Would you slow down if a roadside sign warned of animals ahead?
Virginia Tech Transportation Institute finished a one-year pilot of an automated wildlife detection system on a 14-mile stretch of Route 460 in Southwest Virginia. Drivers approaching activated warning signs slowed by an average of 3 mph, and the project was sponsored by the Virginia Department of Transportation.
Why it matters
Collisions involving elk average more than $80,000 per crash, according to the project's feasibility study, so the economic and safety stakes for drivers in elk country are high. The pilot tested whether roadside sensing and warnings can slow traffic before a large animal reaches the pavement.
The system covered a 750-meter monitoring section using eight portable, solar-powered trailers and dynamic message signs. Detection accuracy was 97 percent for medium and large wildlife, based on data from more than 10,000 passing vehicles.
The players
Virginia Department of Transportation
The state agency that sponsored the pilot and oversees Virginia's highway system and roadside safety programs.
Virginia Tech Transportation Institute
The university research institute that completed the one-year wildlife detection pilot and collected the driver data.
Crosstek
A provider that supplied off-the-shelf cameras and AI software used for wildlife detection in the system.
T-Mobile
A wireless carrier whose 5G cellular network and satellite service supported remote monitoring of the system.
The details
Thermal cameras and AI software monitored the roadway and shoulders for medium- to large-sized animals, and roadside signs activated when one was detected. Crosstek supplied off-the-shelf cameras and AI software, while T-Mobile's 5G cellular network and satellite service handled remote monitoring. The signs alerted motorists to elk and other large animals, and the average 3 mph slowdown was measured among drivers approaching activated signs.
Timeline
One-year pilot period on Route 460, ending in September 2026.
The Big Picture
The Route 460 pilot tests a portable, solar-powered thermal camera system with dynamic message signs as a deployable model for wildlife crossings. Project lead Talledo Vilela believes it could be used in other areas where animals frequently cross roadways.
If you drive regularly through elk or large-game country, watch for dynamic warning signs and reduce speed when they activate. Keep your auto insurance and roadside assistance information current, and plan for longer drive times on rural corridors.
The takeaway
Roadside warning systems can measurably change driver speed near wildlife, and a 3 mph reduction is one practical result. If you travel elk country, treat activated wildlife signs as a cue to slow down and give animals room to cross.
