As you drive, you may notice black cables across the road. These are portable traffic counters, crucial for traffic management and data collection. “These unassuming black cables… provide invaluable data” on road usage and traffic patterns, with over 12,000 scattered across the state.
The technology is simple yet effective. “Each time a vehicle’s tires contact the tube, a burst of air is triggered,” sending an electrical signal to a counter. This data helps track vehicle volume, speed, and direction, essential for decisions on road signage, speed limits, and transportation budgets.
Beyond counting, these tubes play a key role in enhancing road infrastructure and ensuring smooth traffic flow. Whether temporary or permanent, they capture vital traffic dynamics.
Next time you see these cables, remember they’re not just counting cars—they’re gathering data to improve our roads and keep traffic flowing efficiently.
