Segment Closure Files

Segment closure files are used to select roadway segments (previously defined in the segment definition file) which are closed or which for other reasons should be drawn in the color specified for "No Data Available." These files are typically used for the HOV display where a large number of segments do not have HOV lanes but are needed to visually complete the map.

Each line in the closures file must contain one string which is the identifier of a roadway segment that was defined for the map in which this file is used.

Closure files are stored in the \TrafficChannel\closures directory. The following sample is a partial listing of the hovclosures.seg file:
