TMC/Tagging scheme
This page describes the (old) tagging scheme for TMC tagging based on the following keys:
TMC:CID:TABCD:LocationCodeTMC:CID:TABCD:DirectionTMC:CID:TABCD:NextLocationCodeTMC:CID:TABCD:PrevLocationCode
See taginfo for the current state of use.
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.
TMC:CID:TABCD:LocationCode
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.
| CID | CCD (in messages)
first 4 bit of PI |
Country | bounding-box of radio-area |
|---|---|---|---|
| 17 | 0x1 | Germany (old?) | todo |
| 1 | 0x9 | Albania | todo |
| ... | 0x... | ... | todo |
| 29 | 0xD | Lybia | |
| ... | 0x... | ... | todo |
| 46 | 0xD | Serbia | todo |
| ... | 0x... | ... | todo |
| 58 | 0xD | Germany (current LCL) | todo |
| 6 | 0x6 | Belgium | todo |
| 7 | 0xF | Bosnia Herz. | todo |
| 8 | 0x8 | Bulgaria | todo |
| 9 | 0xc | Croatia | todo |
TMC:CID:TABCD:Direction
This key is used to indicate that the given map-element only represents this location-code in positive (/negative) direction and that another or other map-element(s) represent it if asked for the same location-code in negative(/positive) 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.
TMC:CID:TABCD:NextLocationCode
This key is used to give the next location-code in positive 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.
TMC:CID:TABCD:PrevLocationCode
This key is used 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.
Optional tags
The following optional tags may be used on all imported elements:
