1、DCISThe Digital Controller Interface StandardDIGITAL TWINS OF SIGNALS FOR A CONNECTED FUTURE Overview/RecapDCIS(Andy Graham,Peter Routledge,Jon Wade and Mark Pleydell)is implementing three standards defining1.The number and type of signal-controlled sites in the UK2.The topology of each site and loc
