Quantum HYBRID combines multiple sensor technologies (loops, piezos, LiDAR) affording system designers greater flexibility in meeting customer specifications. The first hybrid installation was completed in 2021 on the Ohio Turnpike.
Quantum HYBRID provides a safe migration path from axle based classification to overhead shape based classification systems with fully quantifiable revenue risk.
≥99.96 detection and up to 99.8% axle classification for a LiDAR/piezo hybrid solution
Shape based classification accuracy depends on class table requirements
Quantum HYBRID Features
- Dual technology redundant designs
- Axle classification (single and dual) with minimal in-pavement installation
- Plain axle, FHWA with dual tyres*
- Provides a safe migration path from axle based classification to overhead shape based classification systems with fully quantifiable revenue risk
- Dual gantry, with single gantry coming
- Reversible lanes (future)
- Operates in all weather conditions
Supported lane types
- Single lane
- Express lane
- Multi-lane
Common Features
- Width, length, roof height, maximum height, speed
- Lateral location in lane (better camera trigger decisions)
- Accurate front and rear trigger messages**
- Wrong way indication
- Over height immediate alarms
- Axle count, location, weight
- Correlated tag data
- Vehicle start and end times
- Unique ID, lane ID, class
- Host integration simplified with virtualisation technology
Quantum HYBRID projects underway
OTIC – 296 lanes to be installed starting in 2022
OTIC is a loop based system, but uses LiDAR for roof and maximum height and as a backup system should the loops enter a degraded state.
