You may have noticed black cables stretched across roads. These are traffic counters used by transportation professionals to gather data on traffic patterns and road usage. When a vehicle drives over the cables, it triggers an air burst that signals a counter device, tracking vehicle numbers, speed, and direction. Over 12,000 of these counters are placed across the state, providing valuable data for traffic management decisions, such as speed limits and road planning. These simple devices play a crucial role in optimizing traffic flow and ensuring safe street systems.
