TMC location data

RDS-TMC is a traffic message channel, which relays traffic information through analog FM radio's RDS channel. Traffic information includes useful and real time data about road works, accidents, traffic jams and weather. The TMC/ALERT-C material is necessary when using the traffic information. Finnish Transport Agency is responsible for administration and distribution of the Finnish TMC data. TMC is developed by the Tisa Forum.

The Finnish TMC location database is constantly updated and certified yearly by TISA forum.

For incident broadcasting Finnish Transport Agency uses more frequently exported versions of the database. These intermediate non-certified versions are offered as open data, and differ slightly from the certified version. You can review the documentation for details on the differences.
