Radar Vehicle Detection System

The Vendor is required to provide radar vehicle detection system for advance radar, side fire radar, and presence detection (stop bar) radar systems (RVDS) used to detect vehicles on a roadway via processing of radar electromagnetic waves.
- Radar advance detection devices (RADD) functional requirements
• RADD (via interface module) shall provide detection and contact closure to the signal controller for vehicles (including motorcycles) approaching the intersection.
• RADD must continuously provide vehicle detection, tracking and speed of moving vehicles or clusters of vehicles simultaneously approaching an intersection at a range between at least 100 feet to 500 feet from the radar sensor
• RADD system shall be capable of creating a minimum of 3 detection zones in advance of the stop bar that cover up to 5 lanes of approach traffic.
• Zone length will be user definable with-in the detection range.
• Conditional logic to the detection zones that allows contact closure to occur only when logic conditions are satisfied shall be provided.
• Conditional logic programming will allow the user to control when contact closure occurs to the detector rack interface module.
• RADD software shall be capable of applying minimum and maximum speed settings within a detection zone to create a desired speed range for contact closure to the detector channel.
• Vehicles detected within the minimum and maximum speed settings will apply contact closure to the assigned detector channel input in the signal controller.
• RADD must achieve a minimum of 95 percent detection accuracy for vehicles or clusters of vehicles within the detection zone.
• A cluster is defined as vehicles side by side or single file within approximate 1 second spacing.
• Radar graphical user interface (GUI) will indicate detection, show when logic conditions for speed are satisfied and when contact closure to the assigned controller detector channel is applied to the controller.
• The RADD shall be capable of delay timing
• Minimum the user shall be able to program and select delay timing from 0-25 seconds in one/tenth (.1) second increments from the GUI provided with the RVSD system.
• The RADD shall be capable of extension timing as this specification.
• The user shall be able to program and select extension timing from 0-25 seconds in one/tenth (.1) second increments from the GUI provided with the RVSD system.
• The RADD shall be capable of tracking and detecting up to 25 individual vehicles at a time.
