After recently returning from a family vacation to Corolla, NC on the Outer Banks in which we encountered significant traffic just getting to our destination (especially a family member's hour-later departure time resulted in a 3 hour difference in arrival time), it got me wondering about whether questions about the "best" time to arrive to limit traffic delays would be on topic.
I can see that travel times as a whole is much too broad and virtually unanswerable since there are too many variables to account for, but on the other hand, experienced travelers would know the ideal times to arrive at a given location to limit the delays due to traffic. Since the summer traffic on a typical arrival day (Saturday) would be reasonably predictable, it stands to reasons someone could provide advice on when to plan to arrive on the island to avoid significant delays. Similarly, I could imagine other vacation destinations around the globe have similar access challenges and would require advice on when to arrive.
For those who don't know, the Outer Banks of North Carolina are a barrier island with essentially 1 4-lane (2 each direction) bridge onto the island and a single 2 lane road north and south to connect the various communities to the bridge. From the time we hit traffic, it took us close to 3 hours to reach our destination, and a family member who was about an hour behind us arrived 4 hours after we did.
