How this was measured, and what it cannot tell you
Vegagerðin counts vehicles every ten minutes at Kvísker, 6.6 km away, on the Ring Road at Kvísker, the approach shared with Jökulsárlón. This page averages 142 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.
