SUBJECT: Traffic Review on Temple City Boulevard between South of Valley Boulevard to Loftus
Drive
INTRODUCTION
The City of Rosemead received a resident request to conduct a traffic review evaluate installation of speed
humps along the segment of Temple City Boulevard between just South of Valley Boulevard to Loftus
Drive as shown in Figure 1. In response to this request and on behalf of the City, engineering staff
completed a traffic review and recommended appropriate traffic calming measures along this segment of
Temple City Boulevard. The traffic review included an analysis of existing roadway conditions, a review of
approximately 3 years of available collision data, average daily traffic (ADT) counts, a 24-hour Speed
Survey, as well as an examination of the field conditions.

COLLISION INVESTIGATION
A Collision History Analysis and investigation was conducted for the subject location. Collision data was
obtained from the computerized collision records system maintained by the State of California called the
Statewide Integrated Traffic Records Systems (SWITRS). The collision analysis was conducted over
approximately a 3 -year period between August 2020 through August 2022 (available data at the time of
traffic review). A review of available collisions that were reported to SWITRS within 50 feet of each
intersection and midblock along Temple City Boulevard from South of Valley Boulevard to Loftus Drive
was conducted. Based on the Collision History Analysis and investigation, it was determined that there
were 11 total collisions reported. A summary breakdown of the number of collisions within the studied
segment are listed below and shown in Table 1 and depicted in Figure 3.
2022 - 4 collisions
2021- 4 collisions
2020 - 3 collisions

Traffic Review on Temple City Boulevard between South of Valley Boulevard to Loftus Drive
Boulevard from South of Valley Boulevard to Loftus Drive carries more traffic and higher speed than would
be safe for installation consideration. The Speed Hump criteria outlines that a street must have a posted
speed limit of 25 mph or less and carry less than 3,000 vehicles per day. Temple City Boulevard from South
of Valley Boulevard to Loftus Drive has a posted speed of 40 mph with 20,100 vehicles per day. Instead,
other traffic calming measures were recommended and determined to be a more appropriate
improvement to address the resident concerns.
TRAFFIC CALMING DEVICES AND STRATEGIES
Traffic calming is the process of reducing vehicle speeds using 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, collisions, 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 Temple City Boulevard from South of Valley Boulevard to Loftus
Drive. The following is a list traffic calming measures that are recommended for this segment:
1) Larger Dimension Signs: Installation of larger dimensioned signage are recommended as treatments
to increase the motorist's awareness and other Driver conditions by highlighting various areas of the
roadway. All sign dimensions should comply with the dimensions specified in the California Manual of
Uniform Traffic Control Devices (CAMUTCD) Table 213-1 Regulatory Sign and Plaque Sizes. The larger
sizes are shown in the multi -lane column as 36"x36" for stop signs and 30"x36" for speed limits.
Table 213-1. Regulatory Sign and Plague Sizes (Sheet 1 of 4)
2) Radar Feedback Signs: Radar feedback signs are an effective way to alert Drivers of their speed. The
speed of each passing vehicle is taken and displayed next to the posted speed limit.
3) Targeted Police Enforcement: The police department deploys officers to perform enforcement on
residential streets for at least an hour a day.
After a thorough review of existing field and traffic conditions and per the California Manual on Uniform
Traffic Control Devices (CAMUTCD), California Vehicle Code (CVC), based on the traffic review and
engineering judgement, it was determined that the segment of Temple City Boulevard from South of
Valley Boulevard to Loftus Drive would benefit from additional traffic calming measures and signage
installation. Please refer to Figure 4 for a conceptual exhibit representation of the proposed
recommendations.
