The Director of Public Works or his/her designee
shall place and maintain traffic-control signs, signals and devices
when and as required under the traffic ordinances of this City to
make effective the provisions of said ordinances, and may place and
maintain such additional traffic-control devices as he/she may deem
necessary to regulate traffic under the traffic ordinances of this
City or under state law or to guide or warn traffic.
All signs, signals and devices required hereunder
for a particular purpose shall so far as practicable be uniform as
to type and location throughout the City. All traffic-control devices
so erected and not inconsistent with the provisions of state law or
this chapter shall be official traffic-control devices.
Whenever traffic is controlled by traffic-control
signals exhibiting different colored lights successively one at a
time, or with arrows, the following colors only shall be used and
said terms and lights shall indicate and apply to drivers of vehicles
and pedestrians as follows:
A. Green alone:
(1) Vehicular traffic facing the signal may proceed straight
through or turn right or left, unless a sign at such place prohibits
either such turn. But vehicular traffic, including vehicles turning
right or left, shall yield the right-of-way to other vehicles and
to pedestrians lawfully within the intersection or an adjacent crosswalk
at the time such signal is exhibited.
(2) Pedestrians facing the signal may proceed across the
roadway within any marked or unmarked crosswalk only in the direction
indicated by the signal for the movement of traffic.
B. Steady yellow alone:
(1) Vehicular traffic facing the signal is thereby warned
that the red or "STOP" signal will be exhibited immediately thereafter
and such vehicular traffic shall not enter or be crossing the intersection
when the red or "STOP" signal is exhibited.
(2) No pedestrian facing such signal shall enter the roadway
unless authorized so to do by a pedestrian "WALK" signal.
C. Steady red alone or "STOP":
(1) Vehicular traffic facing the signal shall stop before
entering the crosswalk on the near side of the intersection or, if
not, then before entering the intersection and shall remain standing
until authorized by the pedestrian "WALK" signal, and shall not prior
to reaching such intersection make any turn over or through private
property in order to avoid such signal; provided, however, that a
right-hand turn shall be permitted after vehicular traffic reaches
a complete stop, at the intersection when safety would permit such
a turn and no sign forbids it.
(2) No pedestrian facing such signal shall enter the roadway
until authorized to do so by a pedestrian "WALK" signal.
D. Steady red with green arrow:
(1) Vehicular traffic facing such signal may cautiously
enter the intersection only to make the movement indicated by such
arrow but shall yield the right-of-way to pedestrians lawfully within
a crosswalk and to other traffic lawfully using the intersection.
(2) No pedestrian facing such signal shall enter the roadway
unless authorized to do so by a pedestrian "WALK" signal.
E. Signal at a place other than an intersection. In the
event an official traffic-control signal is erected and maintained
at a place other than an intersection, the provisions of this section
shall be applicable except to those provisions which by their nature
can have no application. Any stop required shall be made at a sign
or marking on the pavement indicating where the stop shall be made,
but in the absence of any such sign or marking the stop shall be made
at the signal.
Whenever special pedestrian-control signals
exhibiting the words "WALK" or "WAIT" or "DON'T WALK" are in place
such signals shall indicate as follows:
A. WALK: Pedestrians facing such signal may proceed across
the roadway in the direction of the signal and shall be given the
right-of-way by drivers of all vehicles.
B. WAIT or DON'T WALK: No pedestrian shall start to cross
the roadway in the direction of such signal, but any pedestrian who
has partially completed crossing on the walk signal shall proceed
to a sidewalk or safety zone while the "WAIT" or "DON'T WALK" signal
is showing.
The Director of Public Works or his/her designee
is hereby authorized to:
A. Designate and maintain, by appropriate devices, marks
or lines upon the surface of the roadway, crosswalks at intersections
where in his/her opinion there is particular danger to pedestrians
crossing the roadway, and at such other places as he/she may deem
necessary.
B. Establish safety zones of such kind and character
and at such places as he/she may deem necessary for the protection
of pedestrians.
The Director of Public Works or his/her designee
is hereby authorized to place, erect and maintain divisional, channelizing
and rotary islands upon the surface of the roadway at such places
as he/she may deem necessary to increase the flow of traffic in a
more orderly and safe manner.
The Director of Public Works or his/her designee
shall have authority to declare any street or part thereof closed
for the purpose of moving of buildings, demolition of buildings, rebuilding
of highways, sewer construction, water construction, gas construction,
telephone and electrical duct construction because of the impossibilities
or hazardous conditions of regular travel over the roadway at the
construction site and shall detour traffic to another street as he/she
deems necessary.
