US breakthrough for cellular-based traffic monitoring solutions
Cellint Traffic Solutions, a leading provider of real-time traffic monitoring solutions based on cellular data, has had its contract for covering part of metro area Atlanta renewed by the Georgia Department of Transportation (GDOT), after a successful independent evaluation. Cellint claims this is an unprecedented achievement for the cellular-based monitoring industry, since it is the first time in the US that a project with such system was renewed based on successful results.
Cellint has been delivering cellular-based traffic information to GDOT since 2006 on Georgia 400 and nearby arterials, after fibre communications to the current sensors was disabled due to massive construction work along the freeway.
Mark Demidovich, GDOT’s Assistant State Traffic Engineer said "Deploying a replacement fibre backbone, from plan creation to completion, would have taken over two years. Cellint was able to have an alternative in place in four months, which demonstrates another potential advantage of the cellular systems – speed of deployment.
"We found that the percentage error varied according to speed category but overall accuracy was good" continued Demidovich, "The average difference across all speed ranges was 5-7 mph [7-11 km/h] which, to me, is good enough to act as a feed to NaviGAtor, Georgia’s real-time road information system".
