"bidirectional traffic flows in orderly manner without stop-and-go, even in great numbers... trajectories of ants reconstructed by deep learning algorithms, tracking individual ants' movements, mapping speeds, flows densities... ants follow pheromone trails marked by leader, move in platoons with small gaps and no overtaking... smart roads using advanced communication technologies to communicate with each other and road infrastructure management... enables high speeds with close spacing across parallel lanes"
