Streets TMC (Streets_TMC)

The Streets TMC (Streets_TMC File Geodatabase Table) table represents Navigable Links (road networks) in North America.

The TMC (Traffic Message Channel) coding is a mechanism to connect TMC-based dynamic traffic information to the HERE maps. The TMC codes represent pre-defined code available in so-called Location Tables. These TMC codes enable cross-referencing between TMC-based traffic messages and HERE map features.

This layer contains the following fields:

Field Name Description Values
OBJECTID Internal feature number Sequential unique whole numbers that are automatically generated.
EdgeFCID Edge Feature Class ID The Feature Class ID corresponding to the edge element.
EdgeFID Edge Feature ID The Feature ID corresponding to the edge element. The Edge Feature ID is an Esri specific ID and refers to the Object ID in the Streets layer.
EdgeFrmPos From Edge Position The From position along the linear feature that represents the edge element. This allows for the usage of streets composed of multiple edge elements.
EdgeToPos To Edge Position The To position along the linear feature that represents the edge element. This allows for the usage of streets composed of multiple edge elements.
TMC TMC Code

Traffic message channel (TMC) codes define standard unique identifiers used for getting live traffic speed and representing the associated road segment. A TMC code consists of a combination EBU Country Code (for example "5"), Location Table Number ("03"), TMC Path Direction ("+"), Location Code ("05548").
