Description
TMC location-codes for points, roads and ways.
Group: Non-physical, TMC
Used on these elements
may be used on nodesmay be used on waysmay be used on areasmay be used on relations
Useful combination

TMC:Direction=positive TMC:Direction=negative TMC:NextLocationCode=* TMC:PrevLocationCode=*

Status: Unspecified

This key is used to add the TMC location-code to a map-element TMC/TMC_Import_Germany#Tagging_Schema. The fields:

  • (CID) is replaced by the country-id (e.g. 58 for Germany)
  • (TABCD) is replaced by the table-code (e.g. 1 for the only table of Germany).

These values are given in the national TMC LocationCodeList.

Note: a node can only have 1 location-code per cid-tabcd -pair. Use different, nearby nodes on intersections.

Note: the unique CID(e.g. 58) used here is not the transmitted but a non-unique CCID(e.g. 0xD) and mapped to the CID via COUNTRIES.DAT of the LCL.

usage

These codes are send via broadcast-radio and satellite-radio as the location-identifier for traffic-messages (e.g. traffic jams and accidents). Such locations are identified by a location-code and optionally a direction + extend. Many location-codes have clearly identified next and previous location-codes. Direction can be forward or reverse and extend is the number of steps in that direction.


optional tags

The following optional tags may be used on all imported elements:
