ATSC systems can reduce vehicle wait time by 40%, cut travel time by nearly 26%, and lessen vehicle emissions by 21%, according to Carnegie Mellon University. Digital traffic signals can dispatch pre-processed and raw data to a connected cloud-based control center, such as an intelligent transport system (ITS).

Roundabouts are a safer alternative to traffic signals and stop signs. The tight circle of a roundabout forces drivers to slow down, and the most severe types of intersection crashes — right-angle, left-turn and head-on collisions — are unlikely.
