Below are several charts and maps
tabulating Annual Average Daily Traffic (AADT) counts on San Antonio's freeways
for 2008. The comments,
rankings and calculations are my own analysis based on raw data
from TxDOT.
The stats below are
area-wide. To see traffic counts for just a specific corridor, see
that freeway's individual page elsewhere on this site.
Summary
Overall traffic was down
again in 2008, mirroring the trends across the nation due to the economic
downturn. Bexar County VMT was down about 4% over 2007.
Still, some locations of the city showed substantial traffic growth
including SH 151, NE Loop 1604, the eastern end of Wurzbach Parkway,
I-35 North near BAMC and I-35 South just inside Loop 410. Notable
increases were also seen on I-10 West inside Loop 410, likely due to
construction being completed there, and Loop 410 between I-10 and US
281. A surprise increase was seen on General Hudnell near US 90.
On location dropped below
200,000 vehicles per day (VPD) this year (I-35 at Thousand Oaks), but
two more moved above that mark, both on I-35 (McCullough and Rittiman).
The city's busiest location continues to be I-10 at Callaghan,
shooting-up over 10% this year to 238,000 VPD, followed by I-10 at
DeZavala, which moved up from third to second busiest with 221,000 VPD.
I-35 at Thousand Oaks and at Walzem were just shy of the 200,000 mark
and will likely rejoin the club next year.
Over the past decade, the top
spots continue to be concentrated on NW Loop 1604, I-10 West, and SH
151. However, this year saw a shift in the fourth "cluster" of
increases from Loop 410 South up to NE Loop 1604. US 281 near Loop
1604 and I-35 South near Loop 410 round-out the top 20 growth locations
since 1998.
