The Echo monitors the traffic volume on the highway's mainline lanes. When traffic levels hit a defined volume threshold, a notification is sent, and the system automatically opens the median shoulder lane to allow vehicles to start using the lane. The additional lane is typically used during weekday morning and afternoon rush hours. Since the Flex Lane has been in use, travel times have been reduced on average by 45% and drivers have noticed less congestion and traffic congestion on the Beltline.
