Queue Detection Trailer

Accurate, up to date traffic data is imperative to effectively manage your work zone. Having the proper detection equipment integrated into your area, such as the Queue Detection Trailer, will provide just that. The Queue Detection Trailer is a portable trailer that provides a versatile and lightweight platform with a small footprint to collect a variety of real time data information, such as speed, volume, and occupancy for up to 22 lanes of traffic. Within Smart Work Zones, Hill & Smith Inc. is the exclusive distributor of Wavetronix’s industry-leading detection devices. When attached to the Queue Detection Trailer, the SmartSensor HD collects all the essential data that you need, such as average speed, volume, occupancy, and classification. Providing the highest quality sensor ensures that real time data is going to be as accurate as possible. The final product is a much safer environment for all incoming motorists.
