Abstract

Systems, methods, devices, and apparatuses for intelligent traffic signaling are disclosed. The system can include sensors for detecting approaching automobiles. The system can include a processor operable to receive data directly from nearby automobiles and detected data from the sensors. The processor can determine, based on the detected or received data, a level of safeness associated with crossing the opposing traffic lane. The level of safeness can be calculated by at least determining an expected time to arrival of an approaching automobile at the traffic intersection. The system can control one or more traffic beacons based on the level of safeness.
