How this was measured, and what it cannot tell you
Vegagerðin counts vehicles every ten minutes at a counter 2.6 km away, on Dettifossvegur. This page averages 242 days of those counts by hour of day.
What it cannot tell you: how many people are there. A coach is one vehicle and fifty visitors, so a road that is quiet by traffic can still have a full viewing platform. The counter is on the road, not at the site, so it sees everyone driving past — including people going somewhere else entirely. And it describes a normal summer day, not tomorrow: weather and a cruise-ship arrival both beat any average.
