I'm just getting started working with TMC (Traffic Message Channel) data and I'd like to know how to use the location codes to get coordinate data for points. Is there a mapping somewhere I could use? I'm considering using traffic data from TTWN for the US.

  • Could you provide more information, where is the original data (TMC), who makes it, and if possible the original format? I know that INRIX provides data through TMC's, but you need to buy a proprietary system to link the files to a map. – Daniel Miller Aug 12 '16 at 13:21
  • Also, could you give an idea of the country? – Daniel Miller Aug 15 '16 at 13:25

TMC Location lists are not that open, but some European countries offer them up to the public.
OSM them into OSM data, you could use OSM TMC or try to reverse engineer it.
As far as decoding goes: linux flavor

  • Thanks Albert. What do you mean by "OSM them into OSM data, you could use OSM TMC"? I'm quite keen on converting TMC locations to an OSM format but so far all I've been able to discover for mapping the two seems limited to some European countries: wiki.openstreetmap.org/wiki/… – k-r Aug 17 '16 at 22:09
  • sorry, osm can read/convert tmc, so i meant, use osm to convert tmc. however, as you pointed, the only data available is for the european counties i mentioned. not quite sure how i missed that. my bad. – albert Aug 18 '16 at 2:47
