View ➔ Lane Use ➔ LCS menu item
A lane-use control sign (LCS) is a sign which is mounted over a single lane of traffic (typically one for each lane). It can display a set of indications which either permit or restrict use of that lane.
These are some typical lane-use indications:
An intelligent LCS is a full-matrix color DMS mounted directly over a lane of traffic. In addition to being used as an LCS, it can display variable speed advisories, or any operator-defined message as a regular DMS.
A lane-use MULTI associates an indication with a message pattern. The message typically contains a graphic image of the indication. To be used, the hashtag must match the DMS.
A changeable LCS device is much simpler than an ILCS. It can display one of these indications:
Each indication must be assigned to a separate IO pin on a controller, as well as the DMS which represents the LCS.
