Vehicle miles recorded
The Department for Transport record motor vehicle traffic (vehicle miles) by local authority in Great Britain on an annual basis. The time series goes back to 1993.
The number of vehicle miles travelled in the NELEP area and nationally both reached a peak in 2007. The financial crisis reversed the upward trend and it was 2010 before traffic started to increase.
By 2017 the national (GB) figure was 327 billion vehicle miles, 13 billion up on the 2007 figure; a 4.2% rise. In the NELEP area, the number of vehicle miles travelled in 2017 was 8.9 billion, 188 million above the 2007 peak; a 2.2% rise. The graph shows indexed trends for the NELEP area and England, indexed to 2007.
