ABSTRACT
On March 19, 1996, City Council approved all-way stop controls at this location and
requested a Traffic Safety Committee review of advance stop control notification. Stop
and stop ahead signs and legends were installed on April 4, 1996. Temporary
supplemental signs were also installed to emphasize the changes. On April 9, 1996, the
Traffic Safety Committee concluded that sign visibility, with a 48-inch stop sign, and
advance notification are adequate, flashing lights should not be installed at this
time, and that the intersection should be monitored for accidents.

Review of All Way Stop Controls at the Intersection of
Metate Lane and Carriage Road
On March 19, 1996, City Council approved installation of all-way stop controls
at Metate Lane and Carriage Road and requested the Traffic Safety Committee
review advance notification for the stop controls to ensure visibility and
safety.
FINDINGS
Stop and stop ahead signs with applicable legends were installed on Metate on
April 4, 1996. Temporary supplemental signs were installed with the new stop
controls to emphasize the changes. On April 9 the Traffic Safety Committee
reviewed the intersection to ensure proper sign visibility and to identify
other actions which could be taken to inform drivers of possible stopped cars
at the bottom of the hill. In the review, it was recommended that the oversize
36-inch stop sign be replaced with a 48-inch sign. It was noted that traffic
appears to be adjusting safely to the new conditions.
The TSC concluded that visibility of all signs is adequate for both daytime
and nighttime conditions. The hill easterly of the intersection limits
visibility of stopped cars in the westbound direction. Except for
reconstruction to reduce the slope of the hill, no other improvements could be
provided to improve visibility of cars stopped at the intersection. The TSC
recommended that the intersection be monitored to ensure that a pattern of
sight visibility-related accidents does not develop.
Installation of flashing lights was considered. When used at stop locations,
they are generally installed on the stop sign poles. An example of flashers
used at stop signs can be seen at the intersection of Martincoit Road and
Rostrata Road. Flashers are not usually used on residential streets as they

can have adverse effects (constant flashing, particularly at night) on nearby
residences. Because there are residences on two corners of Metate and
Carriage, flashers were not installed at this time. If evidence develops that
additional notification is needed, red flashing lights can be considered for
installation at either the stop ahead sign or at the stop sign. They are not
recommended at this time because of the negative effects previously mentioned.
Supplemental signs such as "prepare to stop" could be installed, if needed.
This intersection will be added to the all way stop locations which are
reviewed annually for safety by the TSC.
