About the research

The speed monitor display used in this study included a solar power panel, which was mounted atop the box. This panel supplied power to the unit, and excess power was stored in a solar car-type battery housed in the box. The K-band radar used in the system broadcasts a directional radar beam over approximately one mile.

In September 1999 the speed monitor display was deployed at a work zone on Interstate 35. The purpose of this field test was to evaluate the impact of the speed display on reducing vehicles’ speed and increasing speed uniformity at work zones.
