Streets TMC table (Streets_TMC)

The StreetsTMC table provides Traffic Messaging Channel (TMC) information for a link. The TMC coding is a mechanism to connect TMC-based dynamic traffic information to the HERE maps.


For a description of the attributes OBJECTID and GlobalID, see Esri® system fields .

Field nameData typeDescription
LINK_IDInteger (4)Unique ID of the link to which the TMC code applies. References the LINK_ID field in the Streets layer.
EBU_COUNTRY_CODEString (5)Defines EBU (European Broadcasting Union) country as associated to the Location Table from where the TMC code is derived.
LOCATION_TABLE_NRInteger (4)Identifies the location table number, as assigned by the Location Table provider
TMC_PATH_DIRECTIONString (1)

Indication of direction as defined in the Location Table

  • N - Negative Direction, internal to Point Location
  • P - Positive Direction, internal to Point Location
  • - - Negative Direction, external to Point Location
  • + - Positive Direction, external to Point Location
LOCATION_CODEString (5)Location Code is the Point Location code assigned to a link.
ROAD_DIRECTIONString (1)

Road Direction is the identification of the TMC coding direction relative to Direction Of Traffic (on-way) coding in the HERE database. This is only published for TMC codes on bidirectional links.

  • B - Both directions
  • F - The direction of travel from the reference node
  • T - The direction of travel to the reference node
TRAFFIC_CODEString (15)Concatenation of Ebu_Country_Code, Location_Table_Nr, Tmc_Path_Direction and Location_Code
EDGEFRMPOSDouble (8)Works in conjunction with EdgeToPos to identify a direction of travel or side of the street. Zero indicates the beginning of the line feature as defined by its digitized direction. One indicates the opposite end.
EDGETOPOSDouble (8)Works in conjunction with EdgeFrmPos to identify a direction of travel, or side of the street.
EDGEFIDInteger (4)The OBJECTID for this segment in the Streets feature class.
EDGEFCIDInteger (4)The feature class ID for the Streets feature class.
TMCString (15)The TMC code representing the associated road segment. Associates data from the live traffic feed.
LEFT_REGION_LATINString (100)Name of the region on the left hand side of the street segment.
