York County company testing automated flagging for work zones
A local contractor is now using automated flagging devices connected through a tablet with real-time video, providing an alternative to placing flaggers in harm’s way.
According to D.E. Gemmill Inc. president David Gemmill, the new system will remove flaggers from the traffic flow, creating a safer work environment.
"Flaggers standing in traffic are constantly in danger," Gemmill said.
The Guardian SmartFlagger is controlled by a single employee onsite who can monitor traffic flow, manually raise and lower the flagging arms or set the system up for timed, automated use. Two video cameras incorporated into each SmartFlagger provide a live feed to the operator and a video record of the job site.
D.E. Gemmill trained on a Kinsley Construction job site on Florida Avenue in York City the week of March 4 using the new automated flagger assistance device.
According to a D.E. Gemmill news release, recent statistics show that there is a work zone crash every 5.4 minutes. Nationwide, about 800 people are killed annually in work zone crashes, and another 42,000 are injured, according to the release. Removing human flaggers from the traffic flow will reduce the number of injuries in these crashes, Gemmill said.
While creating a safer work zone, the technology doesn't create a cost increase.
"It is extremely competitive with normal flagging operations," Gemmill said.
With the new system, only one operator instead of the normal two or more flaggers is needed at each site, so the company can offer the service for about the same cost, he said.
