Highway 6 Low-Volume Detector Testbed and Roadside Equipment Laboratory

Additionally, the site has been served by multiple types of communication. In effect, not only has the site provided a sensor testbed, but researchers have also constructed a communications testbed to examine the effectiveness of different communications solutions in accessing and transporting data from remote sites.

The state highway 6 low-volume detector testbed in College Station has the following equipment: a pole with mast arms to support test devices, a fenced concrete pad with three large equipment cabinets and a weather station, power, and communications. The three large traffic cabinets are interconnected via six-inch conduit, and they house and provide protection for computers, a vehicle classifier, video processors, communication hardware, and terminal strips for inductive loop detectors. There are three WIM systems and a wide variety of non-intrusive freeway detection equipment installed at the site. The testbed has two horizontal bores under the pavement that house 3M microloop probes in both southbound lanes. Technologies that have been tested include magnetic, radar, video imaging detectors, active infrared, and acoustic devices. The roadway at this site has a good mix of different classes of vehicles.
