Railways database

[IsotoCedex]

Good morning NoiseModelling Team,

We are planning to include the Spanish railway database (fixed and moving parts) and would like to know which of the databases in the following link the software is using.

noisemodelling-emission/src/main/resources/org/noise_planet/noisemodelling/emission/railway

Thank you!!

Ignacio

Hello,

Nice. We are currently working on dynamic train noise modelling with @Adrien-lb (second per second noise emission). So you will see updates about it in the next months.

There is 3 set of files:

• Train composition file specification of the composition of a train (one train can contain one or more vehicles).'
  https://github.com/Universite-Gustave-Eiffel/NoiseModelling/blob/v5.0.0/noisemodelling-emission/src/main/resources/org/noise_planet/noisemodelling/emission/railway/RailwayTrainsets.json
• Vehicles characteristics file
  coefficients related to the characteristics of vehicles
  https://github.com/Universite-Gustave-Eiffel/NoiseModelling/blob/v5.0.0/noisemodelling-emission/src/main/resources/org/noise_planet/noisemodelling/emission/railway/RailwayVehiclesCnossos.json
• CNOSSOS coefficients file coefficients related to the emission of vehicles
  https://github.com/Universite-Gustave-Eiffel/NoiseModelling/blob/v5.0.0/noisemodelling-emission/src/main/resources/org/noise_planet/noisemodelling/emission/railway/RailwayCnossosSNCF_2021.json

As it has been done in this script, we will update noiselevelfromsource in order to be able to switch to custom trains:

Hi Nicolas,

Sorry for the delay in replying.

For the moment, and until the update of noiselevelfromsource is available, we will propose modifications to RailwayTrainsets.json, RailwayVehiclesCnossos.json, and RailwayCnossosSNCF_2021.json where necesary.

I understand that these modifications should be proposed directly on GitHub, since I cannot find the JSON files in my copy of NoiseModelling_without_gui

Is it possible that the code is retrieving them directly from GitHub?

Thank you very much!!!!

Hello,

You can make your own NoiseModelling_without_gui by updating the json in your github fork of noisemodelling. The github action on your repository will automatically generate an artifact that you can download.

Just be sure that your branch is up to date with Universite-Gustave-Eiffel/NoiseModelling:main before editing the json files
