A system for deadlock precaution and prevention in autonomous vehicles (AVs) includes: AVs having actuators and sensors. The actuators alter a dynamic state of the AVs, and the sensors capture vehicle state and environmental information. The system receives vehicle state information and predicts a host AV trajectory, and trajectories of other vehicles approaching, entering, or within an intersection. Multi-directional conflicts identification per driving direction (MDCIPD) messages and vehicle state information are transmitted to a cloud computing device. Waiting relations for deadlock prevention are based on the MDCIPD messages and vehicle state information, and a deadlock precaution notification (DPN) and/or a deadlock prevention coordination instruction (DPCI) are generated. The AVs perform advanced driver assistance system (ADAS) functions via the actuators in response to the DPN and/or DPCI, and cause the AVs to avoid deadlock at the intersection.
