The invention discloses a traffic signal lamp adaptive timing control method based on deep reinforcement learning. The method comprises the following steps: obtaining a real-time traffic state based on a pre-constructed urban intersection model; based on the real-time traffic state, a theoretical optimal action is generated through a pre-trained traffic signal control model based on a depth deterministic strategy gradient algorithm, the theoretical optimal action comprises a plurality of single actions in one-to-one correspondence with the traffic lights, and each single action comprises an action state and an action duration; comparing the theoretical optimal action with a predetermined standard action interval, and correcting the theoretical optimal action according to a comparison result to obtain an actual optimal action; and controlling the traffic signal lamp based on the actual optimal action. The invention provides a traffic signal lamp adaptive timing control method and system based on deep reinforcement learning. The traffic signal lamp adaptive timing control method and system can control traffic signal lamps more flexibly and accurately.
