Lane Control Signs

Lane control gantries are represented by the on the action panel. You can use the ATMS to:

When there are manual and default messages in the queue for the sign, the highest priority message will be displayed. The sources and priorities of messages are as follows:

MESSAGE SOURCE	DESCRIPTION
Manual	A message posted by you or another user to one or more signs for immediate display. These messages will be sent to the sign for display.
Default	The message configured for display when no other message is in the queue.
Blank	The default state when no default message is configured for the sign

LCS Gantry Icons

The gantry icons indicate the status of each gantry, whether the gantry is being used to display a message, and the relative priority of the displayed message. The gantry icon comes to a point, indicating where the gantry is located, and which direction of the road it displays messages for. The gantry icons you will see are as follows:

ICON	DESCRIPTION	DESCRIPTION
	Blank: An all-black gantry indicates that the gantry is displaying its default message, and that the default message is blank. The direction of this icon indicates that it is for the Northbound direction of the road.	North
	Low Priority: A gantry with single line of dots indicates a default message is displayed. This typically represents a non-blank default message on at least one of the signs in the gantry.	North
	High Priority: A gantry with two lines of dots indicates a high priority message is displayed. This typically represents a manual message on at least one of the signs in the gantry.	North
	Error: A gantry with a red border indicates at least one of the signs in the gantry is not communicating or has an error preventing the ATMS from controlling it.	North
	Disabled: A grey sign gantry indicates that all signs in the gantry have been disabled by a user. The ATMS will not communicate with the gantry while it is disabled, and will have no information about the current message or status of the sign.	East
