In view of the complex operation requirements of Guangzhou Metro Line 18 and Line 22,such as long sections and Y-type routing,this paper proposes corresponding fast and slow train operation solutions,and conducts data simulation through simulation tests to form a signal system solution under fast and slow train operation modes,providing effective technical support for signal system design of similar projects.
