Journey time reliability fell for 12 consecutive months from a March 2012 peak of 81.5%, but has been mostly stable since March 2013. The DfT says this stabilisation is probably due to a combination of improved weather conditions (particularly less rain) and increases in traffic on motorways and rural ‘A’ roads, relative to the previous 12 months
