TRAFFIC SAFETY COMMISSION
COMMISSION REPORT OF: July 6, 1987 ITEM NO.~6=D __
LOCATION: Melrose Drive-Alga Road to Rancho Santa Fe Road
INITIATED BY: Traffic Engineering Division
BACKGROUND:
DATA:
Widening of Melrose Drive between Alga Road and Rancho
Santa Fe Road has recently been completed. A prima
facie speed limit must be established on this portion
of the road in order that posted speed limit signs can be
installed.
Melrose has been constructed as a six lane, divided road
approximately 1/2 mile in length between Alga Road and
Rancho Santa Fe Road. It has been constructed with a
maximum 8.00% grade. The A.D.T. is approximately 5,000
vehicles. Corintia Drive intersects Melrose Drive
approximately 400 feet northerly of Rancho Santa Fe Road
to create a T-intersection.
Traffic approaching the Melrose/Alga intersection must
negotiate a 90 • turn to proceed westerly on Alga Road
(Exhibit 1). At this time, the northerly and easterly legs
of the intersection have not been constructed. An advance
warning Turn Sign (W3) with a 15 mile per hour advisory
speed plate (W6) has been installed in advance of the
turn from Melrose Drive to Alga Road.
A speed survey was conducted to determine the prevailing
speed (85th percentile) on Melrose Drive (Exhibit 2). No
accident history is available due to the road just being
completed and opened to traffic. Based upon the critical
speed and roadway conditions, the recommended speed
limit is 45 miles per hour.
RECOMMENDATION:
The Traffic Safety Coordinating Committee recommends
that a 45 mile per hour prima facie speed limit be
established on Melrose Drive between Alga and Rancho
Santa Fe Road.
