First modeling and evaluation of the data |
For this exploratory analysis, the following questions were chosen as a starting point:
- How good is the data quality?
- How comparable are the measurement cross-sections with each other?
- What are the criteria or boundary conditions for future measurement campaigns?
- How do environmental influences generally affect the track superstructure and specifically the noise?
- What influence do the new rail pads and the under-sleeper pads of the concrete sleepers (B-91) have on the noise?
