not certify dedication of the traffic signal until the private entity
contracting the work has completed all necessary roadway improvements
as part of the land development agreement process. If the roadway
is a PennDOT roadway, PennDOT approval is needed prior to Township
approval. The traffic signal installation is considered a roadway
improvement, and as such, shall not be accepted by the Township until
all roadway improvements are certified complete by the Township Engineer
and accepted for final dedication by the Township.
(e)
If the traffic signal installation is on a PennDOT roadway,
certification of all appropriate agreements, escrowed funds, and approvals
with and from PennDOT will be required. The Township will consider
accepting for final dedication.
(2)
Until final dedication is granted to the contractor, the contractor
is responsible for commencing repairs by repairing or replacing malfunctioning
parts or equipment or faulty workmanship, regardless of the cause,
after having been notified by the Township. In addition, during this
time period the contractor must guarantee the satisfactory in-service
operation of mechanical and electrical equipment, related components,
signing (if applicable), pavement markings (if applicable), and the
controller assembly, regardless of the cause for unsatisfactory operation.
During this time, any deteriorating pavement markings must be repaired.

There will be one six-to-eight-port POE+ hardened network switch,
with power supply, installed in the enclosure which will serve as
the common connection point for the server, cameras and LAN link on
the Comcast router. This switch will provide the necessary power for
all cameras.

surveillance. This camera is a high megapixel (5MP or higher) and
is installed on the traffic pole that will provide the widest view
of the intersection. The cameras will have day/night functionality
which will switch from color to black-and-white when the light level
drops below a predefined threshold.
(h)
The goal of the cameras mounted on the poles above the lanes
is to provide an unobstructed telephoto view of the back of the vehicle
as it travels through the intersection. The lane camera will be a
2MP varifocal model. At night, the infrared illuminator will provide
the necessary IR light required to view the license plate. One camera
per lane (both directions) of the intersection is required.
(11)
Conduit runs will be sized for future use. All main street crossings
will, at a minimum, be two- to three-inch conduits. Controllers should
be located at the intersection of conduit runs, and not at the end
of a conduit loop. Each controller foundation, or pole foundation
if the controller is pole-mounted, will, at a minimum, have the equivalent
of two- to three-inch conduits entering it from an adjacent junction
box. All loops will terminate in junction boxes, and there will be
at least one JB 27 junction box on each corner.
(12)
Street lighting circuits will be installed in a separate two-inch
conduit system specifically for that purpose and will be protected
by circuit breakers that are also separate from the traffic signal
system.
(13)
For intersections along Routes 452, 322, and Chichester Avenue:
(a)
Controller assembly and cabinet. All controller assemblies shall
be NEMA TS-2, Type 1 and shall be equipped with an eight-phase load
bay panel (sixteen-position) capable of providing the required sequence
of operation.
[1]
An Econolite ASC/3 controller unit and/or an Econolite ASC/2M-1000
master controller unit with closed loop system capabilities and controller
key shall be provided.
[2]
A ComNet CNGE2FE16MS ethernet switch (or approved equal) shall
be provided for all controller assemblies. If the intersection will
not be connected to the Econolite Centracs system, the ethernet switch
must be provided to the Township for future connection, and external
modems shall be utilized for communications through the closed loop
system.
(b)
InSync adaptive control.
[1]
The InSync adaptive equipment as manufactured by Rhythm Engineering
shall include InSync processors, equipment panels and power supply,
RG cable, ethernet patch cables, monitors/keyboards, video cameras
and enclosures and all necessary cables connectors, brackets and mounting
hardware. The adaptive signal control system shall be installed in
the controller assembly as recommended by the manufacturer and as
directed by a Rhythm Engineering representative. Connect the InSync
processor to the ethernet switch, install InSync's detector input
connection type and wire the RG return cable.
[2]
Regarding the installation of the video cameras:
[a]
Provide ethernet cable: environmentally hardened,
outdoor-rated 350 MHz Category 5e cable. The cable is required to
be riser rated, 24 AWG solid copper, have Polyolefin insulation, UV
and oil-resistant PVC jacket. Pair 1 to be blue, white/blue, Pair
2 to be orange, white/orange, Pair 3 to be green, white/green and
Pair 4 to be brown, white/brown. The operating temperature is required
to be from - 40° C. to 70° C. The cable will conform to the
following standards: ISO/IEC 11801 Category 5e, NEMA WC 63, and ANSI/TIA/EIA
568-B.2 Category 5e. The cable is required to be without splices or
joints for a single run. Obtain instructions from the manufacturer
about alternate architecture when length of a single run of CAT 5e
cable exceeds 320 feet.
[b]
Provide RJ-45 plug connectors to be used at both
the camera and cabinet ends. Category 5e cable, RJ-45 connectors and
crimping tool requires approval from Rhythm Engineering. Follow the
manufacturer's instructions to insure proper connection of equipment.
[c]
Provide 14 AWG three conductor power cable meeting
the requirements of IMSA specification 20-1.
[d]
Existing vehicle detection at the project intersections
must be maintained until the InSync adaptive system is activated.
[e]
Mount video camera(s) as directed by the factory-certified
representative using mounting brackets to obtain manufacturer recommended
installation location. Provide mounting bracket detail to Engineer
for approval prior to installation. Connect ethernet cable and power
cable in accordance with manufacturer's requirements from each
camera back to the controller assembly.
[f]
Adjust camera(s) as necessary during the system
integration as directed by a Rhythm Engineering representative.
(c)
Vehicle detection.
[1]
Furnish and install video vehicle detection for all approaches
following the manufacturer's specification, in place of standard
in-pavement inductance loop detectors, unless otherwise approved,
in writing, by the Township Public Works Department and Township Engineer.
For video detection, the Autoscope Solo Terra vehicle detection system
shall be utilized, meeting the following specifications:
[a]
EasyLink connectivity for IP-addressable broadband
communications and web server interface for easy setup.
[b]
Streaming digital MPEG-4 video output.
[c]
Vehicle detection, traffic data measurement, speed,
and incident detection.
[d]
Integrated color camera, zoom lens, and dual-core
processor for advanced image processing.
[e]
22x continuous focus lens.
[f]
Image sensor and processor sealed in waterproof
and dust-tight NEMA 4 housing with a thermostatically controlled faceplate
heater.
[g]
EasyLink (broadband communications (up to five
Mb/sec) with RJ-45 connection from required terra interface panel
(TIP).
[h]
Three-year warranty.
[2]
The video detection system shall be installed and calibrated
in accordance with the manufacturer specifications. PennDOT, the Township
Public Works Department, and the Township Engineer must approve the
detector layout and operation.
[3]
LEDs. All vehicular and pedestrian signal heads shall be LED
(light-emitting diode) as manufactured by GE Lumination (formerly
GELcore) and shall meet all current ITE specifications and requirements.
The modules will carry a five-year manufacturer's replacement
warranty for materials and workmanship and light degradation that
begins at the date of delivery. If an LED fails, the supplier will
provide a new replacement LED. Street signs should be LED per PennDOT
standards when applicable.
