Display Optimization and Lighting Circuit Design for Urban Rail Transit Main Line Signal lights

On the basis of CBTC signaling system in moving block interval, the weakness of current urban rail transit signaling system display scheme is analyzed. An optimization scheme where green-yellow and blue signaling is added to the urban rail transit main line is proposed, and the feasibility of it is discussed. The signaling system lighting circuit design after optimization is expounded, and the working modes of the lighting circuit under different conditions is described.
