Detection Zone Programming. Place the detection zones by means of a graphical interface using the radar return of vehicles travelling the roadway. On the monitor, superimpose the image of the detection zones on the lanes of traffic. Create the detection zones by using the mouse or pointing device to draw detection zones on the monitor. The detection zones must be capable of being sized, shaped and overlapped to provide optimal road coverage and detection. Save the detector configurations on disk, to download detector configurations to the RDS processor unit, and to retrieve the detector configuration that is currently running in the RDS processor unit. Use the mouse or pointing device to edit previously defined detector configurations so as to fine-tune the detection zone placement size and shape. Once a detection configuration is created, the system must provide a graphic display of the new configuration on a field monitor. If a vehicle occupies a detection zone, the detection zone on the live radar must indicate the presence of a vehicle, thereby verifying proper operation of the detection system.
Detection Zone Programming. Placement of detection zones must be by means of a graphical interface using the video image of the roadway. The monitor must show images of the detection zones superimposed on the video image of traffic while the VIVDS 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, shaped and overlapped to provide optimal road coverage and detection. It must be possible to upload detector configurations to the VIVDS processor unit and to retrieve the detector configuration that is currently running in the VIVDS processor unit. The mouse or keypad must be used to edit previously defined detector configurations so as to fine tune the detection zone placement size and shape. Once a detection configuration has been created, the system must provide a graphic display of the new configuration on its monitor. While this fine-tuning is being done, the detection must continue to operate from the detector configuration that is currently called. When a vehicle occupies a detection zone, the detection zone on the live video must indicate the presence of a vehicle, thereby verifying proper operation of the detection system. With the absence of video, the card must have an LED that will indicate proper operation of the detection zones. Provide detection zones that are 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 if a vehicle traveling any direction other than the one specified for detection occupies the detection zone. Cross-street and wrong way traffic should not cause a detection.
