This work shall consist of furnishing and installing system hardware that consist of three
components:
A. Two (2) 360 degree view camera detection cameras.
B. A stand-alone video detection processing unit for communication with two 360 degree view
camera. The processing unit shall include an internal pedestrian detection module. The realtime performance shall be observed by viewing the video output from the sensor with overlaid
detection zones that indicate the current detection state (on/off). The sensors shall detect both
pedestrians and vehicles.
The video detection camera shall communicate to a stand-alone video detection unit via a
burial grade Cat5e cable via a software application using the industry standard TCP/IP
network protocol. The video detection camera shall be powered through industry standard
Power over Ethernet (PoE). The video detection unit shall be capable to be programmed
with a static IP address and have two built-in, Ethernet ports and shall be addressable with
no plug in devices or converters required. The stand-alone video detection unit shall
provide standard MPEG-4, motion J-PEG or H.264 streaming digital video. Achievable
frame rates shall provide a minimum of 5 frames per second or higher as a function of video
quality and available bandwidth.
The stand-alone video detection unit shall communicate directly with video detection
cameras providing up to thirty-two (32) inputs and sixty-four (64) outputs or a 170 input file
rack providing up to sixteen (16) contact closure inputs and twenty-four (24) contact closure
outputs to a traffic signal controller. The stand-alone video detection unit shall be equipped
with two serial connections to allow for input/output to a TS-1 or 170/2070 cabinet and a
SDLC port to allow connection to a TS-2 cabinet. A TS-1/170/2070 cabinet harness shall be
available and shall include a input and output cable for installation in TS-1, 170 or 2070

A. Video Detection System Software
The stand-alone video detection unit shall have embedded software to incorporate
multiple applications that perform a variety of diagnostic, installation, fault tolerant
operations, data communications and storage, digital video streaming, and vehicle
detection processing. The detection shall be reliable, consistent, and perform under all
weather, lighting, and traffic congestion levels. An embedded web server shall permit
standard internet browsers to connect and view video streaming services. The software
shall have the ability to mask areas or objects in the field of view that will allow the video
detection unit to ignore areas that are not within the travel way or occlude areas within
the travel way. This feature will increase available processing power for real time
detection and ensure that vehicles remain detected when occluded by objects within the
field of view.
The software shall provide the following applications that and shall execute under
Microsoft Windows 2000, XP or 7. Available applications shall include:


media.
Provide fault-tolerant, real-time TCP/IP communications to/from all devices and
client applications with full logging capability for systems integration.
B. Video Detection Camera
The video detection camera shall produce a useable video image of the bodies of
vehicles. The minimum range of scene luminance over which the camera shall produce
a useable video image shall be the minimum range from nighttime to daytime, but not
less than the range 1.0 lux to 10,000 lux.
The camera shall use a CMOS sensing element and shall output color video with
resolution of not less than 1920 lines horizontal.
The video detection software shall control the exposure and gain of the camera(s). The
wide-angle camera(s) shall not need adjustment to suit the site geometry. The
horizontal field of view shall be 360 degrees. A 360 degree camera shall be capable of
providing detection coverage of all approaches of an average size intersection. Two
wide-angle cameras shall provide detection coverage on large intersections. The
camera shall be housed in a weather-tight sealed enclosure. The housing on the 360
degree camera shall be field rotatable to allow proper alignment between the camera
and the traveled road surface. The camera enclosure shall be equipped with an
integrated sunshield. The sunshield shall include a provision for water diversion to
prevent water from flowing in the camera's field of view. The camera enclosure shall
include a thermostatically controlled heater to assure proper operation of the lens

shutter at low temperatures and prevent moisture condensation and ice buildup on the
optical faceplate of the enclosure. When mounted outdoors in the enclosure, the
camera shall operate satisfactorily in a temperature range from -35 °C to +74 °C and a
humidity range from 0% RH to 100% RH. The camera shall be powered via Power over
Ethernet (PoE) from the stand-alone video detection unit. Power consumption shall be
55 watts or less under normal conditions. The camera shall provide reliable detection
within the height to distance ratio of 10:100. The camera enclosure shall be equipped
with weather-tight cable connections. Video and power shall be transmitted via the
Cat5e burial grade cable and connected within the same connector to the stand-alone
video detection unit.
C. Power
The video detection cameras shall be powered via Power over Ethernet (PoE) from the
stand-alone video detection unit. Power consumption shall be 55 watts or less under
normal conditions.110/220 VAC, 50/60Hz.
D. Detection Zone Programming
Placement of detection zones shall be by means of a laptop with a Windows XP or 7
operating system or with a monitor and a mouse. The laptop or monitor shall be able to
show the detection zones superimposed on images of traffic scenes.
The detection zones shall be created by using a laptop or mouse and monitor to draw
detection zones. Using the mouse and monitor it shall be possible to place, size, and
orient detection zones to provide optimal road coverage for vehicle detection. It shall be
possible to download detector configurations from the laptop to the stand-alone video
detection unit or to retrieve the configuration that is currently operating the intersection,
and to back up detector configurations by saving them to the laptop or other removable
storage media.
It shall be possible to edit previously defined detector configurations to permit
adjustment of the detection zone size and placement, to add detectors for additional
traffic applications, or to reprogram the video detection unit for different traffic
applications or changes in installation site geometry or traffic rerouting. The video
detection unit shall store previously loaded configurations on board and shall be able to
revert to older programming when the command is sent to the unit.
E. Detection
The video detection system shall reliably detect vehicle passage and presence in the
camera field of view when the video detection camera(s) is mounted 30 feet (10 m) or
higher above the roadway and as close to the center of the intersection as possible or
when the camera is adjacent (within 15 feet) to the edge of the nearest vehicle travel
lane. If there are obstructions within the field of view the stand alone video detection unit
shall be equipped with a software function that allows for an object mask to be drawn so
vehicles calls are not placed by the obstruction and vehicles are still detected. The
preferred video detection camera orientation shall be to view approaching traffic since
there are more high contrast features on vehicles as viewed from the front rather than
the rear. The video detection camera placed at a mounting height that minimizes vehicle
image occlusion shall be able to detect at least five (5) traffic lanes on each approach.
Mounting heights as low as 24 feet shall be possible and provide reliable vehicle
detection, vehicle passage and presence within the camera field of view for average size
Page 3 of 4
intersections provided the camera(s) have a reliable head-on view of all approaches.
Pedestrian detection shall also be accurate and reliable when mounted in this
configuration.
F. Data Collection
A properly installed system shall accurately count vehicles with at least 95% accuracy
under normal operating conditions (day and night). The system shall collect data per
direction, per detection zone or phase number.
A properly installed system shall accurately measure average speed of multiple vehicles
with at least 95% accuracy under all operating conditions for approaching and receding
traffic.
A properly installed system shall accurately classify vehicles. Vehicle collection shall be
accurate and programmable by the user to bin data into three different data categories.
All collected data shall be able to be collected remotely or on site via USB or other
storage media. All collected data shall be output to a .csv file for user manipulation.
Video recording shall be accomplished with the connection of a portable external USB
hard drive connection to either of the USB ports on the video detection unit. The video
shall be recorded only when the external hard drive is connected. The amount of video
recorded shall be limited only to the size of the storage device. The laptop software shall
provide the interface to playback the video to analyze operations or to collect turning
movement information.
