FIELD OBSERVATIONS
On Thursday, March 21, 2024, a field review was conducted at the intersection of Marshall Street and
Ivar Avenue. The review consisted of reviewing the conditions of existing signage, roadway conditions,
existing red curb, and review of vehicle movements in the area. At the intersection with Marshall Street,
there is a portion of Ivar Avenue that has white side striping. The white side striping creates an 8-foot
wide buffer on both sides of the street for approximately 50-feet, which leaves a travel lane of
approximately 10-feet wide for northbound and southbound vehicles.
The existing red curb was reviewed at the intersection to help determine if there is enough line of sight
for vehicles traveling along Ivar Avenue approaching Marshall Street.

LINE OF SIGHT ANALYSIS
A Line-of-Sight analysis consists of reviewing the existing conditions a driver encounters when
approaching an intersection to turn onto the other street and determining if there is limited view for the
driver turning. The driver of a vehicle approaching or departing from an intersection or driveway should
have an unobstructed view of the intersection, including any traffic control devices, and sufficient lengths
along the intersecting highway to permit the driver to anticipate and avoid potential obstructions. Any
object within the sight triangle that would obstruct the driver’s view of an approaching vehicle should be
removed or modified per the Manual on Uniform Traffic Control Devices. Obstructions within sight
triangles could be buildings, vehicles, hedges, trees, bushes, tall crops, walls, fences, or parked cars. A
parked vehicle extends approximately 7-feet from the curb, so it’s necessary to consider the width of a
vehicle when determining the amount of red curb needed to obtain a clear line of sight. On intersections
in urban areas where street parking is allowed, the common practice by motorists after stopping at the
curb and watching and yielding for any potential pedestrians crossing on the sidewalk, is to pull a sufficient
distance forward in the parking lane to have a better view of oncoming traffic. Figure 6 presents an
example of a clear sight triangle at an intersection.

TRAFFIC CALMING DEVICES AND STRATEGIES
Traffic calming is the process of reducing vehicle speeds through the use of both passive devices, such as
signs and striping, and physical devices such as changes in road elevation or path. As part of this study,
traffic speeds, accidents and traffic volumes were used to assess existing conditions along this segment.
The type, design and placement of traffic calming devices depend upon the road classification, desired
traffic speed and types of traffic issues along Marshall Street at Ivar Avenue. The following is a list of
common traffic calming measures usually deployed to reduce speeding, increase visibility of signs, and
decrease running of Stop signs.
1) Traffic Education Campaign
2) Signage and Pavement Legends
3) Larger Dimension Signs or Beacons on Signs
4) Traffic Striping
5) Radar Feedback Signs
6) Targeted Police Enforcement
ALL-WAY STOP CONTROL CRITERIA FOR DETERMINING IF STOP CONTROL IS WARRANTED
Traffic control devices work in concert with the basic “rules of the road” contained in traffic laws and
ordinances. The California Manual of Uniform Traffic Devices (CAMUTCD) describes applications,
warrants, and placement of STOP signs (R1-1). The STOP sign is a regulatory device that is used when
traffic is required to stop. STOP signs are used to assign right-of-way at an intersection. Multi-way control
is used where the volume of traffic on the intersecting roads is approximately equal. Stop signs are not
used as a speed control device. Since a STOP sign causes inconvenience to motorists, it should be used
only where warranted. There are several factors that an intersection needs to meet for the consideration
of all-way stop control; criteria include minimum volumes on each of the street approaches, collision
investigation, speed of traffic, number of pedestrians and potential sight obstructions.
All-Way Stop Installation
The following briefly outlines the Criteria for the installation of All-Way stop warrants.
The placement of All-Way stop control is warranted when1 minimum volume thresholds are exceeded:
A. Traffic control signals are justified
B. A crash problem exists as indicated by 5 or more collisions in a 12-month period
C. Minimum Volumes are met if:
1. Volume entering intersection from the major approach (total of both approaches) averages 300
vehicles per hour for any 8 hours of an average day. And
2. The combined vehicle, pedestrian and bicycle volumes entering the intersection from the minor
street approaches averages at least 200 units per hour for the same 8 hours.
1 California Manual of Uniform Traffic Control Devices, Section 2B.07 Multiway Stop Applications
ALL WAY STOP REVIEW FOR IVAR AVENUE AND MARSHALL STREET
CITY OF ROSEMEAD
Prepared By: Transtech Engineers, Inc. | Page 11 of 20
3. If the 85th percentile approach speed of the major street exceeds 40 mph the minimum volumes
are 70 percent of the above values.
Peak hours used in Table 5 are from ADT (Average Daily Traffic) counts taken on each approach for
Marshall Street at Ivar Avenue to determine if the intersection met volume warrants for all-way stop
installation. Only those pedestrians walking on the uncontrolled lanes are considered in the following
table. As shown in the table the intersection did not meet volume warrants for all-way stop control.

RECOMMENDATIONS
After a thorough review of existing field conditions, and data collection this intersection of Marshall
Street and Ivar Avenue does not meet the requirements for an all-way stop installation. The criteria that
were not met includes a low number of collisions in the last 12-month period, as well as a low number
of traffic traveling along Ivar Avenue approaching Marshall Street, determined by the Average Daily
Traffic (ADT) counts shown in Table 2.
However, it was determined that additional traffic calming measures may be installed at the intersection
of Marshall Street and Ivar Avenue to help improve existing conditions in the area. Please refer to the
Recommendations below for a visual demonstration of the proposed conditions.
1. INSTALL “CROSS TRAFFIC DOES NOT STOP” (W4-4P) PLAQUE & RED REFLECTIVE STRIP below the
existing stop sign on Ivar Avenue at Marshall Street, as shown in Figure A.
Refer to the Recommendations below for a visual demonstration of the
proposed condition.
• A. Install “Cross Traffic Does Not Stop” Plaque at the northwest corner
of the intersection, beneath the existing stop sign on Ivar Avenue at
Marshall Street.
• B. Install Red Reflective Strip on existing stop signpost on the northwest
corner of the intersection of Ivar Avenue and Marshall Street.
2. INSTALL “30” PAVEMENT LEGEND adjacent to the existing 30 mph speed limit sign along Marshall
Street for eastbound traffic, approximately 175-feet east of the intersection with Muscatel
Avenue.
3. INSTALL “30” PAVEMENT LEGEND adjacent to the existing 30 mph speed limit sign along
Marshall Street for westbound traffic, approximately 170-feet west of the intersection with
Rosemead Boulevard.
