What Makes Currux Gen 3 Plus a Game-Changer
Traffic agencies do not always need a completely new workflow. Often, they need a cabinet-ready AI edge server that fits existing operations, improves field reliability, and supports the next phase of Smart City ITS deployment. Currux Vision Gen 3 Plus stands out by building on the familiar Gen 3 platform while adding practical improvements that […]
BACK TO SCHOOL = BACK TO SPEED MANAGEMENT
Every August and September, the transportation environment around schools changes almost overnight. School buses return. Parent drop-off queues grow. Students are walking, biking, and crossing streets during the same morning window when commuters are trying to get to work. Drivers who spent the summer traveling through relatively quiet school zones suddenly encounter a very different […]
Why Cabinet Test Displays Reduce Field Troubleshooting
Traffic signal cabinets do not always fail in obvious ways. For agency teams, a clear cabinet testing display can make it easier to understand what is happening inside the cabinet before a technician makes a field visit. Home Turning Cabinet Activity Into Something Technicians Can See Traffic cabinets manage a lot of activity at once, […]
How Cabinet Testing Displays Support Texas Diamond Interchange Operations
Texas Diamond Interchanges ask a lot of signal cabinet teams. With multiple movements, overlaps, and ramp coordination points operating in a tight footprint, agencies need a clear way to verify cabinet behavior before equipment is placed into service. Texas Diamond Interchanges Depend on Precise Signal Coordination A Texas diamond interchange is a signalized interchange layout […]
What Happens to a Traffic Signal Cabinet During a Power Outage?
When the power goes out, a traffic signal cabinet becomes one of the most important pieces of infrastructure at the intersection. What happens inside that cabinet can determine whether traffic continues moving safely, shifts into flash, or requires an urgent field response. The Cabinet Protects the Intersection’s Core Operations A traffic signal cabinet houses the […]
How Connected Vehicle Technology Can Strengthen Preemption and Priority
Connected vehicle technology is helping agencies make preemption and priority more coordinated, more visible, and more reliable. For cities, counties, and DOTs, the goal is not just to move one vehicle through a green light. It is to help emergency responders travel more safely, keep buses on schedule, improve corridor performance, and give traffic teams […]
How Agencies Can Reduce Queue Spillback at Busy Interchanges
Queue spillback can turn one crowded ramp into a corridor-wide challenge. At busy interchanges, a few missed signal cycles can quickly create backups that block through lanes, slow emergency response, and frustrate drivers who are simply trying to make predictable trips. For cities, counties, and DOTs, reducing queue spillback is not just about moving more […]
PLANNING AN ATTAIN GRANT? HERE’S WHAT MAKES A COMPETITIVE APPLICATION
With $120 million in available funding, awards of up to $12 million per project, and approximately 20 agencies expected to receive funding, now is the time to evaluate your project and prepare a competitive application. Please note that the program includes a cost-sharing (matching) requirement. Federal funding can help accelerate transportation projects—but successful ATTAIN applications […]
How Long Do Supercapacitors Last Compared to Batteries in Traffic Cabinets?
When agencies review backup power for traffic signal cabinets, runtime is only part of the equation. The more practical long-term question is how often crews will need to service, replace, or troubleshoot the energy storage system over the life of the cabinet. That question matters because backup power affects more than outage response. It influences […]
Ensuring Compliance (NEMA/ITS, BABA, Local Specs) In Traffic Cabinets
Procurement delays, failed inspections, or funding ineligibility can stall cabinet projects for months. This buyer’s checklist translates standards and funding rules into plain English—so you can spec, bid, and deploy with confidence. It’s focused on what Western Systems delivers every day: standards-compliant, U.S.-manufactured cabinets with complete documentation and a smooth path from design to acceptance. […]
Protecting Critical Infrastructure: Security Measures for Traffic Cabinets
When a traffic cabinet is compromised, the result is often more than a service call; it can be a public-safety incident. Unsecured doors, cut cables, or tampered controllers can darken an intersection, trigger flash, or disable priority signals that emergency vehicles rely on. This guide outlines practical physical and cyber measures that agencies can implement […]
