Overlay of different SQM measurements


Dear all,
I am a GIS student. Currently, I am preparing a paper on the modelling of light pollution.
The approach is to measure night sky brightness with a SQM at various spots in an urban area.
e.g. close to a highway,  close to a primary street, etc.
For my model I have consider that each of those measurements can overlap.
I need to understand how individual SQM measurements add up if they overlap.
I am looking for a formula that applies for the combination of light sources measured in 'mags/arcsec2'.
Anyone is experienced in this field?
