Across the United States, thousands of signalized intersections are operating on legacy infrastructure. Cabinets installed decades ago, outdated detection systems, and aging hardware often struggle to meet today’s traffic volumes, pedestrian demands, and data reporting requirements.
For state DOTs and municipalities, full intersection reconstruction is costly, disruptive, and often unnecessary.
A smarter path forward focuses on strategic modernization.
At Blackstar Diversified Enterprises ®, we work with agencies to upgrade intersections through targeted integration of:
• AI-driven vehicle detection platforms
• Modern 170/2070 cabinet systems
• Radar-based speed awareness technology
• High-visibility pedestrian safety enhancements
• Modular traffic signal hardware and mast arm components
Rather than replacing entire intersections, we assess what can be retained and what must be upgraded.
Legacy video detection systems frequently experience missed calls, weather-related interference, and calibration drift. Modern radar + vision fusion platforms — such as AI mobility systems deployed in select U.S. corridors — provide significantly more stable detection while mounting directly to existing mast arms.
This approach minimizes trenching and preserves existing signal controller infrastructure.
Targeted deployment of:
• Rectangular Rapid Flashing Beacons (RRFBs)
• Radar speed feedback signs
• Audible pushbuttons
• School zone safety systems
can significantly improve awareness without redesigning entire corridors.
Modernization is not about replacing everything.
It is about engineering compatibility between legacy infrastructure and emerging intelligent systems.
When executed correctly, agencies achieve:
• Improved detection reliability
• Reduced maintenance callbacks
• Enhanced pedestrian visibility
• Corridor-level data insight
• Future-ready infrastructure
Without tearing up the intersection.
Blackstar Diversified Enterprises ® is a certified electrical systems integrator delivering custom-engineered traffic control systems and power distribution solutions across the Continental United States and South America.
