SUBJECT: Resolution Accepting Completion of the Traffic Signal Video Detection
Replacement Portion of Project C16101823, Pavement Restoration 18/19, by DC
Electric Group, Inc.
RECOMMENDATION
It is recommended that the City Council adopt the attached Resolution Accepting Completion of
the Traffic Signal Video Detection Replacement Portion of Project C16101823, Pavement
Restoration 18/19, by DC Electric Group, Inc.
BACKGROUND
This project includes the full reconstruction of Sonoma Mountain Parkway from Corona Road to
Campus Circle South including the section from Wyndham Way to East Washington Street. The
Traffic Signal Video Detection Replacement Project was the first phase of the Pavement
Restoration 18/19 CIP project, C16101823. To prepare for the upcoming paving project it was
determined that the existing traffic signal control equipment needed to be upgraded. Replacing
the existing in -ground vehicle inductive -loop detectors with vehicle detection cameras (VDC)
allows for the functionality of the traffic signals before, during and after construction. This signal
upgrade was consistent with the City's efforts to upgrade its older inductive -loops with VDCs at
signal intersections.
The proposed action supports the City Council Goal #85 — "Improve traffic safety through
proactive education, engineering, and enforcement strategies."
DISCUSSION
An inductive -loop detector consists of wire "coiled" to form a loop that is installed slightly under
the surface of the roadway. As vehicles drive over a loop detector, the loop field changes,
detecting the presence of a vehicle and alerting the overhead signals. The current industry
standard for traffic signal control has shifted from these loop detectors to video detection
cameras (VDC). VDCs are mounted on the traffic signal pole and utilize the video image and
predefined detection zones to detect vehicles as well as other roadway users including bicyclists
and pedestrians for the sole purpose of vehicle and bicycle detection to actuate the traffic signal
When an object enters a detection zone, the pixel value within the zone changes alerting the
overhead signals.
This shift to VDCs from loop detectors is advantageous for the following reasons. First, during
construction loop detectors are usually removed or damaged during the work that is conducted
prior to paving. All functionality of the signals is lost and usually not restored until the end of the
project. VDCs allow for detection zones to be adjusted as the travel lanes continually shift during
construction. Traffic signal operation will remain in effect during construction and the overall
disruption to traffic will be minimized.
Second, the re -installation of loop detectors would require cutting into the roadway to place the
wires. Doing so creates the potential for water intrusion and eventually the potential failure of the
pavement.
The final construction contract is $195,950 which includes one change order for $46,200 for
additional video detection cameras and renegotiation of existing unit price cost. There are no
disputed claims and the project was completed satisfactorily without any significant incidents.
PUBLIC OUTREACH
On May 20, 2019 Petaluma Police Department issued a news release to address community
concerns about the use of video detection cameras. In this release they emphasized that the
technology was to be solely use for vehicle and bicycle detection to actuate the traffic signal. The
action to award this contract was brought before Council on January 28, 2019, a publicly -noticed
meeting
FINANCIAL IMPACTS
With the award of the Traffic Signal Video Detection Replacement contract on January 28, 2019,
Council approved a project budget of $171,750, which was funded by Street Maintenance and
Senate Bill 1 (SB -1), also known as the Road Maintenance and Repair Account (RMRA). With
the addition of one change order in the amount of $46,200, the revised project budget was
$217,250.

Community Concerns Regarding Recently Installed Traffic Cameras
Over the past few weeks, the Petaluma Police Department has become aware of discussion on social
media regarding the recent installation of vehicle detection cameras (VDC) in intersections along
Sonoma Mountain Parkway from Maria Drive to E. Washington St. Much of the discussion stemmed
from concerns over the funding for the cameras, their scope of use, data -sharing, privacy, and
oversight.
In attempt to answer a number of these questions we have consulted with our partners at the City of
Petaluma's Public Works Department. The following is information we have learned from our traffic
engineers regarding the VDCs.
These new vehicle detection cameras (VDC) were installed as part of the reconstruction of Sonoma
Mountain Parkway. In order to reconstruct the roadway the traffic sensor equipment embedded in the
roadway was going to have to be removed. The VDC were installed to replace the existing traffic
sensors prior to the larger roadway reconstruction project so we could maintain functionality of the
traffic signal before and after construction. The new VDC are mounted on the traffic poles and utilize
the real time video images and a predefined detection zone to detect motion when vehicles and/or
bicyclists. The detection of motion is what prompts a notification for the traffic signals to cycle. The
video images are not recorded or monitored.
The installation of VDCs was approved as part of the reconstruction of Sonoma Mountain Parkway by
City Council on January 28, 2019 and additional information is available on line at

2f23-110-b021-0050569183fa or by contacting the Petaluma Public Works Department at 778-4303.
Many of the concerns expressed regarding the VDCs made assumptions that the Petaluma Police
Department was using and monitoring the images captured by the cameras. While that is not currently
the case, the Petaluma Police Department prides itself in being a proactive and progress police
department. We are constantly evaluating opportunities to augment our limited staffing with
technological solutions that help us be more efficient through intelligence led policing, reduce crime,
and improve the safety of our community and officers. As we consider and evaluate such technology
we welcome feedback and comment from the community.
