Latest Patents

Eric D Holm holds a patent for a "System for measuring average speed and traffic volume on a roadway." This vehicular traffic sensor is capable of measuring traffic speed and volume in all weather conditions and at a low installed cost. The sensor utilizes multi-path interference of ambient radio frequency (RF) signals, which can include control signals transmitted by cellular telephone base stations. As vehicles travel along the roadway, they reflect RF signals in various directions. An antenna mounted near the side of the road detects both the transmitted signals and those reflected off the vehicles. Variations in the amplitude of the combined signals are processed to determine traffic speed and volume. This information can then be sent directly to a traffic management center, providing an inexpensive sensor for wide-area traffic monitoring.
