Understanding the numbers
Traffic varies sharply by road type
The typical major-road point in West Sussex carries 16,386 motor vehicles on an average day, compared with 1,756 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.
