QTC Intelligent Traffic Signal Controller

Description

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

2. Incident Detection.

Lane Controller:

• All lane changes are protected by conflict matrix
• Lamp Monitoring for enhanced safety.

Safety and Dependability:

1. Monitored MTBF >80,000 hours
2. Conflict Monitoring

• Conflict checking BEFORE Lights displayed
• Lamp Drive vs Lamp Status verification
• Conflict checking of the Lights displayed
• Last RED detection
• Independent (secondary) Conflict Monitoring

3. Lamp Monitoring

• Will operate with most lantern types automatically
• Lamp failure monitoring (all lantern types)
• Reports REAL power

4. SCATS ® communications options

• Protocols supported (user field configurable)
  • Original
  • HDLC
• Leased Line
• Dialup line
• ADSL (IP based)
• TCP/IP (IP based communication options support all protocols)
