Dear Mr. Holzmiller:
This letter is an addendum to our report of December 29, 1980, relative to
the potential traffic impacts of the proposed Sun Faire Festival at the Carlsbad
Raceway. The previous report was contained in a letter addressed to Mr. Peter
Meisen.
Linda Vista Road/Encinitas Road intersection which also serves as the entrance
to the Carlsbad Raceway.
This addendum addresses traffic operations at the Palomar Airport Road/
EXISTTNG CONI) IT IONS
Palomar Airport Road is a two-lane facility with a separate left turn pocket
provided for eastbound traffic ilt Linda Vista/Encinitas. ThlH left turn pockcat
has a storage of approximately 50 feet and a width of approximately 10 feet.
Palomar Airport Road forms a "Y" intersection with Linda Vista/Encinitas Roads
at this point. Westbound traffic on Encinitas is controlled by a YIELD sign
at its entrance to Palomar Airport Road. A short section of Linda Vista
Road is utilized for all other movements between Palomar Airport Road and
Encinitas Road. These are no advanced warning signs on Palomar Airport Road
indicating the Linda Vista/Encinitas intersection.
The entrance to the Carlsbad Raceway is an extension of Linda Vista Road. This
results in all traffic entering or leaving the Raceway having to cross the
westbound traffic on Encinitas Road. A STOP sign does exist for vehicles
existing from the Raceway at Encinitas Road.

ANALYSIS
There are two potential problems at this intersection that could develop with
the Sun Faire Festival operation. The first is the increased activity at the
Palomar Road/Linda Vista intersection. As is indicated by the length of the
existing left turn pocket, current volumes are relatively light and trafiis on
Palomar Alrport Hoad may noL lx aware of the Iritcrscction. Slght ciistancc for
vehicles on Palomar Airport Road approaching the intersection is somewhat
restricted due to horizontal and vertical alignment of this road.
A similar potential problem exists for westbound traffic on Encinitas Road.
there is normally little traffic flow in or out of the Raceway, drivers are not
anticipating any conflicts and are watching traffic on Palomar Airport Road.
Since
In our previous report, we recommended police traffic control at this intersection
during peak periods. Due to the conditions described above, it is also recommended
that advanced intersection warning signs be installed on both approaches on Palomar
Airport Road and the westbound approach on Encinitas Road. These signs should
be installed approximately 750 feet in advance of the intersection.
A second potential problem is related to the length of the left turn pocket for
eastbound traffic on Palomar Airport Road.
this pocket to provide a 200 foot storage area. This would reduce the changes
of rear-end collisions and the blocking of the eastbound through lanc. This
change in striping could be accomplished without additional pavement.
It would be desirable to extend
SUMMARY
This letter summarizes an additional review of the potential impacts of the Sun
Faire Festival at the Palomar Airport Road/Linda Vista Road/Encinitas Road
intersection. Potential problems were identified due to the increased use of the
intersection which would result from the festival and the restricted sight distances.
It has been recommended that advanced intersection warning signs be installed
on all approaches LO the intersection. In addition, it is recommended that the
eastbound left turn lane on Palomar Airport Road be lengthened to provide a
200-foot storage area.
