Answer for Average traffic speeds

Answered By: 
The Mayor

Over the last three years the per-period range of London Traffic Speeds (measured in the 12 hours 7am to 7pm) has been between 17.37 and 20.02 mph. Average traffic speed varies by season, and the observation in period 2 last financial year at 17.40 mph was the second slowest average speed seen in three years.

The increase to 17.91 hours in period 2 this year is therefore within the low end of a range we have observed over the last three years.
