Description: The Road Segment table describes the administration and ownership of the segment of road. It contains tabular polyline data showing the log miles/measures, road name, functional class, administrative system, government control, urban area, incorporated area, metropolitan planning area, HPMS sample ID, U.S. Routes, special systems, state designation, state aid, open/proposed/ferry status, and sub route designations for the roadway. Road names are derived from visual surveys by field crew or official GIS maps. Functional class is set by the Federal Highway Administration (FHWA) and administrative system designation depends on the functional class. All other categories are determined by state and local agencies.County– County in Tennessee where associated features and attributes are located.Route Number– Route in Tennessee with corresponding attributes.Special Case – Route designator for non-standard routes such as By-Pass.00 None01 Spur - S02 Alternate - A03 State Connector - C04 Bypass - BP05 Business Route - BR06 Northbound - N07 Southbound - S08 Eastbound - E09 Westbound - WCounty Sequence – This number indicates the sequential number of times a route enters and leaves the county, begins with zero (0).Beginning Log Mile (BLM)– The beginning log mile (measure) for the route segment.Ending Log Mile (ELM) - The ending log mile (measure) for the route segment.Functional Classification – These codes, set by the FHWA, provide a statewide highway functional classification in rural and urban areas to determine functional usage of the existing roads and streets.01 Rural Interstate02 Rural Other Principal Arterial03 Rural Freeway or Expressway06 Rural Minor Arterial07 Rural Major Collector08 Rural Minor Collector09 Rural Local11 Urban Interstate12 Urban Freeway or Expressway14 Urban Other Principal Arterial16 Urban Minor Arterial17 Urban Collector19 Urban LocalAdministrative System – These codes are generally related to a funding source.01 Interstate, Rural02 Interstate, Urban03 NHS Rural, State04 NHS Rural, Non-State05 STP Rural, State07 STP Rural, Non-State09 Other State Highways, Rural10 Other State Highways, Urban11 Other County Roads12 Other City Streets13 NHS Urban, State16 NHS Urban, Non-State18 STP Urban, Non-State19 State Park20 Federal Park or Reservation21 STP Urban, State22 Rural Road System23 Private25 NHS Airport Connector26 NHS Port Connector27 NHS Amtrak Connector28 NHS Rail/Truck Connector29 NHS Intercity Bus Connector30 NHS Transit Connector31 NHS Pipeline Connector32 NHS Ferry ConnectorGovernment Control– These codes determine ownership and maintenance responsibility.01 State Highway Agency02 County04 Municipal11 State Park12 Local Park21 Other State Agency25 Other Local Agency26 Private27 Railroad40 Other Public60 Other Federal Agency63 US Fish and Wildlife64 US Forest Service66 National Park Service67 TVA68 Bureau of Land Management70 Corps of Engineers (Civil)72 Air Force73 Navy or Marines74 Army80 OtherIncorporated Area Number – Valid City CodeUrban Area Number – Valid City/Urbanized Area CodeStudy Area Number– Valid City CodeSpecial Systems (Use up to six Special System columns) – These codes are provided to assist in defining additional special uses, special designations, etc.01 None02 US Forest Highway03 US Forest Development Road04 US Park Service Parkway05 Nat’l Park Roads and Trails07 State Park Road08 STRAHNET10 Appalachian Development Highway11 US Truck Route12 TN Scenic Highway13 TN Parkway14 Federal Scenic By-Way15 County Park16 (23 U.S.C. 139(a)) Addition to the Interstate System17 (23 U.S.C. 139(b)) Future Addition to the Interstate System22 State Aid SystemTN Bicycle RouteCity Park25 Great River RoadHPMS Donut SampleSpecial Systems 2 – Same as Special SystemsSpecial Systems 3 – Same as Special SystemsSpecial Systems 4 – Same as Special SystemsSpecial Systems 5– Same as Special SystemsSpecial Systems 6 – Same as Special SystemsUS Route Number (Use up to six US Routes for a road segment) – US Route Number assigned to roadway segment.US Route Number 2US Route Number 3US Route Number 4US Route Number 5US Route Number 6Road Name – The name assigned to roadway segment.Proposed Route or Ferry – Status of route:O – Open to publicP – ProposedF – FerryNULL – No code assignedHPMS Section ID– HPMS Sample ID
