Abstract
A novel system and method of integrating an RF emissions device, such as a radar system (A), within a traffic control indicator () system. The system and method determines, using LFM-CW radar signals () and a multi-stage spectral processing algorithm (), if one or more object/vehicle targets will enter an intersection and comprises receiving a radar echo response () indicating the object/vehicle target () is approaching the intersection, receiving range and velocity of the object/vehicle targets (), and based on the receiving, determining if the object/vehicle target () will enter the intersection. The system and method can programmatically be configured to activate red-light-hold, green-light-extension, or left-turn-warning.
