Abstract: Interoperability of FAO system no longer requires drivers to monitor train operation at GoA4. In terms of the division of responsibility on train safety monitoring between human and system, interoperability of FAO system is clearly different from interoperability of CBTC system. Therefore, the existing overlap release scheme for interoperability of CBTC system is no longer applicable to interoperability of FAO system, and there are safety risks. This paper focuses on the normal overlap release methods when the train has stopped at the platform. First, this paper analyzes the applicability of existing overlap release scheme; Then, this paper proposes two optimization principles including using the train control level information from onboard signaling equipment and using the overlap authorization information from trackside signaling equipment, and proposes the corresponding overlap release optimization schemes. Finally, this paper compares the advantages and disadvantages between the above-mentioned overlap release optimization schemes, and presents suggestions for use which met the actual demands.
