When I do the arithmetic, it seems like they are saying July traffic is about 9.6% higher, not 9.6% lower than a typical month.
You're right. Usually a seasonal adjustment factor is what you multiply a raw count by to get the AADT, but it appears NYSDOT does the opposite. Summer traffic is actually higher.
It also looks like they are just ignoring the 12 hours of Friday data. Why not just pick up the counter 12 hours later and get a full week?
Probably because they were moving the counter elsewhere and had to get it ready to count Saturday.
You say a blockage won't last 6 1/2 days? Why not? if one lane is consistantly blocked by at least one double parked truck every day, making it virtually unusable, how would you know without manual observations?
If the lane is always virtually unusable, then it's fair to say it's a permanent condition.
Also, why does it say SB in the upper left corner when Bedford is Northbound not SB?
