Georgia renews traffic monitoring contract

Georgia DOT (GDOT) USA has renewed its contract with Cellint Traffic Solutions for Atlanta through cellphone signal monitoring for real-time traffic information. It is the first time in the US that a project with such a system has been renewed based on successful results.
 
Cellint has been delivering cellular-based traffic information to GDOT on the Georgia 400 road and nearby arterials since 2006, when the fiber communications to the current sensors was disabled due to massive construction work taking place along the freeway. Mark Demidovich, GDOT’s assistant state traffic engineer said: "Deploying a replacement fiber 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."

Following Cellint’s successful project along the Georgia 400 and adjacent arterials, GDOT published an evaluation written by the Atlanta office of URS, which validated the system as a reliable solution for traveler information and road management in all speed ranges.

"We found that the percentage error varied according to speed category, but overall accuracy was good" said Demidovich, "The average difference across all speed ranges was 7-11km/h (5-7mph) which, to me, is good enough to act as a feed to NaviGAtor, Georgia’s real-time road information system”.

TrafficSense live data on the Georgia 400 in Atlanta, Georgia, has been displayed for about a year already on the NaviGAtor website. and is used by GDOT to feed its 511 telephone information system.
