TRAFFIC SAFETY COMMISSION
COMMISSION REPORT OF: July 7, 1986
LOCATION: 6200 Yarrow Drive
INITIATED BY: Ralph M. David,
Drive, Carlsbad, CA
PROBLEM AS STATED BY REQUE~TOR:
Dyna Industries,
92008
ITEM NO._L
6200 Yarrow
A crosswalk needs to be installed at 6200 Yarrow Drive and a
speed limit sign needs to be posted on Yarrow Drive between
Palomar Airport Road and Camino Vida Roble.
DATA:
Dyha Industries has their main building at 6200 Yarrow Drive
and warehouse across the street at 6221 Yarrow Drive.
Employees of Dyna Industries walk between the two buildings,
crossing Yarrow Drive in the process.
On June 5, 1986 a traffic study was performed. Traffic
volumes and pedestrian activity were observed to be low with
many long gaps available for pedestrians. Yarrow Drive is
approximately one-half mile long and has a curb to curb width
of 52 feet. NCTD sends two (2) buses an hour al9ng this
route. A traffic count made in August, 1984 showed an A.D.T.
of 3,400 on Yarrow Drive. In the past two (2) years, there
have been four (4) accidents along Yarrow Drive.
Crosswalks define and concentrate pedestrian walking areas
within an intersection or at other points within the roadway.
Their purpose is to alert the motorists of the possible
presence of pedestrians crossing the street. At the present
time, traffic engineering research is divided as to whether
crosswalks accomplish this purpose and make the motorists
more cautious .or if the crosswalk gives the pedestrian a
false sense of security because they expect the drivers to be
more aware of their presence.

ITEM N0._1_
There are no accepted warrants for painting crosswalks, but
they should be based upon:
1. Pedestrian volume crossing the street;
2. Vehicular volume, speed and turning movements;
3. Accident frequency at intersections; and
4. Width and shape of inter~ections.
Based upon the above findings and criteria, a crosswalk at
th1s location cannot be recommended.
A speed survey was taken that found the critical speed to be
46 M.P.H. (see attached). This indicates 85% of the drivers
perceive this to be a reasonable and prudent speed. Posting
a lower speed will not cause the drivers to slow down. None
of the accidents within the last two (2) years were
associated with excessive speed.
Yarrow Drive is a short industrial street within a 62-foot
right-of-way. It has a maximum grade of 4.201, from Palomar
Airport Road down to Camino Vida Roble. Sight distance is
good. Speed limit signs, when posted, are placed at one-half
mile intervals in the City of Carlsbad. One side street is
located at approximately the middle of Yarrow Drive.
CONCLUSION:
Based upoon the existing roadway conditions, low traffic
volumes, low accident history and the results of the speed
survey, a speed limit sign cannot be recommended.
RECOMMENDATION:
Staff recommends denial of the request for a crosswalk and
speed limit sign. Staff will continue to monitor this area
in the future to determine if either is necessary.
NECESSARY COUNCIL ACTION:
None required if the request is denied. An
resolution will be required for Council action
limit sign is recommended.
