The present invention relates to an integration-oriented intelligent speed trajectory optimization method and system for an autonomous train. The method includes: constructing an autonomous train speed trajectory optimization model under virtual coupling based on a discrete distance; converting the autonomous train speed trajectory optimization model into a Markov decision process; using a deep reinforcement learning algorithm TD3 to train a neural network and an agent in the Markov decision process, to obtain a trained neural network and agent; and deploying the trained neural network and agent to an autonomous train, to perform an autonomous train speed trajectory optimization decision, so that safe, efficient, and comfortable train autonomous operations can be implemented.
