Current fluency data

NOTE ‼️ End of life on August 31, 2017! Start using new REST/JSON-APIS before that.

Only links of Helsinki Metropolitan Area are measured. Link numbers are one to three digits long and under 1000 for Helsinki Metropolitan Area.

The message contains for each link the latest 5 minute median, corresponding average speed, fluency class, and timestamp of the latest update.

The message is updates each time we receive new median data from MTP. Normally this is once per minute. If MTP does not send us new data, the message is not updated.
