Roadway Flood Detection and Warning System

ToltHawk’s roadway monitoring solution is designed to improve safety in known flood-prone road segments by providing real-time detection and automated driver warnings. The system uses compact sensing units integrated directly into reflective road markers installed flush with the pavement surface, preserving standard roadway geometry and maintenance practices.

When water levels rise above predefined thresholds, the embedded sensors wirelessly communicate with nearby roadside flashing beacons or warning lights. These lights are automatically activated to alert motorists of hazardous conditions ahead, helping agencies reduce the risk of vehicle incidents, road damage, and emergency response events.

The system operates continuously and does not rely on visibility or manual intervention. It functions in low-light conditions, heavy rain, and overnight hours, making it suitable for rural roads, low-water crossings, underpasses, and other locations with recurring flood risk.

ToltHawk’s approach allows transportation agencies to deploy targeted, low-profile flood monitoring infrastructure without major roadway modifications, while providing actionable, location-specific warnings that enhance public safety and support informed roadway management decisions..
