Abstract
Systems, methods, devices, and apparatuses for intelligent traffic signaling are disclosed. Standalone traffic signals are equipped with a plurality of sensors including RF, radar, Wi-Fi, and cellular sensors, etc., for detecting approaching automobiles in an opposing traffic lane. The traffic signal is controlled by a processor at an attached or nearby controller box, and the processor is operable to receive speed, location, and heading data directly from nearby automobiles. The processor determines, based on detected or received data corresponding to approaching automobiles, a level of safeness associated with crossing the opposing traffic lane. The level of safeness is calculated by determining an expected time to arrival of an approaching automobile at the traffic intersection, and comparing the expected time to a width of the opposing traffic lane. A light pattern at the traffic light indicates the calculated level of safeness.
