TO: TRAFFIC COMMISSION
FROM: KATHY GARCIA, DIRECTOR OF PUBLIC WORKS
DATE: April 6, 2017
SUBJECT: REVIEW OF TRAFFIC CONDITIONS AT HART AVENUE AND STEELE
STREET
BACKGROUND
The Traffic Commission received a request from a resident to review traffic conditions at Hart
Avenue and Steele Street. A resident submitted a request to the City stating that he observed
speeding vehicles along Hart Avenue between Guess Street and Valley Boulevard. The
resident is requesting that the City install traffic calming measures such as STOP signs on the
north and south leg of the intersection at Hart Avenue and Steele Street or speed humps to
slow down the speed of the vehicles traveling along Hart Avenue. A traffic study was
conducted by traffic consultant JLS at the location. The study included a warrant study to
determine if the installation of all-way STOP control is appropriate.
STAFF RECOMMENDATION
In response to the resident's request, a traffic investigation of the intersection of Hart Avenue
and Steele Street was conducted using guidelines or Warrrants from the 2014 California
MUTCD for installation of All-Way Stop Signs. A field visit was conducted to evaluate site-
specific conditions, such as traffic volumes, collisions history, sight distance, existing stop
signs and physical obstructions. The current traffic conditions at this intersection did not meet
the criteria for all-way stop control. Traffic volumes are also well below the minimum
requirements for installation of all-way stop controls. Based on the above, the traffic consultant
did not recommend all-way stop control at this intersection.
However, the speed samples did determine that there is a speeding issue along Steele Street,
therefore, staff is recommending that 25 MPH speed limit signs be installed on Steele Street
for eastbound and westbound traffic and on Hart Avenue at Guess Street for northbound
traffic. The speed limit signs will remind motorist of the speed limit and to slow down. It is also
recommended that DIP (W8-2) signs be installed on Hart Avenue north and south of Steele
Street to warn motorists to slow down approaching the DIP. See Attachment 4 for the
Proposed Recommendations.

STOP controlled in the eastbound and westbound direction. There is a cross gutter dip in the
north leg of the intersection at Hart Avenue and Steele Street that also serves as a speed
calming device. From the intersection at Hart Avenue and Steele Street approximately 285-feet
north, the intersection of Hart Avenue and Valley Boulevard is signalized. Approximately 380-
feet south, the intersection of Hart Avenue and Guess Street is STOP controlled in the
northbound and southbound directions and uncontrolled in the eastbound and westbound

WARRANT STUDY ANALYSIS
A field investigation and counts were conducted at the intersection of Hart Avenue and Steele
Street on Tuesday, October 11, 2016 to determine existing geometric and traffic control
conditions.
Based on the analysis of these counts, it was determined that the peak hours of traffic
movements were as follows:
Morning Peak Hour Afternoon Peak Hour

Hart Ave N/O Steele St (NB) (7:30am-8:30am) 113 (5:OOpm-6:OOpm) 92

Attachment 4 includes a full warrant analysis for the installation of an all-way stop control at
Hart Avenue and Steele Street.
In addition, an accident investigation was conducted using the last three (3) available years
from SWITRS (Statewide Integrated Traffic Records System) records for the intersection of
Hart Avenue and Steele Street. The record research found that there were no vehicle or
pedestrian accidents within this time frame.
Findings
The criteria for determining if an all-way stop control is warranted is based on several factors
set by the California Manual of Uniform Traffic Control Devices (MUTCD) Section 26.07.
These factors include an analysis of minimum volumes of traffic on each street approach,
accidents, vehicles speeds, pedestrian traffic and potential sight obstructions.
Based on a review of these factors, it was determined that the intersection does not meet
minimum volume or accidents thresholds as determined by the MUTCD for the installation of
all-way stop control at Hart Avenue and Steele Street. This information is summarized below:
A. Traffic Control Signals are justified (Not Met)
B. A crash problem exists as indicated by 5 or more accidents in a 12- (Not Met)
month period
C. Minimum Volumes are met if: (Not Met)
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, (Not Met)
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.
If the 85th percentile approach speed of the major-street exceeds 40 (Not Met)
mph the minimum volumes are 70 percent of the above values.
RADAR SPEED SURVEY
To determine actual speeds along Hart Avenue and Steele Street, a radar speed survey was
conducted on Hart Avenue north and south of Steele Street and on Steele Street east and
west of Hart Avenue on Tuesday, October 11, 2016.

The table below shows the 2016 speed survey results:
Radar Speed Survey for Hart Avenue and Steele Street

2 Hart Avenue N/O Steele Street SB 10/11/16 21 18 25 Prima Facie
3 Hart Avenue SIO Steele Street NB 10/11/16 30 24 25 Prima Facie
4 Hart Avenue 5/0 Steele Street SB 10/11/16 24 21 25 Prima Facie
5 Steele Street E/O Hart Avenue EB 10/11/16 33 27 25
6 Steele Street E/O Hart Avenue WB 10/11/16 35 28 25
7 Steele Street W/O Hart Avenue EB 10/11/16 35 29 25
8 Steele Street W/O Hart Avenue WB 10/11/16 34 28 25
As shown in the table above, the speed samples taken on October 11, 2016 show that the
85th percentile speed of vehicles is at 20-24 MPH for Hart Avenue north of Steele Street in
both directions which is below the prima facie speed limit of 25 MPH but for Hart Avenue south
of Steele Street in the northbound direction the 85th percentile speed of vehicles is at 30 MPH.
The speed samples taken also show that the 85th percentile speed of vehicles is at 33-35
MPH for Steele Street east and west of Hart Avenue in both directions which is above the
posted speed limit of 25 MPH.
The speed samples determined that there is a speeding issue along Steele Street therefore it
is recommended that 25 MPH speed limit signs be installed on Steele Street east of
Rosemead Blvd for eastbound traffic and west of Rio Hondo for westbound traffic and on Hart
Avenue at Guess Street for northbound traffic. The speed limit signs will remind motorist of the
speed limit and to slow down. It is also recommended that DIP (W8-2) signs be installed on
Hart Avenue approaching Steele Street to warn motorists to slow down for the incoming DIP.
