Development of Practical Roadside Sensor Utilizing Millimeter-Wave Radar Technology

Abstract

This article reports the results of a research initiative to apply high-resolution millimeter-wave radar to roadside sensors for the purpose of reducing pedestrian accidents using cooperative driving support. Millimeter-wave radar technology installed at intersections and the like can realize sensing functions, such as the detection of pedestrians and bicycles with high accuracy, regardless of the weather and time. To facilitate the practical adoption of this technology, detection processing software compatible with high-resolution radar has been developed and verified under severe weather conditions such as hard rain and snowstorms. A prototype 79 GHz band millimeter-wave radar system was installed at actual intersections to evaluate the detection performance of crossing pedestrians and so on. This report mainly describes the development of the radar technology and the progress of the public road experiment.
