- Adaptive signal control for dynamic traffic volumes
- Emergency vehicle preemption and pedestrian safety systems
- Integration with Ethernet and detection devices
- Transit signal priority and public transit coordination
- Flashless firmware and OS updates for uninterrupted performance
- Long-term scalability and expandable memory configurations
- Full Build America, Buy America (BABA) compliance
Featured Traffic Signal Controllers
XN-1 Nema TS2 Type 1
Now available with a modern Velocity™ V5 ARM processor for massively increased power and performance. Its open architecture platform organizes and improves traffic signal operations while reducing the amount of equipment in traffic cabinets through multi-application support for things like:
- Managing Ethernet traffic
- Monitoring detection devices
- Integrating with third-party devices
XN-1 Nema TS2 Type 2
An OLED screen improves visibility in all conditions, during the day and at night. Utilizing a Linux-based operating system that meets and exceeds current ATC, NEMA, and NTCIP standards, the XN-2 Controller delivers a robust, scalable platform to meet transportation needs today and tomorrow.
- Fast, reliable intersection control
- Powerful CPU with expandable memory configurations
- Schedule updates or run live
- Install firmware and operating system updates without placing the controller in flash
- Exceeds current ATC standards
- Unrestricted use license for MIBs
- Built and sourced in the USA for full BABA compliance
Enhance Urban Mobility & Public Safety
Our traffic signal systems empower agencies to achieve measurable reductions in congestion, vehicle delays, and intersection collisions. By integrating real-time traffic data and analytics, controllers can adjust signal phases based on actual conditions, improving roadway performance without the need for major infrastructure overhauls.
- Improved public safety and pedestrian protection
- Optimized traffic throughput for arterial and grid networks
- Compliance with federal funding requirements
- Seamless deployment within existing signal networks
- Reduced long-term maintenance costs
Smart City & Connected Infrastructure Ready
Our solutions align with broader smart city initiatives, offering compatibility with vehicle-to-infrastructure (V2I) systems, connected vehicle platforms, and centralized traffic management software. Whether your agency is managing a single corridor or an entire metro area, our controllers provide a future-ready platform for intelligent mobility.
Built for Public Sector Needs
We understand that every city and state has unique regulatory, operational, and procurement requirements. Our controllers are specifically designed for public sector deployment, offering flexible configurations and full documentation to support traffic signal modernization, bid compliance, and grant funding initiatives.
- RFP-ready technical specifications
- Engineering documentation and cut sheets
- On-site and virtual deployment assistance
- Technical training for public agency staff
