Description: Two drone radar units were deployed at a rural Interstate work zone where traffic was limited to one lane in each direction for a reconstruction project. Speed data were collected at several locations over about a 1-mi segment for a week prior to deployment and a week following deployment. Some speed differences observed between the before and after data were statistically significant, but the differences were inconsistent. In some locations the speeds decreased after deployment, and in other locations they increased. No explanations for the changes could be identified, but their inconsistency suggests that the radar drone is not an effective speed control device.
