4. Functionality
a. Fusion Sensors
i. Fusion sensors shall detect, classify, and track vehicles and vulnerable
road users (VRUs) located between 40 ft and 720 ft from the sensor.
Fusion sensors shall classify vehicles and VRUs as cars, trucks, buses,
motorcycles, bicycles, or pedestrians, and track their location and
trajectory (direction and speed). To minimize sensor-to-cabinet
communications, the detection, classification, and tracking data shall be
processed in the fusion sensor, not the CIU.
ii. All detection, classification, and tracking for an approach shall be
performed by one fusion sensor. Systems that require multiple sensors
per approach, including but not limited to systems that use different
sensors for stop line and advance detection, systems that require
different quantities of sensors for different intersection widths, and
systems that use different sensors for major streets and minor streets, are
not compliant with this specification.
iii. Fusion sensors shall fuse video and radar to provide synthesized
detection, classification, and tracking data. Non-fused hybrid sensors that
only provide separate detection, classification, and tracking data for video
and radar, or otherwise treat video and radar as independent, non-fused
sensors, are not compliant with this specification.
b. Cabinet Interface Units
i. Cabinet interface units shall aggregate intersection-level communications,
data, and processing. Communications between CIUs and fusion sensors
shall occur over a VPN with AES-256 encryption using Wi-Fi with WPA2-
AES security. Communications between CIUs and transportation field
cabinets shall use the NEMA TS 2 Port 1 and ITS/ATC 5301 Serial Bus 1
synchronous serial bus protocols. CIUs shall be capable of logging all
communications on the synchronous serial bus including frames
transmitted by other secondary stations. They shall automatically
configure synchronous serial communications for either the TS 2 Port 1
protocol or the ITS/ATC 5301 Serial Bus 1 protocol and shall detect any
other I/O interface units (BIUs or SIUs) currently in use to prevent
duplicate synchronous serial bus address assignments.
ii. CIUs shall provide browser user interfaces to monitor, configure, and
control the CIU, fusion sensors, and sensor power units. Access to CIU
browser user interfaces shall be restricted via username and password
authentication.
iii. CIUs shall provide high-definition RTSP video streams, one for each
fusion sensor, as well as a quad view of four fusion sensors. Detection
zones shall be displayed in video streams with their actuation state
represented by different colors. Signal state (channel state) shall be
34 41 00 - 48 DCR15
displayed in video streams using icons labeled with phase or overlap
numbers.
c. Cloud Portal
i. The cloud portal shall provide centralized monitoring, configuration, and
control of distributed systems, as well as centralized data storage and
reporting. Communications between the cloud portal and distributed
systems shall occur over VPNs with AES-256 encryption. The cloud
portal shall be hosted on AWS in the US or Canada using a discrete
tenant for each infrastructure owner/operator (IOO), thereby ensuring
complete isolation of the IOO’s data from that of any other IOO. Cloud
portals employing multi-tenant architecture are not compliant with this
specification.
ii. The cloud portal shall provide a browser user interface. Access to the
browser user interface shall be restricted via username and password
authentication.
d. Object Detection
i. The system shall detect traffic (vehicles and VRUs) in user-defined zones
located in approach lanes, departure lanes, and crosswalks. Detection
zones shall support presence and pulse modes, extension, and delay.
ii. The system shall report the occupancy of detection zones via detector
outputs. When a detection zone is occupied, it shall be considered
actuated and its detector outputs shall be ON; otherwise, its detector
outputs shall be OFF. The system shall support user-defined zone-to-
output mappings, including zones mapped to multiple outputs and
multiple zones mapped to the same output.
iii. The system shall support user-defined mappings between detector
outputs and inputs of NEMA TS 1, NEMA TS 2, Model 33x, ITS, and ATC
5301 transportation field cabinets. Transportation field cabinet inputs will
be mapped in actuated signal controllers to detectors, custom logic, and
other input functions.
iv. Detection accuracy shall be at least 98% under typical environmental
conditions, defined as time with no false actuations (zone actuated but
not occupied) or missed actuations (zone occupied but not actuated)
versus total time, expressed as a percentage. Detection accuracy shall
have been evaluated at a minimum of six traffic control signals on roads
open to public travel, where each traffic control signal is owned and
operated by a different IOO. Traffic control signals on roads not open to
public travel including but not limited to those at test beds/tracks,
research laboratories, and signal maintenance facilities do not satisfy this
requirement. Upon request, the Manufacturer shall provide engineering
reports for the detection accuracy evaluations that include methodologies
and results. The reports shall be attested by a licensed Professional
Engineer employed by the Manufacturer.
34 41 00 - 49 DCR15
v. Upon any anomaly or malfunction that affects its ability to report the
occupancy of detection zones, the system shall actuate the affected
detection zones by turning their detector outputs ON and report them as
failed via the NEMA TS 2 and ITS/ATC synchronous serial bus protocols
by turning their status outputs OFF.
vi. The system shall detect vehicles in the dilemma zone (“Dilemma Zone
Detection”). Dilemma Zone Detection shall be implemented via Dilemma
Detection Zones, where a Dilemma Detection Zone has a user-defined
distance upstream of the stop line, speed range, and extension time.
Each Dilemma Detection Zone shall be capable of being associated with
one or more inputs in the transportation field cabinet. When a vehicle
enters a Dilemma Detection Zone and the speed of the vehicle is within
the range of speeds for the Dilemma Detection Zone, the system shall
actuate the inputs associated with the Dilemma Detection Zone for the
associated extension time. By associating the inputs with extension
detectors in actuated signal controllers, phases can be extended until
vehicles are clear of the dilemma zone.
vii. The system shall detect pedestrians in crosswalks using Ped Protection
Zones. The outputs of Ped Protection Zones will be mapped to inputs in
actuated signal controllers to extend phases and intervals to prevent the
release of conflicting vehicle traffic, and to implement custom logic for
other responses.
e. V2X
i. The system shall support connected vehicle applications and connected
intersection operation per relevant industry standards and guidelines
including CTI 4001, CTI 4501, J2735, J2745, NTCIP 1202, and NTCIP
1218. It shall be capable of generating SDSMs for non-connected road
users per SAE J3224-1.
f. Traffic Counts
i. The system shall count vehicles and VRUs traversing the intersection
using trajectories rather than detection zone actuations. Systems that
require setup or configuration of detection zones specifically for counts
are not compliant with this specification.
ii. The system shall provide textual and graphical user interfaces in the
cloud portal to view counts for two user-specified periods (for side-by-side
comparisons); filter them by maneuver (left, through, right, U-turn, ped x-
ing), class, phase, and approach; and export them to CSV in 15 minute, 1
hour, and 24 hour bins.
iii. The system shall automatically export counts to the MS2 Traffic Count
Database System (TCDS) and provide a user interface in the cloud portal
to view and edit MS2 TCDS API con-figuration data including logon
credentials and signal IDs.

• Pedestrian delay
• Level of service
• Arrivals on green/red
• Purdue phase termination
• Split monitor
• Peak hour, peak hour factor, design hour factor, and directional
factor
ii. The system shall acquire SPM data from trajectories rather than detection
zone actuations. Systems that require setup or configuration of detection
zones specifically for SPMs and those that derive SPMs from high-resolution
data logs of actuations are not compliant with this specification.
iii. The system shall provide textual and graphical user interfaces in the cloud
portal to view SPMs for two user-specified periods (for side-by-side
comparisons); filter them by class; and export them to CSV and PDF.
h. Incident Detection
i. The system shall detect incidents that disrupt the normal flow of traffic,
including but not limited to crashes, road work, and disabled vehicles. It
shall provide user interfaces in the cloud portal to view time-stamped
incident logs and shall deliver incident notifications via email, text, and
phone.
i. Video Clip Management
i. The system shall store 30 days of video in the fusion sensors. It shall
provide user interfaces in the cloud portal to upload clips from user-
specified fusion sensors for user-defined dates and times, play uploaded

i. The system shall detect near-miss events. It shall provide textual and
graphical user inter-faces in the cloud portal to view near-miss events for
user-specified periods and intersections, including a heat map of events
showing their severity and location superimposed on an overhead view of
the intersection. For each near-miss event, the system shall provide post
encroachment time (PET), time to collision (TTC), classes, trajectories,
and a video clip.
k. Optimization
i. The system shall provide real-time, trajectory-based, distributed adaptive
signal control (“Optimization”). Optimization shall be compatible for all
makes and models of actuated signal controllers and transportation field
cabinets. Optimization shall use data from object detection rather than
detection zone actuations so as not to require setup or configuration of
detection zones specifically for Optimization.
34 41 00 - 51 DCR15
ii. Optimization shall support a variety of intersection-level and corridor-level
strategies including balanced delay reduction, progression, crossing
arterial coordination, queue management during oversaturation, transit
prioritization, pedestrian prioritization, maximal throughput, queue
management on freeway off ramps, progression of non-through
movements, preemption recovery, and tightly spaced intersection
management. Multiple strategies shall be capable of being in effect
simultaneously. Cycle lengths shall be optimized and implemented on a
per-Intersection basis so as not to require a common cycle length along
the corridor.
iii. The system shall provide textual and graphical user interfaces in the
cloud portal to monitor, configure, and control Optimization.
l. Red Light Running Analytics
i. The system shall identify vehicles entering intersections on yellow and
red. It shall provide textual and graphical user interfaces in the cloud
portal to view yellow and red light running events for user-specified
periods and intersections. For each yellow and red light running event,
the system shall provide class, maneuver, lane, approach, signal interval
(yellow change, red clearance, or full red), distance from stop line at
yellow, speed, time after yellow, and a video clip.
m. Remote Controller Access
i. The system shall proxy the browser user interfaces of actuated signal
controllers connected to CIUs and display them in the cloud portal. The
proxied browser user interfaces shall support all functionality of the native
browser user interfaces including but not limited to con-troller status

3. Fiber Cable Vaults
a. Fiber cable vaults shall be installed in accordance with the following:
i. Excavation shall comply with the requirements of Section 31 00 00 -
Earthwork.
ii. All openings around conduits shall be sealed and filled with grout to prevent
water and debris from entering the vaults or pull boxes. The grout shall meet
the specifications of the fiber vault manufacturers.
iii. Backfilling around the work shall not be allowed until the concrete or mortar
has set.
iv. Upon acceptance of work, fiber vaults shall be free of debris and ready for
cable installation. All grounding requirements shall be met prior to cable
installation.
v. Fiber vaults shall be adjusted to final grade using risers or rings
manufactured by the fiber vault and pull box manufacturer. Fiber vaults with
traffic bearing lids shall be raised to final grade using ring risers to raise the
cover only.
vi. Fiber vaults shall be installed at the approximate location shown in the
Contract Drawings. Where conflicts arise with the location of the vault and
existing underground utilities, the Contractor shall follow the procedures as
outlined in TSS Section 8-20.3(6).
vii. All existing conduits will need to be open and exposed for access within the
vault. Care shall be taken to identify which conduits have existing cables. All
conduits will extend 2-inches within the vault walls. At the 2-inch mark, the
excess conduit on the existing structure will need to be removed and all
cables exposed.
viii. Once the conduits are located, excavate a hole large enough to install the
fiber vault. The vault shall have a concrete floor as indicated on the Contract
Drawings. The floor shall be installed on 6-inches of crushed surfacing top
course, per TSS Section 9-03.9(3). Ensure that the existing conduits are at a
minimum of 4-inches above the top of the floor. If the existing conduits
contain existing cables, the new vault will need to be bottomless to allow the
existing conduit and cables to be routed into the new vault.
4. Fiber Optic Cable Installation
a. The Contractor shall prepare and submit joint use applications for fiber
attachments to PSE wood poles on behalf of the City of Auburn. Joint use
applications shall be submitted and approved by PSE prior to completing any
fiber and/or riser installations on PSE poles.
b. The Contractor shall include all fiber cutovers and anticipated down time in their
construction schedule. Any change in schedule for impacts to fiber shall be
provided a minimum of two weeks in advance. The Contractor shall meet with
City staff to discuss all cutovers to work out a plan to minimize down time.
c. Fiber optic cables shall be installed in continuous lengths without intermediate
splices throughout the entire project, except at the location(s) specified in the
Plans. The cable installation personnel shall be familiar with the cable
manufacturer’s recommended procedures including but not limited to the
following:
34 41 00 - 127 DCR15
i. Proper attachment to the cable strength elements for pulling during
installation.
ii. Cable tensile limitations and the tension monitoring procedure.
iii. Cable bending radius limitations.
d. The Contractor shall comply with the cable manufacturer’s specifications.
e. To accommodate long continuous installation lengths, bi-directional pulling of the
fiber optic cable is approved and shall be implemented as follows: From the
midpoint, pull the fiber optic cable into the conduit from the shipping reel. When
this portion of the pull is complete, the remainder of the cable must be removed
from the reel to make the inside end available for pulling in the opposite direction.
This is accomplished by hand pulling the cable from the reel and laying into large
figure eight loops on the ground. The purpose of the figure eight pattern is to
avoid cable tangling and kinking. The loops must be laid carefully one upon the
other (to prevent subsequent tangling) and must be in a protected area. The
inside reel end of the cable is then available for installation. In some cases, it
may be necessary to set up the winch at an intermediate cable vault. The
required length of cable is pulled to that point, and brought out of the cable vault
and coiled into a figure eight. The figure eight is then turned over to gain access
to the free cable end which can then be reinserted into the duct system for
installation into the next section.
f. Installation shall involve the placement of the fiber optic cables in a specified
innerduct or conduit as defined in the Drawings. The Contractor shall ensure that
innerducts are secured to prevent movement during the cable installation.
g. Prior to pulling fiber optic cables through existing conduits, the Contractor shall
verify that the conduits are clear of any debris and that the conduits have enough
room to accommodate the new fiber and any existing conductors (where present
and not specified for removal). Where noted on the Drawings, the Contractor
shall remove the existing copper interconnect cable prior to installing the new
fiber optic cable.
h. The pulling eye/sheath termination hardware on the fiber optic cables shall not be
pulled over any sheaves.
i. When power equipment is used to install the fiber optic cables, it must be
designed to be used with fiber optic cable. Low speeds shall be used, not to
exceed 100 feet per minute. The equipment must show the rate of pull, tension
and automatically shut down if any cable pulling parameters are exceeded. The
tensile and bending limitation for fiber optic cables shall not be exceeded under
any circumstances. The use of large diameter wheels, pulling sheaves, and
cable guides shall be used to maintain the appropriate bending radius. Tension
monitoring shall be accomplished using commercial dynamometers or load-cell
instruments.
5. Fiber Optic Patch Cords
a. Fiber optic patch cords shall be installed in each cabinet as noted in the Contract
Drawings.
6. Fiber Optic Cable Splicing
