d. Maintenance bypass switch/automatic transfer switch

2. Mode of Operation.

The BBS shall be designed to operate continuously at rated capacity as an on-line, automatic reverse transfer system in the following modes:

a. Normal. The inverter continuously supplies AC power to the critical load. The rectifier converts a utility AC power source to regulated DC power which then serves as the inverter input and, simultaneously, as a float charge input to the storage battery. The BBS provides voltage regulation and power conditioning when using utility power.

b. Emergency. In the event of a utility AC power failure, or over voltage, the inverter shall derive its input from the system battery, therefore providing uninterrupted power to the critical load. This transition shall be accomplished in 65 milliseconds or less. The BBS or external relay shall indicate loss of utility power and energize an external lamp mounted on the BBS cabinet.

c. Recharge. Subsequent to restoration of utility AC power, the rectifier shall automatically reactivate and provide DC power to the inverter, simultaneously recharging the system battery. The automatic transfer switch will provide automatic switching from battery power to utility power. This occurs automatically and without interruption to the critical load, with a 65 millisecond or less re-transfer time.

d. Maintenance Bypass. The BBS system shall be equipped with an external MBS to allow safe and reliable maintenance of the BBS. The maintenance bypass switch shall be equipped to prevent a malfunction feedback to the cabinet or from feeding back to the utility service per UL 1778, Section 48 "Back-feed protection Test".

The upstream back feed voltage from the bypass switch shall be less than 1 volts AC for the protection of the traffic technician.

e. Return to Utility Power, Under voltage. Upon restoration of utility power, the

BBS shall return to the utility power source when the source voltage exceeds 105 volts for more than 30 seconds. Over voltage-The BBS shall return to utility power source when the utility power source has been restored to below 128 volts for more than 30 seconds. The time delay to initiate the return to utility power shall be field programmable from 3-10-30 and 50 seconds. Transition time from BBS back to utility shall be no more than 65 milliseconds.

f. BBS Failure. Upon failure or loss of BBS, the automatic transfer switch will isolate the BBS from the system, and provide power from the utility source (if available). An external alarm will be provided to indicate loss of BBS, or BBS failure.

2. DEFINITIONS

2.1. FEDS Processor Unit. The electronic unit that processes the video image provided by the cameras, generates vehicle detections for defined zones, and collects vehicular data as specified.

2.2. Fish-Eye Camera Assembly. A fixed position fish-eyed IP-camera sensor used to collect the visual image that will be processed for stop-bar detection at the intersection. The camera assembly must consist of an IP-camera, environmental enclosure, sun shield, temperature control mechanism, surge suppression device, and all necessary mounting hardware.

2.3. Advance Camera Assembly. A fixed position IP-camera sensor used to collect the visual image that will be processed for advance detection at the intersection. The camera assembly must consist of an IP-camera, 2 - 9 03-25

OTU

environmental enclosure, sun shield, temperature control mechanism, surge suppression device, and all necessary mounting hardware.

2.4. Power Over Ethernet (POE). The POE is typically considered for powering up FEDS camera assemblies.

The POE can be internal or external to the FEDS processor unit.

2.5. Ethernet Repeater. The passive device allowing runs between POE and camera assemblies to be greater than EIA/TIA 100m standard. These enclosures must be weatherproof (ip66) and receive 8p8c (RJ-45) connectors on each end. The capacitors inside components must allow for the increased transmission lengths of multiple 100m Ethernet cable runs (maximum of two repeaters in-line per run between POE and camera).

2.6. External Switch Assembly. A multiport switch allowing for expandability of a single FEDS processor unit to manage more than two cameras. All components internal to the FEDS processor system must be endorsed in writing by FEDS processor unit manufacturer, for compliance.

2.7. Surge Suppression Device. Modular designed component intended to lessen the surges possible on field communication link between camera and processor. This device is intended to sacrifice itself to preserve more expensive components of the system.

2.8. Field Communications Link. The communications connection between the camera and the FEDS processor unit. The primary communications link medium is typically Ethernet cable.

2.9. FEDS Processor System. One or more detection camera units, and one or more FEDS processor units required to handle the number of camera inputs drawn in the design, along with all peripheral equipment necessary to achieve a functioning detection system.

2.10. Field Setup Computer. A laptop used to set up and monitor the operation of the FEDS processor unit. If required to interface with the FEDS processor unit, the field setup computer with the associated peripherals described in this Special Specification and a video monitor, also described in this Special Specification, must be supplied as part of the FEDS.

2.11. Remote Communications Link. The communications connection between the FEDS processor unit and the Traffic Management Center (typically cellular modem or fiber optic cable).

2.12. Intersection Box. Defined as the internal intersection area, inside of the stop-bars or crosswalks, defining the internal portion of the intersection.

2.13. Detection Zone. The detection zone is a selection of lanes or area, selected through the FEDS processor unit, that when occupied by an automobile, bicycle, or pedestrian, transmits a vehicle detection to the traffic controller or freeway management system.

2.14. Detection Accuracy. The measure of the basic operation of a detection system (shows detection when a vehicle is in the detection zone and shows no detection when there is not a vehicle in the detection zone).

2.15. Lux. The measure of light intensity at which a camera may operate. A unit of illumination equal to 1 lumen per square meter or to the illumination of a surface uniformly 1 m distant from a point source of 1 candle.

2.16. Occlusion. The phenomenon when a vehicle passes through the detection zone but the view from the sensor is obstructed by another vehicle, tree, or alike. This type of occlusion results in the vehicle not being detected by the sensor or when a vehicle in one lane passes through the detection zone of an adjacent lane.

This type of occlusion can result in the same vehicle being counted in more than one lane.

2.17. Glare. The phenomenon when the sun position (or headlights) on the roadway causes a hot-spot on the image from the view of the sensor. This type of condition results in a false vehicle call being placed by the

3 - 9 03-25

OTU

sensor when occurring in the detection zone. This type of false call can result in the poor actuation control of the signal in more than one lane.

2.18. Live Video. Post-processor video viewed at a minimum of 10 frames per second.

2.19. Video Monitoring. Video must be capable of being viewed from a monitor or laptop computer at the cabinet, when connected to the FEDS processor unit. Remote video monitoring capabilities will be obtainable when a provided IP connection from a remote computer to the FEDS processor unit is provided, running the processor’s IP-decoder software.

3. FUNCTIONAL CAPABILITIES

The system software must be able to detect both approaching and departing vehicles in multiple traffic lanes.

A minimum of 16 detector outputs and a minimum of eight inputs per video processor (fish eye counts as four inputs, advance camera counts as one input) module and each module must have a minimum of 16 detection zones. Each zone and output must be user definable through interactive graphics by placing lines and boxes in an image on laptop or monitor. The user must be easily able to redefine previously defined detection zones.

The camera must operate while directly connected to FEDS processor unit. The FEDS must provide real-time vehicle detection (within 200 m of vehicle arrival).

The FEDS processor unit must compensate for minor camera movement (up to 2.5% of the field of view) without falsely detecting vehicles. The system must be able to detect the presence of vehicles in a minimum of 16 unique detection zones within the combined field of view of all cameras. Detection zones must be provided that are sensitive to the direction of vehicle travel. The direction to be detected by each detection zone must be user programmable.

Once the detector configuration has been downloaded or saved into the FEDS processor unit, the video detection and tracking system must operate with the monitoring equipment (monitor and laptop) disconnected or online.

When the monitoring equipment is directly connected to the FEDS processor unit, it must be possible to view vehicle detections in real time as they occur on the field setup computer’s color display. When monitoring equipment is disconnected, the FEDS processor unit must contain indications (light-emitting diode [LED] lights), indicating when a vehicle call is being placed on a phase or detector.

3.1. FEDS Vehicle Detection.

3.1.1. Detection Zone Placement. The video detection system must provide flexible detection zone placement anywhere within the combined field of view of the image sensors. Preferred presence detector configurations are boxes placed across lanes of traffic or in line with lanes of traffic. A FEDS processor must be able to replace one or more conventional VIVDS detectors. In addition, detection zones must have the capability of implementing logical functions, including presence, extension, and delay timing.

3.1.2. Detection Zone Programming. Placement of detection zones must be by means of a graphical interface using the video image of the roadway. The video monitoring software must show images of the detection zones superimposed on the video image of traffic while the FEDS processor is running.

The detection zones must be created by using the mouse or keypad to draw detection zones on the monitor.

The detection zones must be capable of being sized and shaped to provide optimal road coverage and detection. It must be possible to upload detector configurations to the FEDS processor unit and to retrieve the detector configuration that is currently running in the FEDS processor unit.

4 - 9 03-25

OTU

When a vehicle occupies a detection zone, the detection zone on the FEDS display must indicate the presence of a vehicle, thereby verifying proper operation of the detection system. Fail-safe configuration in the absence of video must be user defined but will come default as Max Recall. The processor unit must have an LED indicator confirming proper operation of the camera units and of the detection zones.

Detection zones must be configurable to provide calls sensitive to the direction of vehicle travel. The direction to be detected by each detection zone must be user programmable. The vehicle detection zone should not activate a call to the controller if a vehicle traveling any direction other than the one specified for detection occupies the detection zone. Cross-street and wrong way traffic must not cause a false detection.

3.1.3. Design Field of View. The video detection system must reliably detect vehicle presence in the design field of view. The design field of view must be defined as the sensor view when the image sensor is mounted 27 ft or higher above the roadway. Within this design field of view, the FEDS processor unit must be capable of setting up a detection zone for each directional approach.

3.1.3.1. Fish Eye Camera. The camera must be placed inside the intersection box (inside of all stop-bars) to the edge of the nearest vehicle travel lane. A single camera, placed at the proper mounting height with the proper lens, must be able to monitor and detect a minimum of 10 different approach vectors.

3.1.3.2. Advance Camera. The camera must be placed outside the intersection box (typically top luminaire or on mast-arm extension) to view vehicles approaching greater than 200 ft back of the stop-bar. A single camera, placed at the proper mounting height with the proper lens, must be able to monitor and detect a minimum of four lanes wide, at a distance of 300 ft behind its mounting location.

3.1.4. Detection Performance. Detection accuracy of the video detection system must be comparable to properly operating inductive loops. Detection accuracy must include the presence of any vehicle in the defined detection zone regardless of the lane the vehicle is occupying. Occlusion produced by vehicles in the same or adjacent lanes must not be considered a failure of the FEDS processor unit, but a limitation of the camera placement. Detection accuracy (a minimum of 95%) must be enforced for the stop-bar views included in the design field of view on a lane-by-lane and time period basis. When specified on the plans, furnish up to 24 continuous hours of recorded video of all installed intersection cameras within the 30-day test period for verification of proper camera placement, field of view, detection zone placement, processor setup, and operation. Test period must allow for initial 24-hr processor “learning cycle,” allowing for the camera to self-evaluate current setup orientation. The video from each system must show vehicle detections for all zones.

3.1.5. Equipment Failure. If either the cameras or FEDS processor unit fail, the result must put in a constant vehicle detection on affected detection zones. This option must be programmable in the processor unit and the traffic signal controller.

3.2. Operation from Central Control. The central control must transmit and receive all information needed for detector setup, vehicle detection monitoring, and intersection traffic flow monitoring at a display rate of five frames per second or greater for high-speed connections (as specified on the plans) and interrogate all required stored data. The remote communications link between the FEDS processor unit and central control may be cellular modem (third party provided) or dedicated twisted wire pair communications cable that may be accompanied with coaxial cable or fiber optic cable, as shown on the plans. Communications with the central control must not interfere with the on-street detection of the FEDS processor. Quality of the video at five frames per second rate must be such that the view with the traffic flow is clear and operation of the detection system discernable.

3.3. Data Collection and Reporting. When called for on the plans, the FEDS should be capable of providing count data, access to real-time data, and system and user-defined alerts. The ability to provide this information should be retained for the life of the FEDS once purchased if called for by the plans. The count data should be accessible directly from the processor or from a remote computer with a network connection.

The count data must include at least the following type of reports.
