Abstract
A system and method for avoiding collisions in a traffic intersection using radar sensors is disclosed. The system detects the location, speed, size, and direction of travel of objects, including vehicles and vulnerable road users, in and approaching a traffic intersection. Using this information, trajectories for all objects are determined, and, if a likelihood of a collision is determined, one or more traffic signal transitions are delayed in an attempt to avoid the collision.
