About the research
The CB Wizard was deployed on a sub-urban Interstate north of Wichita, in advance of a lane closure. Lane distribution data were collected at several distances from the taper to determine if vehicles changed lanes earlier due to hearing the warning message broadcast by the CB Wizard. System deployment and use was quick and easy. No changes were observed in lane distributions, so the effectiveness of the device could not be statistically verified.
