• Abstract:
  This project evaluated efforts by the Stafford County, Virginia, Sheriff’s Office to reduce speeding on roadways. Researchers coordinated to implement countermeasures on corridors with safety concerns where speed was a factor. Speed and enforcement data were collected to look at the impacts of the enforcement efforts. From this, the SCSO was able to make decisions on where countermeasures would be applied and what countermeasures would be implemented, including deputy presence with on-site enforcement, decoy cars, speed trailers with digital feedback signs, and changeable message signs. The SCSO also used social media to release public service announcements about the safety campaigns. Decoy cars proved to be the most successful activity that led to drivers reducing their speeds for more than a day. Speed trailers and deputies on-site issuing citations were also effective, but seemed to be localized. The study found the number of speeders to be a statistically significant predictor of crashes and showed that traffic volumes can increase without a concurrent increase in crashes if the increased volume is made up of non-speeders.
