The vendor is required to provide for a video imaging vehicle detection system (VIVDS) that monitors and provides vehicle stop line detection at a roadway intersection via processing of video images and provides detector outputs to a traffic controller or similar device.
• A VIVDS configuration for a single intersection will consist of sufficient cameras, the field communications link, VIVDS card rack or shelf mounted processor system, and all associated equipment required to setup and operate in a field environment including a video monitor, mouse and set-up software with interface cable (if required), connectors and camera mounting hardware.
• The system is composed of these principal items: the camera(s), the field communications link between the camera and the VIVDS processor unit, and the VIVDS processor unit along with a pc if required, video monitor or associated equipment required to setup the VIVDS and if required, central control software to communicate to the VIVDS processor.
- Functional capabilities
• The system software must be able to detect either approaching or departing vehicles in multiple traffic lanes.
• Each zone and output must be user definable through interactive graphics by placing lines and/or boxes in an image on a video or VGA monitor.
• The VIVDS processor unit must compensate for minor camera movement (up to 2% of the field of view at 400 foot) without falsely detecting vehicles.
• The camera movement must be measured on the unprocessed video input to the VIVDS processor unit.
• The camera must operate while directly connected to VIVDS processor unit.
• The monitoring equipment is directly connected to the VIVDS processor unit, it must be possible to view vehicle detections in real time as they occur on the field setup computer's color VGA display or the video monitor.
• Once the detector configuration has been downloaded or saved into the VIVDS processor unit, the video detection system must operate with the monitoring equipment (monitor and/or laptop) disconnected or on-line.
• For systems that utilize video processor module card(s) a minimum of 4 detector outputs per module is required and each module card must have a minimum of 24 detection zones.
• For systems that utilize a shelf mounted processor that connects directly to the port 1 communication cable (SDLC) the processor must be capable of providing up to 64 detector outputs in a national electrical manufacturer association (NEMA) ts2 cabinet.
• The VIVDS must provide real time vehicle detection (within a maximum of 700 milliseconds (MS) of vehicle arrival).
• The VIVDS processor unit must be capable of simultaneously processing information from various video sources, including video players and either cctv or CMOS video image sensors
• The system must be able to detect the presence of vehicles in a minimum of 12 detection zones within the combined field of view of all cameras (a minimum of 12 detection zones per camera input to the VIVDS processor unit).
- VIVDS processor unit
• Cabinet mounting - the VIVDS processor unit must be mountable in a NEMA ts2 detector rack or be a shelf mounted unit not to exceed 14 inch x 12 inch x 5.5 inch (w x d x h).
• VIVDS processor unit - environmental requirements:
o The VIVDS processor unit shall be designed to operate reliably in the adverse environment found in the typical roadside traffic cabinet.
o Operating temperature shall be from –34 (-30 f) to +74 (+165 f) degrees c at 0 percent to 95 percent relative humidity, non-condensing.
• VIVDS processor unit – electrical
o VIVDS processor units that utilize the detector rack must operate at 12v or 24v dc. shelf mounted units must operate within a range of 89v to 135v ac, 60 HZ single phase.
o Power to the VIVDS must be from the transient protected side of the ac power distribution system in the traffic control cabinet in which the VIVDS is installed.
o A connector on the front of the VIVDS processor unit shall be used for serial communications.
o The VIVDS processor unit shall be equipped with rs-170 (monochrome), rs-170a (color) composite video or ethernet inputs, so that signals from image sensors, IP based video or other synchronous or asynchronous video sources can be processed in real-time.
o Video outputs from the processor unit shall be capable of corresponding to any one of the video inputs, as selected remotely via an external graphical user interface on a laptop computer or front panel switch on the processor/ interface module.
o Multiple video outputs requiring external cable connections to create a combined single video output shall not be acceptable.
• Camera assembly
a. The cameras must be approved for use with the VIVDS processor unit by the supplier of the VIVDS.
• Images must be produced with a charge coupled device (CCD) or digital CMOS sensing element with horizontal resolution of at least 480 lines for black and white or 470 lines for color and vertical resolution of at least 350 lines for black and white or color. 
• Images must be output as a video signal conforming to rs170 or IP based video signal.
• Useable video and resolvable features in the video image shall be produced when those features have luminance levels as low as 0.1 lux for black and white or as low as 1.0 lux for color for night use.
• Useable video and resolvable features in the video image shall be produced when those features have luminance levels as high as 10,000 lux during the day.
• The camera shall include an electronic shutter or auto-iris control based upon average scene luminance and shall be equipped with an electronic shutter or auto-iris lens with variable focal length and variable focus that can be adjusted without opening up the camera housing to suit the site geometry.
• The variable focal length shall be adjustable from 6 mm to 34 mm.
b. The camera and lens assembly shall be housed in an environmental enclosure that provides the following capabilities:
• The enclosure shall allow the camera to operate satisfactorily over an ambient temperature range from -34 c (-30 f) to +60 c (+140 f) while exposed to precipitation as well as direct sunlight.
• The enclosure shall allow the camera horizon to be rotated in the field during installation.
• The enclosure must include a provision at the rear of the enclosure for connection of power and video signal cables fabricated at the factory.
• Input power to the environmental enclosure must be nominally 115v ac 60 HZ or power over ethernet (POE) for IP based systems.
• The video output of the cameras shall be isolated from earth ground. 
• All video connections for the cameras to the video interface panel shall also be isolated from earth ground.
