Committee discusses automated traffic enforcement and predictive safety analytics; Prince William pilot cited
Summary
Members recommended automated enforcement paired with predictive safety analytics to target high-risk locations. Prince William County and other local pilots were presented as preliminary evidence of reduced speeds in school zones.
Committee members said automated traffic enforcement and predictive safety analytics could help address speeding and severe crashes in Northern Virginia and recommended pairing enforcement with data-driven targeting.
Prince William County staff said the county launched a pilot roughly 18 months ago that included red-light cameras and speed cameras in construction and school zones. "We're still in the process of collecting information to kind of do an analysis," Evan Santos of Prince William County said, adding that preliminary reports from police and transportation staff indicate the cameras have acted as a deterrent.
"We also did an automated student enforcement report and found that speeds went way down in school zones," Hillary Orr of Alexandria said, noting that citation counts fell after an initial warning period and improved detection reduced false citations.
Several participants asked NVTA to consider pairing automated enforcement pilots with predictive analytics to identify the intersections or corridors most in need of safety investment. "If we can actually figure out a way to find and target the actual intersections or locations where that's happening, then we can find a way to do actual physical changes," Mike Garcia of Fairfax County said.
Why it matters: Members said speeding and severe crashes remain a significant public-safety concern and that targeted, data-driven enforcement and engineering changes could reduce incidents in high-risk locations.
Next steps: Members urged staff to collect and share pilot results from jurisdictions (Prince William County, Fairfax County, Arlington, and statewide VDOT pilots) so the committee can better understand outcomes and potential performance metrics for NVTA-funded projects.
Ending: Staff said they would seek presentation(s) at future meetings to share pilot evaluations and recommended the committee track automated enforcement outcomes alongside predictive analytics as potential 2026 work items.
