Network Linear Feature ID (NLF_ID):
The network linear feature identifier is commonly referred to as the NLF_ID. The NLF_ID is a 14 character code which uniquely identifies a section of road within the Base Transportation Referencing System. This program uses the id to lookup ADTs and Truck %s for that section of roadway. With the NLF_ID and a county true log point, one can locate a section of roadway within the state of Ohio.
