Phoenix Technical Specifications

Features

  • Count 1 to 16 lanes
    • Count methods include direction, lane subtraction and normal
  • Classify 1 to 8 lanes
    • Possible sensor arrangements per lane for classification: Two Axle sensors
      • Two presence sensor
      • Two axle sensors and one presence sensor
      • Two presence sensors and one axle sensor

  • Record interval lengths from one minute to 24 hours
    • Phoenix can be programmed to change the length of record interval up to five times during the day.  This allows for closer inspection of rush hour traffic patterns if needed.

  • Two modes of count (1 to 16 lanes)
    • Time Interval Count Mode:  The traditional method of time interval counting using the field unit to collect and sort count data by user selectable time intervals. Count methods using two axle sensors per lane (road tube or piezo) include direction and lane subtraction.
    • Time Stamped Sensor Event:  Unit stores in its memory the sensor activation with a time stamp accurate to 1/10695 of a second.  This recorded sensor data is later fed into your PC computer that processes the data using the software.
    • Three modes of classification (1 to 8 lanes)
    • Binning:  User can define 30 speed, 30 axle, 30 headway and 30 gap bins.  Default FHWA 13 bin scheme F, European scheme or your custom scheme on can be used.  Matrix classification = speed by axle, and/or speed by length.
    • Per-Vehicle Data: Classifier stores in memory for each vehicle: Time stamp to 1/100 of a second, speed to 1/100mph or kph, number of axles, and spacing between axles.
    • Time Stamped Sensor Event: Unit stores in its memory the sensor actuations with a time stamp accurate to 1/10695 of a second.  This recorded sensor data is later fed into your PC computer that processes the data using the software.
  • Memory
    • The Phoenix comes standard with 128K of counter memory Expandable up to 1MB. File storage can be expanded beyond 1MB using the optional TAM card (cards sizes from 256K to 16MB).
    • 16-Key watertight keyboard and LCD display
    • Complete alphabet and numbers keyboard. Default includes a two-line, 32-character LCD display with and option of a four line, 64-character display.

  • Sensors available
    • 2 or 4 road tube air switches (32 counts per second)
    • 4 to 16 multiplexing presence loop detectors with optional optical isolated outputs
    • 4 or 8 remote contact closures or open collector to external inputs
    • 4 or 8 piezo electric or piezo resistive sensor inputs (adjustable sensitivity compatible with all brands of standard piezos or resistive sensors)

  • Lane Test and Monitoring:
    • All lanes can be monitored, sensor activation tested, and configurations, spacing and IDs verified without interference of data collections. This can be accomplished either from the display or a PC connection (direct or via modem)
  • Data Collection:
    • PC computer via modem
    • PC desktop/laptop direct connection (RS232)
    • TAM (Take Away Memory) card
  • Files:
    • Up to 99 individual site files can be stored in memory. At your option the files can be set to replace older files or counter can stop collecting new data when memory is full
