Analysis of travel times on the strategic road network, England: 2014

An analysis of travel times on the strategic road network, for the 2014 calendar year (January to December).



Travel times on the strategic road network have been analysed using the following 3 statistical measures:

  • average speed
  • average delay
  • reliability (measured by the planning time index)

The analysis contains both monthly and annual data for each of the measures.

This analysis is intended to introduce these 3 new measures to users of the strategic road network statistics, with an intention of producing statistics of a similar nature to the ones presented in the analysis later in 2015.
