The default view doesn't show rail traffic, which also seems to add a lot of heat to the map. I haven't quite understood what the map is based on, but it says 24-hr LAeq - is this a 24-hour average or 24-hour max?

LAeq is an “energy” average, it’s all of the sound energy from the sources that’s averaged over 24 hours. It reflects human response to noise since.
