Alex Hainen, an assistant professor in UA’s Department of Civil, Construction and Environmental Engineering, also works in conjunction with ALDOT in the Traffic Management Center on the UA campus. He presented a series of studies that are ongoing to optimize traffic signal flow throughout the Tuscaloosa and Northport area using data compiled by the DSRC radio network. Through data collection methods first begun in 2009, Hainen said applying different mathematical algorithms to the signals has increased the amount of time drivers encounter traffic signals with a green light from Kauloosa Avenue to University Boulevard. “Our goal is to get them arriving on green, get them through the intersection and keep on going,” Hainen said.
