The application discloses a kind of security automatic driving methods based on double alternative diffusion strategy, for the problem that traditional off-line reinforcement learning may cause unsafe behavior in automatic driving task due to extrapolation error, propose to use two diffusion models as mutually alternative strategy, and use integrated network containing multiple action value networks as policy evaluation network;By training two diffusion models and integrated network in offline environment, the uncertainty of the actions generated by the two strategies is evaluated using the integrated network during the deployment phase, and the strategy with lower uncertainty is selected as the final driving strategy, thereby ensuring the safety of the automatic driving task during the deployment phase.

This invention relates to a method for selecting a coordinated operation strategy for urban rail transit and urban rail transit trains, comprising: constructing a set of alternative operation strategies for urban rail transit and urban rail transit trains from the perspectives of routes, stops, and train formations; determining feasible strategies suitable for urban rail transit and urban rail transit trains based on the set of alternative strategies; and establishing a coordinated optimization model for the operation schemes of urban rail transit and urban rail transit trains based on the feasible strategies, and solving for the route departure frequency, stop scheme, and train formation number under each feasible strategy. This invention provides a clear answer to "which operation organization level strategy to adopt" in specific situations of multi-mode rail transit, thereby making up for the lack of a set of operation organization level strategy selection methods for urban rail transit and urban rail transit to cope with variable passenger flows.
