QTC Intelligent Traffic Signal Controller:

Overview

  • Capacity: The HADRON controller is fully compatible with the latest SCATS ®. Designed to control up to 32 Signal Groups, it also has up to 48 integrated loop detector channels and up to 48 external inputs. It can be easily interfaced to video detection systems. Flexible to any type input device.
  • Standards: Fully compliant to Specification TSC/4 from Roads and Traffic Authority (RTA) of NSW, Australian and International Standards.
  • Multiple Processors: Providing dual conflict monitoring for additional safety each module is controlled by its own microprocessor.

Logic Rack Sizes:

  • Multiple sizes are available ranging from a little as 4SG all the way up to 32SG, in increments of 4SG.
  • From 16 up to 48 loop detectors plus from 16 up to 48 external inputs.

Traffic Control:

  • The HADRON Traffic Controller is designed to be compatible with the latest SCATS ® generations.
  • New releases can be upgraded on site.

 

Ramp Metering:

  • Full application for Ramp Metering can be achieve with the HADRON Traffic Controller.
  • Ramp Metering is based on the data collection using loop detectors.

Road Site Processor:

  1. Traffic Data Collection
  • Speed
  • Volume
  1. Incident Detection.

Lane Controller:

  • All lane changes are protected by conflict matrix
