TRAFFIC SAFETY COMMISSION
COMMISSION REPORT OF: July 6, 1987 ITEM NO. 6C
LOCATION: Alga Road-El Fuerte Street to Melrose Drive
INITIATED BY: Traffic Engineering Division
BACKGROUND:
DATA:
Widening of Alga between El Fuerte street and Melrose
Drive 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.
Between El Fuerte Street and Melrose Drive, Alga Road is
a four lane, divided road approximately 2900 feet in
length. Xana Way intersects Alga Road 1100 feet easterly
of El Fuerte Street to create a four-leg intersection.
At this time the southerly leg of Xana Way is open only
to construction traffic. Alga Road has been constructed
with an 8.00% grade between Xana Way and Melrose Drive.
The A.D.T. on Alga Road is approximately 5,000 vehicles.
At the intersection of Melrose Drive, traffic on Alga Road
must negotiate a 90° turn to proceed southerly on
Melrose Drive (Exhibit 1). The northerly and easterly
legs of the Alga/Melrose intersection have not been
constructed at this time. An advance warning Turn Sign
(W3) with a 15 mile per hour advisory speed plate (W6)
has been installed prior to the turn from Alga Road to
Melrose Drive.
A speed survey was conducted to determine the prevailing
speed (85th percentile) on Alga Road (Exhibit 2). No
accident history is available due to the road just being
completed and opened to traffic.
