Community Plan Traffic Estimates
The Community Plan Traffic Element shows the
average daily traffic trips (ADT) at build out for the community.
This Community plan was approved/adopted in 1993.
Transportation Element of Rancho Peñasquitos Community Plan, revised
in 1993.
SANDAG Report Year 2004
Comparison
The ADTs for Carmel Mtn. Rd. may be
inaccurrate - traffic has increased dramatically since Hwy. 56
opened. If the numbers show an increase along Carmel Mtn. Rd. from Peñasquitos Blvd. to Peñasquitos Drive
since 2002 - where is the increase from Peñasquitos Drive to
the interstate? ADTs in a nutshell...
-
Carmel Mtn .Rd going north from Rancho
Peñasquitos Blvd. to Peñasquitos Dr., the ADTs were 18.5 thousand in
2004, (increased from 14.4 thousand in 2002).
-
Carmel Mtn. Rd. between Peñasquitos Dr. &
I-15 saw 24.4 thousand ADTs going north from Peñasquitos Dr.
intersection to I-15 in 2004. Note: ADTs
haven't changed since 2000.
-
Peñasquitos Dr. going north between Carmel Mtn Rd. &
Almazon St. saw 15.3 thousand ADTs going up hill into the community
in 2004 - down one thousand since previous counts. There aren't
fewer homes up here, so is the count accurate?
-
If counts were to be done today, the ADTs
would be higher yet due to the delays at Hwy. 56 & I-15 interchange
ramps offering limited access to either highway in any direction.
Drivers exit Hwy. 56 at Black Mtn. Rd. & Rancho Peñasquitos Blvd. and
use Carmel Mtn. Rd. north to access I-15 or cross into Carmel Mtn.
Ranch or to access Rancho Bernardo.
