Dark cables stretched across roads may seem insignificant, but they play a vital role in traffic management. These pneumatic tubes are part of a clever system that collects critical data on vehicle count, speed, and direction. Transportation professionals rely on this information to plan safer and more efficient roadways, shaping decisions about speed limits, signage, and infrastructure funding.
When a vehicle tire compresses the tube, a burst of air triggers a counter device, recording each crossing. Dual-tube setups capture more detailed insights, such as vehicle classification and travel patterns. With over 12,000 of these devices statewide, they help analyze peak traffic times and validate citizen concerns about road safety, like speeding or shortcutting.
Beyond counting, these versatile tools assist in designing traffic strategies and refining transportation systems. Whether temporarily or permanently placed, they silently monitor road activity, guiding the development of smoother, safer streets for everyone.
