Police radar is known to have an effect on the speed of drivers. This effect derives from the presence of vehicles equipped with radar detectors in the traffic stream. The most common method for determining radar detector use is visual examination of the traffic stream. Other methods employ specially developed receivers, often called radar detector detectors. As a response to the development of such a radar detector detector, radar detector manufacturers inserted countermeasures in their designs with the objective of avoiding their detection. Presented is the Georgia Institute of Technology Research Institute radar detector detector, which was developed by using advanced surveillance technology and handles the countermeasures of current radar detectors. This system was used to determine radar detector densities at three sites (rural two-lane road, four-lane state route, and six-lane Interstate) around the Atlanta, Georgia, metro area. The data collected were analyzed and compared against commonly used statistical probability distributions. Common distributions were fitted to the data, whenever appropriate. The determined radar densities by site and time of day were compared by using a nonparametric analysis of variance test. This analysis revealed that facility type has a significant impact on radar detector density, whereas time of day showed a significant effect for only one of the sites (state route).
