Understanding the numbers

Traffic varies sharply by road type

The typical major-road point in Buckinghamshire carries 15,918 motor vehicles on an average day, compared with 1,589 at sampled minor-road locations.

Minor-road coverage is selective, so quieter residential streets may not have their own count point. Use the map to see the exact measured or estimated location rather than treating this as a street-by-street census.
