Clearance Time Extender
Adjusts the red clearance intervals to help ensure slow moving vehicles clear the work zone before allowing opposing green indications.
Adjusts Red Clearance Intervals in Real-Time
The Clearance Time Extension System increases safety in the work zone by detecting slow moving vehicles and extending the red clearance interval accordingly. If traffic does not clear the work zone within the programmed red clearance time, additional time will be added to allow the slow moving vehicle safe passage out of the work zone.
How It Works
Detection zones are established using non-invasive sensors to detect slow moving vehicles and adjust red clearance times accordingly.
The quanity and length of these detection zones can be adjusted based on application requirements.
