The IRD signal preemption system uses WIM technology to detect runaway trucks on a steep grade which leads into a signalized intersection. If a runaway situation is detected, the signal controller is triggered to provide a green light as the vehicle approaches the intersection.

• Detects runaway vehicles before they reach intersections
• Avoid potentially catastrophic accidents
• Triggers to provide or extend a green light
• Reduces property damage, injury
• Saves lives
