As I thought that the items that I read in papers over the last few weeks were incorrect and incomplete, I’ve created a data-set called “Transport for London services - measured train noise levels Zones 1&2”. Of course there is an “alternative tube map” of the data collected, using green/blue/red to show the loudest sections. This is similar in idea to the “tunnels” official tube map.
You can access the raw data from this Excel spreadsheet - https://1drv.ms/x/s!AvylRSGUkXTWvlJnFUbvDcHhb7xR
The data was collected on a Chromebook using the Decibel X PRO - Sound Meter dBA, Noise Detector app, https://play.google.com/store/apps/details?id=com.skypaw.decibel10pro
For each train I sat in the centre of the middle carriage. I travelled to every zone 1 and zone 2 stations out, plus more of the Central and Victoria.
So … would it be possible to include this data in the Journey Planner?
