare to other parts of the country?

According to the Department for Transport (DfT), local authority-managed A-roads carry around half of the total traffic in England, so it is vital congestion is kept to a minimum. Last week, the DFT released provisional average speed data for these roads for the first quarter of 2012.

Inner London has predictably slow roads, but it's surprising to see 17 other areas from around the country with average speeds of 20mph or below.
