Description

This key is used with TMC:LocationCode=* to give the next location-code in negative direction. 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.

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.
