In 2017, a Bavaria-wide pilot project to measure the volume of motorcycles was carried out by the Bavarian Police Department.

Neukirchen, in cooperation with the neighboring municipality of St. Englmar and initiated by council member Matthias Wallner, is taking on a pioneering role in Bavaria in the fight against motorcycle noise.
