Nice proceedings again. In addition to the minor code remarks I made, there is one thing to improve: when an alert concerns many entities, they should be presented in sorted order. It is difficult to detect a single route from a list of 100.

Most remarks got fixed, but some more left to do:

• TrafficNowTransportModes contains citybikes, which is wrong

• Filter list should be an intersection of config.transportModes and TrafficNowTransportModes. It makes no sense to show subway filter in Rovaniemi.

• In hämeenlinna, there was an alert with lots of unknown entity types and a few stopOnRoute types. Alert got filtered when bus filter was set although stopOnRoute referred bus routes. This feels a bit wrong.
