The bus line shapefiles are generated from basic operating schedules for all trunk lines. Branch lines and short-lines are subsets of these lines. Example: Only Limited Line 344 is listed under Lim&Exp. The other Limited Routes (i.e., routes that skip stops) are branch lines that will be found under their parent trunk line (e.g., Limited Line 302 is a branch of Local Line 2).
The attribute file (dbf) of any bus line shapefile has a column, “Var_Route” which identifies the Trunk Line. A trunk line may have many rows associated with this Line. Each of these represent a trip pattern that may be assigned to a bus.
The attribute file also contains a column “Var_Descr” that further describes the trip pattern. A bus route that differs from the trunk line’s route (enough to be given its own Route number in the bus’ headsign) will be indicated in this column. In order to have a single bus line displayed on a map use your GIS software to highlight and/or export the trip patterns with that bus line’s name. |
