The Transportation Systems group works with the Georgia Department of Transportation (GDOT) to develop innovative automation systems to make highway maintenance and monitoring more efficient and less costly. Researchers also work with state and federal agencies to monitor and reduce the environmental impact of vehicular emissions using remote sensing technology and specialized evaluation methodologies.
Researchers are developing an automated system for rapid deployment to allow collection of pedestrian and cyclist’s behavior data at signaled and un-signaled intersections and mid-block to allow for development of models for input into future intersection and signaling/marking design.
Sealing cracks in roadways ensures a road’s structural integrity and extends the time between major repaving projects, but conventional manual crack sealing operations expose workers to dangerous traffic and cover a limited amount of roadway each day. To address these challenges, the Transportation research group developed a prototype automated pavement crack detection and sealing system with funding from the Georgia Department of Transportation.
A typical Raised Pavement Marker placement operation includes four vehicles and a six-person crew. All the vehicles must stop at each marker location, so there is tremendous wear on the equipment and increased fuel use. The Georgia Department of Transportation believed there was a better way to do it and funded the Transportation research group to develop a first-of-its-kind system capable of automatically placing RPMs along the lane stripes while in motion.
Georgia Tech researchers use remote sensing equipment to monitor emissions from vehicles in the metropolitan Atlanta area. Their long-term work has validated the effectiveness of emissions control strategies.
