Realtime Traffic Messages

Update: constantly improving the decoder …

I finally set up a small embedded linux computer (ZFx86 @ 100MHz, 32MB) with one of my mp5_redux PC104 add-on boards to receive and decode TMC (Traffic Message Channel)-messages out of RDS (Radio Data System).

The system is set up to receive SWR3 (coverage: nrw, hessen, rheinland-pfalz, saarland, baden-württemberg, bayern) and Bayern 3 (coverage: bavaria) simultaneously, decode each datastream and write the combined data to a sqlite database. The database-file is pushed to the alrightythen-server every 5 minutes. Here a php-script does the extra Geo-RSS formatting. This adds up to 10mins delay to the data.

Please note: This is just for demo purposes. It is not guaranteed to be exact, up-to-date or even available … Although i expect it to be available and up-to-date (with ~10min delay)  from around 7:30 to 20:00.

If you are interested in the technology involved in receiving, decoding or publishing, mail me .

I have added the feed to GeoFeeder too.
