If DC power is required for the device submitted, the Contractor is responsible for providingsubmitting a DC power supply submittal with the variable speed systemtraffic sensor cabinet fabrication submittals.
Radar traffic detectors must be interface with Agency’s central Intelligent Devices, Incorporated software interface at no additional cost to Agency.
Radar traffic detectors must:

• 
  Measure 85th percentile speed within +/- 3 mph when there are at least 200 vehicles in one direction in a 15-minute time period
  
• 
  Measure average speed
  
• 
  Detect vehicles by lane
  
• 
  Detect vehicles bi-directionally
  
• 
  Aggregate data over user-defined intervals (minimum interval shall be 20 seconds)
  
• 
  Measure volume with at least 98% accuracy when at least 200 vehicles are measured in one direction in a 15-minute time period
  
• 
  Measure occupancy with at least 95% accuracy
  

The following radar traffic detector is known to meet the project requirements listed above:

• 
  RTMS G4
  

Other radar traffic detectors may be proposed, but they must meet the requirements listed above.

ODOT has central software that is NTCIP 1209 compliant and does not plan on using manufacturer specific software to be able to retrieve the traffic data from the traffic sensor. If the traffic sensor is unable to communicate with ODOT’s central, Intelligent Device’s NTCIP Device Tester will be used to determine the interoperability issue. Contractor shall modify their NTCIP communications if the traffic sensor is determined to not be non-compliant to NTCIP Device Tester.
The Contractor shall submit to the Engineer complete documentation in ASCII versions of the following MIB files in ASN.1 format:
(1) The relevant versions of each official NTCIP standard MIB module referenced by the device functionality.
(2) If the device does not support the full range of any given object within an NTCIP standard MIB module, provide a manufacturer specific version of the official NTCIP standard MIB module with the supported range indicated in ASN.1 format in the SYNTAX field of the OBJECT-TYPE macro. The filename of this file shall be the same as the standard MIN filename with the extension “.man”.
(3) Additionally, ASCII versions of any and all manufacturer specific objects and traps supported by the device in ASN.1 format in a manufacturer specific MIB with accurate meaningful DESCRIPTION fields and supported ranges indicated in the SYNTAX field of the OBJECT-TYPE and/or TRAP-TYPE macros.

(ab) Radar Stop Bar Detector - Contractor shall provide and install radar stop bar detectors as shown on the plans. The radar stop bar detectors shall be designed for queue detection and , ramp metering, travel time prediction, permanent traffic counting applications, and traffic loop replacement applications. Radar stop bar detectors shall meet the following requirements:

Technology: Microwave radar

Frequency: 24 GHz

Lane dDetection zones: 64 (minimum), 3 each direction (minimum)

Detection range: Up to 250100 feet (minimum)
