SUBJECT: PROFESSIONAL SERVICES AGREEMENT WITH KLD ENGINEERING,
P.C., IN THE AMOUNT OF $576,204 TO PROVIDE AN ADAPTIVE
TRAFFIC CONTROL SYSTEM TO COMPLETE PHASE 2 OF THE
INTELLIGENT TRANSPORTATION SYSTEM (ITS) MASTER PLAN,
AUTHORIZE A 10% CONTINGENCY, AND ADOPT A CATEGORICAL
EXEMPTION PURSUANT TO SECTION 15301(c) OF THE CALIFORNIA
ENVIRONMENTAL QUALITY ACT (CEQA)
Recommendation: Approve
SUMMARY
Approximately two years ago, the City of Arcadia began implementation of Phase 2 of
the Intelligent Transportation System (ITS) Master Plan utilizing a grant from Los
Angeles County Metropolitan Transportation Authority (Metro) to add elements to the
City's local Traffic Control System (TCS). Phase 2 was divided into two projects. The
first project was the design and installation of TCS elements for an additional 15 traffic
signals and 12 video cameras as well as the installation of conduit and fiber optics lines
to expand the City's network. The second project of Phase 2 is to purchase and
implement an adaptive traffic control system. An adaptive system involves new
technology that provides more efficiency and flexibility for traffic signal operations.
The City recently issued a formal request for proposals to five qualified traffic system
engineering consultants, and received four (4) proposals to provide professional
services for an adaptive traffic control system. After extensive review of the proposals,
KLD Engineering, P.C. was selected to provide design and implementation of the
adaptive system in the amount of $576,204.

BACKGROUND
The first part of the implementation of Phase 2 of the City's ITS Master Plan was to
design and install conduit, fiber optics lines, and CCTV cameras, and connect 15 more
traffic signals to the City's TCS. This work was completed in June 2013. With these
improvements, the City now has 49 of its 59 traffic signals connected to the system
using the TransSuite software with the ability to coordinate signal timing, make
immediate changes, and respond to problems quickly. Also, the City can monitor traffic
flow conditions by use of video and graphical map interfaces. Lastly, the City's TCS is
currently sending daily traffic signal information to the Los Angeles County Information
Exchange Network (IEN), providing a regional benefit to traffic management throughout
the San Gabriel Valley.
The City of Arcadia now has the ability to expand its TCS to include an adaptive traffic
control system to automate traffic signal response to traffic demands on the system, as
well as improve overall performance of existing streets in the network. Specifically, an
adaptive system can provide the following features:
• React instantly to changing traffic patterns instead of staying with the current
fixed (time of day) signal timing
• Optimize and adjust signal timing in real -time when traffic patterns change
• Accommodate side street traffic with less delay, especially when traffic on the
primary streets is minimal or has random gaps
As traffic congestion in Arcadia continues to grow, it is becoming increasingly important
that the City continue to improve management of traffic flow and reduce travel times in
order to maximize the efficiency of City streets. The project scope, as currently
approved by Metro, is to design and install an adaptive traffic control system at key
intersections, primarily around the proposed Arcadia Gold Line Station and connections
to the 1 -210 freeway (see exhibit, yellow highlighted intersections). The selected traffic
signals will be upgraded with new controllers and software to enhance the system.
DISCUSSION
The City issued a formal request for proposals to five qualified traffic system
engineering consultants, and received four proposals. The City requested that the
consultants propose their adaptive systems on a unit cost per intersection basis. The
unit costs of each of the four proposals are as follows:

Upon review of the four proposals received, the City selected the ACDSS system,
developed by KLD Engineering, P.C. This system provides the following features:
• Compatible with existing traffic control infrastructure and multiple types of
controllers
• Able to utilize various detection methods (i.e. video and loop)
• Capable of handling unsaturated and oversaturated traffic conditions
• Capable of communication with multiple intersections on the grid networks, not
just linear corridors
• User defined periods to run the system according to a schedule, and the ability to
turn on or off manually
• Capable of handling short -term traffic variations (i.e. special events)
ACDSS is compatible with the City's existing TransSuite TCS software, as an add -on
module. Communications between ACDSS and the traffic signal controllers are
accommodated through the TransSuite system. This means that no additional
communication improvements are required, which is not necessarily the case with other
proposers. While the City has not worked with KLD previously, New York City contracts
with KLD and recommends them highly. Based on KLD's unit cost, the City requested
33 intersections to be included in their proposal.
ENVIRONMENTAL IMPACT
This project is categorically exempt per Section 15301(c) of the California
Environmental Quality Act (CEQA), covering alterations or improvements to existing
facilities. This is because it is replacing equipment and upgrading existing traffic signals
with an adaptive traffic control system to improve the efficiency of the existing road
and traffic signal network.
FISCAL IMPACT
The project was budgeted in the FY 2009 -10, FY 2010 -11, and FY 2011 -12 Capital
Improvement Program, with $1,976,000 from Metro and $711,000 in Proposition C
funds, for a total budget of $2,687,000. Approximately $1,827,000 has been spent and
encumbered thus far on design, construction, and other portions of the overall project.

With the proposal amount of $576,204, and an additional 10% contingency, there are
sufficient funds to cover the design and implementation of this project.
RECOMMENDATION
Authorize and direct the City Manager to execute a Professional Services Agreement
with KLD Engineering, P.C., in the amount of $576,204 to provide an Adaptive Traffic
Control System to complete Phase 2 of the Intelligent Transportation System (ITS)
Master Plan, authorize a 10% contingency, and adopt a categorical exemption pursuant
to Section 15301(c) of the California Environmental Quality Act (CEQA).
