TIME CLOCK

The programmability of the time clock provides traffic engineers with the ability to schedule system activation during specific timeframes.

  • Operated via PC or web-enabled devices
  • Ability to schedule activations up to two years in advance
Time Clock programming schedules system activation times

RADAR DETECTION

Radar sensors are mounted on the first system pole to trigger the system to activate based on predetermined criteria:

  • Vehicle Activated - Triggers system activation when vehicle approaches curve
  • Speed Activated - Triggers system activation when vehicle exceeds predetermined speed threshold and can adjust speeds based on vehicle classification
  • Weather Smart Activated - Triggers system activation when unfavorable weather conditions are present based on predetermined, adjustable speed threshold
Radar detection activates the system to warn drivers of dangerous situation
