A. REQUEST TO INSTALL 4 -WAY STOP SIGNS AT THE INTERSECTION OF 45
AVENUE AND 6 TH STREET OR 7 TH STREET
Mr Cory Mattson of 4500 Washington Street has requested 4 -way stop signs at the
intersection of 45 Avenue at either 6th Street or 7 th Street. Mr Mattson's concern and the
concern of his neighbors is the speed of traffic on 45 Avenue. There are no stop signs
which stop traffic on 45 Avenue between Jefferson Street and University Avenue
Service Drive. Mr Mattson's letter is included in your packet.
Traffic currently stops at each north -south street along 45 Avenue, except University
Avenue Service Drive. There have been 4 reported accidents over the last 3 years:
45 Avenue at University Avenue Service Drive (4/11/10),
45 Avenue at Washington Street (4/16/08),
45 Avenue between Washington and Jefferson Streets (12/22/10), and
45 Avenue at Jefferson Street (12/16/10).
Information from Police Captain Austin is attached in your packet.
The MUTCD guidelines for installing 4 -way stop signs are listed below and included in
your packet:
Multiway stop control can be useful as a safety measure at intersections if certain
traffic conditions exist. Safety concerns associated with multiway stops include
pedestrians, bicyclists, and all road users expecting other road users to stop. Multiway
stop control is used where the volume of traffic on the intersecting roads is approximately
equal.
A. Where traffic control signals are justified, the multi -way stop is an interim
measure that can be installed quickly to control traffic while arrangements are
being made for the installation of the traffic control signal.

B. A crash problem, as indicated by 5 or more reported crashes in a 12 -month
period that are susceptible to correction by a multi -way stop installation. Such
crashes include right- and left -turn collisions as well as right -angle collisions.
C. Minimum volumes:
1. The vehicular volume entering the intersection from the major
street approaches ( total of both approaches) averages at least 300
vehicles per hour for any 8 hours of an average day, and
2. The combined vehicular, pedestrian, and bicycle volume entering
the intersection from the minor street approaches (total of both
approaches) averages at least 200 units per hour for the same 8 hours,
with an average delay to minor- street vehicular traffic of at least 30
seconds per vehicle during the highest hour, but
3. If the 85 th - percentile approach speed of the major street traffic
exceeds 40 mph, the minimum vehicular volume warrants are 70
percent of the above values.
D. Where no single criterion is satisfied, but where Criteria B, C.1, and C.2
are all satisfied to 80 percent of the minimum values. Criterion C.3 is
excluded from this condition.
Other criteria that may be considered in an engineering study include:
A. The need to control left -turn conflicts;
B. The need to control vehicle /pedestrian conflicts near locations that
generate high pedestrian volumes;
C. Locations where a road user, after stopping, cannot see conflicting traffic
and is not able to reasonably safely negotiate the intersection unless
conflicting cross traffic is also required to stop; and
D. An intersection of two residential neighborhood collector (through) streets
of similar design and operating characteristics where multiway stop control
would improve traffic operational characteristics of the intersection.
The traffic and pedestrian volume, accident record and intersection configuration do not
meet the requirements for installing 4 -way stop signs.
The speed trailer has been used on 45 Avenue during the week. Captain Austin will
have results at the meeting on Monday night.
Based on the information available, it is staff s opinion the intersections do not meet the
MUTCD guidelines for installation of 4 way stop signs. As stated in the MUTCD in
Section 2B.5 STOP Sign Applications under Guidance, "STOP signs should not be used
for speed control." Stop signs are meant to assign right -of -way, not to control speed.
Studies have shown that traffic will only slow in the vicinity of the stop signs.
RECOMMENDED MOTION: Move to deny the request to install 4 -way stop signs at
the intersection of 45 Avenue and either 6 Street or 7 th Street.

PUBLIC HEARING FOR 50 AVENUE NE, EAST OF CENTRAL AVENUE
There are issues with safety and congestion at the 50 Avenue and Central Avenue intersection. Another
issue is additional traffic on Tyler Street generated by businesses on Central Avenue, such as Jimmy
John's and potentially ALDI.
A.
L
DESIGNATE "NO PARKING" ON 50 AVENUE NE FROM CENTRAL AVENUE TO THE
EAST PROPERTY LINES OF 4955 AND 5001 CENTRAL AVENUES.
Kathy Young stated the intersection at 50 Avenue and Central Avenue can be hazardous with lots
of conflicting movement. The public hearing was called to discuss the implementation of "No
Parking" on 50 Avenue from Central Avenue to the east property lines of Jimmy John's and
ALDI's. This will improve visibility and allow for the full width of the street to be used for traffic.
This recommendation came from staff, residents, and MnDOT. Residents present agreed.
Motioned by Doty, seconded by Olson to recommend the City Council designate "No Parking" on
50 Avenue from Central Avenue to the east property lines of Jimmy John's and ALDI's. Motion
passed unanimously.
DISCUSS ASSIGNING THE EXIT FOR THE FRONTAGE ROAD SOUTH OF 50' AVENUE
AS "RIGHT TURN ONLY."
Designating the frontage road south of 50 as "Right Turn Only" would eliminate potential
conflicts at the intersection as vehicles leaving the frontage road try to cross the eastbound lane of
Traffic Commission Minutes —April 4, 2010
Page 2
traffic to go west on 50 Avenue or north on Central Avenue. The drawback is that this will
increase traffic on Tyler Street as drivers make their way back to Central Avenue: 50 Avenue to
Tyler Street to 49 Avenue to Central Avenue.
Currently the street is 33 feet wide. A right turn lane would add 10 -12 feet to the current width.
The Public Hearing was called to discuss designating the frontage road as a right turn only, or to
not allow traffic to exit the frontage road but require them to use the south driveway. Two days of
traffic counts showed approximately 230 cars a day exit the frontage road over an eight hour
period; this amount would be higher over a 24 -hour period. Staff supports installation of a sign
directing northbound Central Avenue traffic to the south driveway entrance of the mall.
Proposals as items for discussion: 1. Leave the way it is. The problem is vehicles leaving and
trying to get across the street cause traffic problems. 2. Designate right turn only. The problem is
this sends cars into residential areas. 3. Do not allow vehicles to exit the frontage road but have
them come back to south driveway. The problem with this is if vehicles want to go southbound
they must cross three lanes of traffic and then make a U -turn at the light. There are potential
problems with each of these solutions.
Todd Hanson of 4918 Tyler Street stated that not allowing vehicles to exit the frontage road would
be good but it may hurt the businesses. Kathy said she spoke with the property manager of 4915
Central (mall) who stated that customers want an easy way in and an easy way out. Mr. Hanson
stated that a right turn only on the frontage road will cause 2,000 cars go by his house. He
suggested that we dead end Tyler Street.
Another resident stated there are lots of kids in the area and the drivers get frustrated with them.
She does not want the right turn only off the frontage road and the traffic it will generate on Tyler
Street. Mr. Hanson stated there is already too much traffic from Jimmy John's - -using Tyler as a
racetrack. He again suggested we dead end Tyler Street. Chairperson Goodman agreed we need to
block off somewhere on the 50th side but Kathy stated if we did that we would then be sending
traffic east all the way to Fillmore. Residents feel it is deadly on Tyler Street due to all the
children. Apparently they conglomerate in one yard on the corner. They feel someone is going to
be killed because of cars using Tyler as a cut through between 49` and 50 and driving fast.
Residents suggested speed bumps but did not know if they would be effective. Someone also
suggested a one -way towards 50P or a dead end at 50 similar to 7 th Street at 53 Avenue.
Goodman suggested a three lane road on 50 at Central with a left turn lane, through lane, and
right turn lane. However, there is not enough space for this as the road would only be about 40
feet wide. Because it is a MnDOT road we would need more footage for three lanes. Chairperson
Goodman suggested another street to make a right turn off the service road or build another way of
getting out of ALDI's - -some type of exit for a right turn only. However, ALDI's driveway is far
enough back from Central, it will actually be in the same location as the doughnut shop so it is
easy to exit. Traffic leaving ALDI's will increase the number of vehicles but will not generate
more traffic on Tyler Street. ALDI's has pledged to inform suppliers not to use Tyler Street for
deliveries. Mr. Hanson stated most of the speeding is from Jimmy John's delivery vehicles and
there has been no cooperation from the franchise. It is also busy for about one -half hour after
school gets out. Traffic has increased on 50 Avenue since Jimmy John's opened and they do

speed.
Goodman suggested a separate right turn lane with a yield sign at the intersection onto Central. This
would allow a continuous flow of traffic and eliminate a backup at the light. This would require staff
to check with MnDOT and it would involve more work depending on where the signal pole is located.
Another problem is that part of this area is private property—staff would need to contact ALDI's and
ALDI's is reluctant to give up parking spaces. MnDOT would also need to get involved to change the
traffic light patterns. It was noted that just changing traffic lights on the east -west side would help free
up the intersection because traffic will move. Kathy stated that MnDOT is looking at changing those
traffic lights in 2012 or 2013. Traffic on Tyler is directly related to rush hour and Jimmy John's.
ALDI's will not generate AM or PM peaks. Kathy stated staff will not support a right turn lane only
out of ALDI's. Due to time constraints of Sergeant Fischer, Kathy suggested we table this item until
later in the meeting. Motioned by Doty to table item 2 until later in meeting, seconded by Olson. All
ayes. Motion carried.
C. DISCUSS "NO THROUGH TRAFFIC" ON TYLER STREET, 49 AVENUE TO 50
AVENUE
Suggestions for limiting traffic on Tyler Street have been to sign Tyler Street for "No Thru Traffic" or
"No Delivery Service Vehicles ". Staff recommended a weight limit sign be installed consistent with
other signs in the City.
A standard sign would not apply to delivery cars. Sergeant Fischer stated signs can only be enforced
when an officer is present and this would not be a high priority. Also, officers need to know exactly
what the sign means and who it applies to in order to enforce it. The officer needs this information
when he /she goes to court so would require investigative questions by the officer. Enforcing this type
of signage is not a sure citation like speeding. Mr. Hanson stated a sign might be good just for
someone to think about, but then again signs are routinely ignored. Sergeant Fischer also stated that
our patrolmen do not know how to operate the scales. Mr. Hanson would like Tyler Street blocked off
at 50 or dead ended. Kathy stated she will pass this on to the City Council. She also stated that with
the existing right -of -way we cannot fit a cul -de -sac in.
Chairperson Olson stated he sides with the residents relating to the excess traffic. He agrees with
Sergeant Fischer regarding the signage as the City is "swimming in signs." However, a weight limit
sign may carry some influence with commercial drivers due to the possibility of a citation.
Motioned by Tyler to install weight limit signs on 50` and Tyler, seconded by Olson. Motion
passed unanimously.
DISCUSS ASSIGNING THE EXIT FOR THE FRONTAGE ROAD SOUTH OF 50 AVENUE
AS "RIGHT TURN ONLY." (B. Continued)
Olson recommended that all traffic leave by the south driveway, with entry only on frontage road and
no exit, and no right or left turn. This would alleviate a lot of traffic and still be able to service the
mall with reasonable control. This would be properly posted with signs. Olson stated he does feel
sorry for the mall property owner but he has to side with the residents.
Traffic Commission Minutes April 4, 2010
Page 4
Motioned by Goodman to accept Olson's proposal to designate the southbound frontage road as a one-
way up to the first driveway of Jimmy John's with entry only and no exit and no right or left turn,
seconded by Olson. Three ayes. Doty abstained. Motion carries.
Minutes of the meeting will be forwarded to the City Council who will make the final decision. The right turn
lane will become part of the discussion at the council meeting on Monday, June 13"'. If residents signed in,
staff can notify the City Council of everyone who attended the meeting today.

REPORTS
ASSISTANT CITY ENGINEER
MnDOT has come up with a new way to signify left turns with oncoming traffic. The left turn signal will
now be a yellow flashing arrow. The yellow flashing arrow means it is okay to make a left turn
cautiously.
POLICE CHIEF
None
COMMISSIONERS
The timing on the main semaphores at 53' and Central needs to be changed. There have been complaints
about trying to get onto Central Avenue as it is very difficult. The northbound turn lane has a very short
light. The timing needs to be looked at or sensored.
Goodman stated there are potholes on 41 that were filled a while ago but they are getting bad again.
They are located directly in front of 999 41 Avenue, condo #3.

Motioned by Olson, seconded by Tyler to adjourn the meeting at 6:55 p.m. Motion carried unanimously.

Chapter 2B. REGULATORY SIGNS
2B.1 Application of Regulatory Signs
Regulatory signs shall be used to inform road users of
selected traffic laws or regulations and indicate the applica-
bility of the legal requirements.
Regulatory signs shall be installed at or near where the
regulations apply. The signs shall clearly indicate the
requirements imposed by the regulations and shall be
designed and installed to provide adequate visibility and
legibility in order to obtain compliance.
Regulatory signs shall be retroreflective or illuminated to
show the same shape and similar color by both day and
tight, unless specifically stated otherwise in the text
discussion of a particular sign or group of signs (see Section
2A.13).
The requirements for sign illumination shall not be
considered to be satisfied by street, highway, or strobe
lighting.
2B.2 Design of Regulatory Signs
SUPPORT:
Most regulatory signs are rectangular, with the longer
dimension vertical. The shapes and colors of regulatory
signs are listed in Tables 2A -3 and 2A-4, respectively.
Exceptions are specifically noted in the following Sections.
The use of educational plaques to supplement symbol
signs is described in Section 2A.13.
Changeable message signs displaying a regulatory
message incorporating a prohibitory message that includes a
red circle and slash on a static sign should display a red
symbol that approximates the same red circle and slash as
closely as possible.
The sizes for regulatory signs used on conventional
)ads, expressways, freeways, and low - volume roads, and
rider special conditions shall be as shown in Appendix C
t the back of this Manual.
Compliance Date: December 22, 2413
C�D?AN+CI;;
The Expressway and Freeway sizes should be used for
higher -speed applications to provide larger signs for
increased visibility and recognition.
OPTION:
The Minimum size may be used on low -speed roadways
where reduced legend size would be adequate for the
regulation or where physical conditions preclude the use of
the other sizes.
The Oversized size may be used for those special appli-
cations where speed, volume, or other factors result in
conditions where increased emphasis, improved recognition,
or increased legibility would be desirable.
Signs larger than those shown in this chapter may be used
(see Section 2A.12 and Appendix C).

The Mn/DOT "Standard Signs Manual' (see Map &
Manual Sales Unit, page ii) and the Federal "Standard
Highway Signs" (see Government Printing Office, page ii)
book contains sign sizes and letter heights for regulatory
signs.
When a sign is used to indicate that traffic .is always
required to stop, a STOP (Rl -l) sign shall be used.
The STOP sign shall be an octagon with a white legend
and border on a red background. Secondary legends shall not
be used on STOP sign faces. If appropriate, a supplemental
plaque (RI-3 or R14) shall be used to display a secondary
legend. Such plaques shall have a white legend and border
2B -1 May, 2005
on a red background. If the number of approach legs
controlled by STOP signs at an intersection is three or more,
the numeral on the supplemental plaque, if used, shall
correspond to the actual number of legs controlled by STOP
signs.
At intersections where all approaches are controlled by
STOP signs (see Section 2B.7), a supplemental plaque
(111-3 or RI-4) shall be mounted below each STOP sign.
Compliance Date: January 17, 2004
OPTION:
The ALL WAS' (RI-4) supplemental plaque may be used
instead of the 4 -WAY (Rl -3) supplemental plaque.
suProRT:
The design and application of Stop Beacons are described
in Section 4K.5.

STOP Plaque (R1 X2)
CROSS TRAFFIC
DOES NOT STOP
R142
600 x 300 mm
24" x 12„
The CROSS TRAFFIC DOES NOT STOP sign may be
used at intersections where geometric, topographic or other
conditions exist and motorists approaching a STOP sign
may expect cross traffic to stop. When used, it shall be
installed on the same structure as the STOP sign beneath
all other supplemental plaques.
Its use shall be limited to those intersections where an
engineering and traffic investigation indicate a need.
2B.5 STOP Sign Applications
c�rax;
STOP signs should be used if engineering judgment
indicates that one or more of the following conditions exist:
A. Intersection of a less important road with a main road
where application of the normal right -of -way rule
would not be expected to provide reasonable
compliance with the law;
B. Street entering a through highway or through street;
C. Unsignalized intersection in a signalized area; and/or
D. High speeds, restricted view, or crash records that
indicate a need for control by the STOP sign.
Because the potential for conflicting commands could
create driver confusion, STOP signs shall not be installed at
intersections where traffic control signals are installed and
operating except as noted in Section 4D.1.
Portable or part-time STOP signs shall not be used except
for emergency and temporary traffic control zone purposes.
�um�rrcE:
STOP signs should not be used for speed control.
STOP signs should be installed in a manner that
minimize the numbers of vehicles having to stop. At inter-
sections where a full stop is not necessary at all times, con-
sideration should be given to using less restrictive measures
such as YIELD signs (see Section 2B.8).
F SUPPORII
In many low volume situations with no unusual history of
intersection crashes, no control at the intersections is a cost
effective strategy. Research suggests that at most locations,
increasing the level of intersection control will not improve
safety (see FHWA- RD -81 -084 Stop. Yield and No Control
at Intersections)
CG UIDANCA:1,
Once the decision has been made to install two -way stop
control, the decision regarding the appropriate street to stop
should be based on engineering judgment. In most cases, the
street carrying the lowest volume of traffic should be
stopped.
A STOP sign should not be installed on the major street
unless justified by a traffic engineering study.
srrPPnRr;
The following are considerations that might influence the
decision regarding the appropriate street upon which to
install a STOP sign where two streets with relatively equal
volumes and/or characteristics intersect:
A. Stopping the direction that conflicts the most with
established .pedestrian crossing activity or school
walking routes;
B. Stopping the direction that has obscured vision, dips,
or bumps that already require drivers to use lower
operating speeds;
C. Stopping the direction that has the longest distance of
uninterrupted flow approaching the intersection; and
D. Stopping the direction that has the best sight distance
to conflicting traffic.
The use of the STOP sign at highway - railroad grade
crossings is described in Section 8B.7. The use of the STOP
sign at highway -light rail transit grade crossings is described
in Section 10C.4.
May, 2005 2B-2
2B.6 STOP Sign Placement
The STOP sign shall be installed on the right side of the
approach lane to which it applies. When the STOP sign is
installed at this required location and the sign visibility is
restricted, a Stop Ahead sign (see Section 2C.29) shall be
installed in advance of the STOP sign.
The STOP sign shall be located as close as practical to the
intersection it regulates, while optimizing its visibility to the
road user it is intended to regulate.
STOP signs and YIELD signs shall not be mounted on the
same post.
GUMViM
There should be no sign mounted back -to -back with a
STOP sign in a manner that obscures the shape of the STOP
sign.
Compliance Date: December 22, 2013
SUPPORT:
Section 2A.16 contains additional information about
separate and combined mounting of other signs with STOP
signs.
Stop lines when used to supplement a STOP sign, should
be located at the point where the road user should stop (see
Section 3B.16).
If only one STOP sign is installed on an approach, the
STOP sign should not be placed on the far side of the inter-
section.
Where two roads intersect at an acute angle, the STOP
sign should be positioned at an angle or shielded so that the
legend is out of view of traffic to which it does not apply.
Where there is a marked crosswalk at the intersection, the
STOP sign should be installed approximately 1.3 m (4 ft) in
advance of the crosswalk line nearest to the approaching
traffic.
opriox:
At wide - throat intersections or where two or more
approach lanes of traffic exist on the signed approach,
observance of the stop control may be improved by the
installation of an additional STOP sign on the left side of the
road and/or the use of a stop line. At channelized intersec-
tions, the additional STOP sign may be effectively placed on
a channelizing island.
SUPPORT:
Figure 2A -2 shows examples of some typical placements
of STOP signs.
25.7 Muldway Stop Applications
suPPORT
Multiway stop control can be useful as a safety measure
at intersections if certain traffic conditions exist. Safety
concerns associated with multiway stops include
pedestrians, bicyclists, and all road users expecting other
road users to stop. Multiway stop control is used where the
volume of traffic on the intersecting roads is approximately
equal.
The restrictions on the use of STOP signs described in
Section 213.5 also apply to multiway stop applications.
GUInANCF.:
The decision to install multiway stop control should be
based on an engineering study.
The following criteria should be considered in the
engineering study for a multi -way STOP sign installation:
A. Where traffic control signals are justified, the multi-
way stop is an interim measure that can be installed
quickly to control traffic while arrangements are being
made for the installation of the traffic control signal.
B. A crash problem, as indicated by 5 or more reported
crashes in a 12 -month period that are susceptible to
correction by a multi -way stop installation. Such
crashes include right- and left -turn collisions as well
as right -angle collisions.
C. Minimum volumes:
1. The vehicular volume entering the intersection from
the major street approaches (total of both
approaches) averages at least 300 vehicles per hour
for any 8 hours of an average day, and
2. The combined vehicular, pedestrian, and bicycle
volume entering the intersection from the minor
street approaches (total of both approaches)
averages at least 200 units per hour for the same 8
hours, with an average delay to minor -street
vehicular traffic of at least 30 seconds per vehicle
during the highest hour, but
3. if the 85th- percentile approach speed of the major -
street traffic exceeds 40 mph, the minimum
vehicular volume warrants are 70 percent of the
above values.
D. Where no single criterion is satisfied, but where
Criteria B, C.1, and C.2 atd all satisfied to 80 percent
of the minimum values. Criterion C.3 is excluded
from this condition.
211-3 May, 2005
OPTION:
Other criteria that may be considered in an engineering
study include:
A. The need to control left -turn conflicts;
B. The need to control vehicle/pedestrian conflicts near
locations that generate high pedestrian volumes;
C. Locations where a road user, after stopping, cannot
see conflicting traffic and is not able to reasonably
safely negotiate the intersection unless conflicting
cross traffic is also required to stop; and
D. An intersection of two residential neighborhood
collector (through) streets of similar design and
operating characteristics where multiway stop control
would improve traffic operational characteristics of
the intersection.
2B.8 YIELD Sign (RI-2)
R1 -2
900 x 900 x 900 mm
36" x 36" x 36"
sz.ar`naleu:
The YIELD (RI-2) sign shall be a downward - pointing
equilateral triangle with a wide red border and the legend
YIELD in red on a white background.
SUPPORM
The YIELD sign assigns right -of -way to traffic on certain
approaches to an intersection. Vehicles controlled by a
YIELD sign need to slow down or stop when necessary to
avoid interfering with conflicting traffic.
2B.9 YIELD Sign Applications
OPTION:
YIELD signs 'may be used instead of STOP signs if
engineering judgment indicates that one or more of the
following conditions exist:
Compliance Date: January 11, 2011
A. When the ability to see all potentially conflicting
traffic is sufficient to allow a road user traveling at the
posted speed, the 85th- percentile speed, or the
statutory speed to pass through the intersection or to
stop in a reasonably safe manner.
B. If controlling a merge -type movement on the entering
roadway where acceleration geometry and/or sight
distance is not adequate for merging traffic operation.
C. At the second crossroad of a divided highway, where
the median width is 9 in (30 ft) or greater. A STOP
sign may be installed at the entrance to the first
roadway of a divided highway, and a YIELD sign may
be installed at the entrance to the second roadway.
D. At an intersection where a special problem exists and
where engineering judgment indicates the problem to
be susceptible to correction by the use of the YIELD
sign.
AYIELD (RI -2) sign shall be used to assign right -of -way
at the entrance to a roundabout intersection.
2B.10 YIELD Sign Placement
The YIELD sign shall be installed on the right side of the
approach to which it applies. YIELD signs shall be placed on
both the left and right sides of approaches to roundabout
intersections with more than one lane on the signed
approach where raised splitter islands are available on the
left side of the approach. When the YIELD sign is installed
at this required location and the sign visibility is restricted, a
Yield Ahead sign (see Section 2C.29) shall be installed in
advance of the YIELD sign.
The YIELD sign shall be located as close as practical to
the intersection it regulates, while optimizing its visibility to
the road user it is intended to regulate.
YIELD signs and STOP signs shall not be mounted on the
same post.
There should be no sign mounted back -to back with a
YIELD sign in a manner that obscures'the shape of the
YIELD sign.
Compliance Date: December 22, 2013
SuProtrr:
Section 2A.16 contains additional information about
separate and combined mounting of other signs with YIELD
signs.
YIELD lines, when used to supplement a YIELD sign,
should be located at a point where the road user should yield
(see Section 311.16).
Where two roads intersect at an acute angle, the YIELD
sign should be positioned at an angle, or shielded, so that the
legend is out of view of traffic to which it does not apply.
Except at roundabout intersections where there is a
marked crosswalk at the intersection, the YIELD sign should
be installed in advance of the crosswalk line nearest to the
approaching traffic.
