- Support for up to 16 inputs and outputs allows for detection of multiple phase types (such as traffic and pedestrian phases, signal-state confirmation, etc).
- Detailed event logging enables agency personnel to view system-specific logs or merged logs—allowing for easy evaluation and comparison.
- Dual-card Priority Detector plugs into the same card files as optical systems.
- Ethernet and USB ports on Priority Detector facilitate local and remote configuration, programming, firmware upgrades, and log retrieval.
- Priority Detector is compatible with NEMA, 170/2070, Caltrans, ITS, and custom cabinets.
First Response – Dual 'Optical/RF' Detection
Many agencies find themselves maintaining outdated signal-priority systems due to the expense involved with a full-system replacement. Upgrading from a legacy optical system to an advanced GNSS/RF system had previously meant replacing all vehicle and wayside equipment. This is no longer the case.
The EMTRAC system can detect optical signals from all major optical brands, as well as from the more-advanced EMTRAC GNSS/RF system. This capability enables cities to upgrade selected optical components while leaving other components in place until budgets allow for expanded upgrades.
EMTRAC Priority Detectors support up to 16 inputs, allowing for priority calls to be received for multiple phases from both optical and EMTRAC GNSS systems. Detectors plug into the same input files as optical phase selectors (or may be housed in shelf-mount enclosures in NEMA cabinets). Priority Detectors are capable of connecting to optical sensors while simultaneously connecting to omnidirectional antennas for the RF-based EMTRAC system.
- Cost Effective: Decrease upgrade costs by replacing vehicle and wayside units as budgets allow.
- Expandable: Add new functionality and system components without having to replace installed EMTRAC equipment. Expand the system later to take advantage of advanced features, such as adaptive Transit Signal Priority (TSP) and real-time centralized monitoring (AVL).
- Reliable: Wireless communication is not hampered by adverse weather or urban-canyon conditions, with typical range no less than 3,000 feet.
- Low Maintenance: Reduce or eliminate the need for repeated cleaning of wayside optical components.
